Question 23.
State the universal law of gravitation and derive its Mathematical expression.
Answer:
Samacheer Kalvi 10th Science Model Question Paper 1 English Medium 1
This law states that every particle of matter in this universe attracts every other particle with a force. This force is directly proportional to the product of their masses and inversely proportional to the square of the distance between the centres of there masses. The direction of the force acts along the line joining the masses.

Force between the masses is always attractive and it does not depend on the medium where they are placed. Let m₁ and m₂ be the masses of two bodies A and B placed r metre apart in space

Force, F ∝ m₁ × m₂, F ∝ \(\frac{1}{r^{2}}\)
On combining the above two expressions,
F ∝ \(\frac{m_{1} \times m_{2}}{r^{2}}\)
F = \(\frac{G m_{1} m_{2}}{r^{2}}\)
Where G is the universal gravitational constant. Its value in SI unit is 6.674 × 10^-11 N m² kg^-2.

Question 24.

Question 27.
How is Aluminium extracted from Bauxite?
Answer:
Bauxite is the chief ore of aluminium. The extraction of aluminium from bauxite involves two steps:
(1) Conversion of bauxite into alumina – Baeyer’s process.
The conversion of Bauxite into Alumina involves the following steps:
Bauxite ore is finely ground and heated under pressure with a solution of concentrated caustic soda at 150° C to obtain sodium meta aluminate.

On diluting sodium meta aluminate with water, a precipitate of aluminium hydroxide is formed. The precipitate is filtered, washed, dried and ignited at 1000°C to get alumina.

(2) Electrolytic reduction of alumina – Hall’s process.
Aluminium is produced by the electrolytic reduction of fused alumina (Al₂O₃) in the electrolytic cell.

Part – IV

Answer all the questions. [3 × 7 = 21]

Question 33.
(a) (i) State the law of volume.
Answer:
When the pressure of gas is kept constant, the volume of a gas is directly proportional to the temperature of the gas.
(i.e.,) V ∝ T .
\(\frac{V}{T}\) = constant

(ii) Derive the ideal gas equation.
Answer:
The ideal gas equation is an equation, which relates all the properties of an ideal gas. An ideal gas obeys Boyle’s law, Charles’ law and Avagadro’s law,
According to Boyle’s law
PV = constant ……… (1)
According to Charles’s law,
\(\frac{V}{T}\) = constant …….(2)
According to Avagadro’s law,
\(\frac{V}{n}\) = constant ……(3)
After combining equations (1), (2) and (3)
\(\frac{P V}{n T}\) = constant ……..(4)

The above relation is called combined law of gases. If you consider a gas, which contains μ moles of the gas, the number of atoms contained will be equal to (i times the Avagadro’s number, NA
(i.e.,) n = μ N_A
using equation (5) equation (4) can be written as
PV / μ N_A T = constant

The value of the constant in the above equation is taken to be k_B, which is called as Boltzmann constant (1.38 × 10^-23 J K^-1). Hence, we have the following equation,
PV / μ N_A T = kB
PV = μ N_A k_B T
Here μ N_A k_B = R, which is termed as universal gas constant whose value is 8.31 Jmol^-1_1K^-1
PV = RT
Ideal gas equation is also called as equation of state because it gives the relation between the state variables and it is used to describe the state of any gas.

(b) How is ethanol manufactured from sugar-cane?
Answer:
Molasses is a dark coloured syrupy liquid left after the crystallization of sugar from the concentrated sugarcane juice. It contains 30 % of Sucrose, which cannot be separated by crystallization.

(i) Dilution of Molasses:
Molasses is first diluted with water,to bring down the concentration of sugar to about 8 to 10 percent.

(ii) Addition of Nitrogen Source:
Molasses contains enough nitrogenous matter to act as food for yeast during the fermentation process. If the nitrogenous matter is poor, ammonium sulphate or ammonium phosphate is added.

(iii) Addition of yeast:
This solution kept in large fermentation tank and yeast is added to it kept at about 303K for a few days. During this period, the enzymes invertase and Zymase present in yeast, convert sucrose into ethanol.
Samacheer Kalvi 10th Science Model Question Paper 1 English Medium 6
The fermented liquid is technically called wash.

(iv) Distillation of wash:
This wash containing 15 to 18% alcohol, is now subjected to fractional distillation. The main fraction drawn is an aqueous solution of ethanol which contains 95.5% of ethanol and 4.5% of water. This is called rectified spirit. This mixture is then refluxed over quicklime for about 5 to 6 hour and then allowed to stand for 12 hours. On distillation of mixture pure alcohol (100%) is obtained. This is called absolute alcohol.

Question 35.
(a) (i) Which hormone requires iodine for its formation? What will happen if intake of iodine in our diet is low?
Answer:
The formation of Thyroxine (T₄) and Triiodothyronine requires iodine. If there is an inadequate supply of iodine in our diet it leads to enlargement of thyroid gland called goitre.

(ii) What is the importance of rainwater harvesting?
Answer:
The importance of rainwater harvesting is as follows:

Overcome the rapid depletion of ground water level.
To meet the increased demand of water.
Reduces flood and soil erosion.
Water stored in ground is not contaminated by human and animal wastes and hence can be used for drinking purposes.

(iii) What is colostrum? How is milk production hormonally regulated?
Answer:
The first fluid which is produced from the mammary gland after child birth is called colostrum. Milk production from alveoli of mammary gland is stimulated by prolactin secreted from anterior pituitary.

[OR]

(b) (i) How does locomotion take place in leech?
Answer:
Locomotion in leech takes place by:

Looping or crawling movement: Crawling movement is brought about by the contraction and relaxation of muscles. The two suckers serve for attachment during movement.
Swimming movement: Leeches swim very actively and perform undulating movement in water.

(ii) How does Fossilization occur in plants?
Answer:
Fossilization in plants: The process of formation of fossil in the rocks is called fossilization.
The common methods of fossilization includes:

1. Petrifiction: Minerals like silica slowly penetrate in and replace the original organic tissue. This method can preserve hard and soft parts, (e.g.) wood fossils.

2. Mold and Cast: A replica of a plant or animal is preserved in sedimentary rocks. When the organism get buried in sediment it is dissolved by underground water leaving a hollow depression called Mold. It shows only the original shape and not the internal structure. Minerals or sediments fill the hollow depression and forms a cast.

3. Preservation: The entire plant may be preserved to protect from the organism from decay. Ice or amber (tree sap) can be used for preservation.

4. Compression: When the organism dies, the hard parts settle at the bottom of the sea bed and are covered by sediment. The process goes on continuously and the fossils are formed.

5. Infiltration: The precipitation of minerals takes place which later on infiltrate the cell wall. The process is brought about by several mineral element such as silica, calcium carbonate and magnesium carbonate.

Question 1.
Find the final temperature of a copper rod whose area of cross section changes from 10 m² to 11 m² due to heating. The copper rod is initially kept at 90 K. (Coefficient of superficial expansion is 0.0021 /K).
Answer:
Change in area ΔA = 11 – 10 = 1 m²
Initial temperature T₁ = 90 K
Let Final temperature be T₂K
A₀ = 10 m²
Coefficient of superficial expansion is
α_A = 0.0021 / k
\(\frac{ΔA}{A_0}\) = α_AΔT
\(\frac{1}{10}\) = 0.0021 ΔT
∴ ΔT = 0.0021 × 10
= 0.021
T₂ – T₁ = 0.021
T₂ – 90 = 0.021
∴ Final temperature T₂ = 90.021 K

VIII. Answer in detail.

Question 1.
Derive the ideal gas equation.
Answer:
The ideal gas equation is an equation, which relates all the properties of an ideal gas. An ideal gas obeys Boyle’s law and Charles’s law and Avogadro’s law.
According to Boyle’s law, PV = constant ………. (1)
According to Charles’s law,
\(\frac{V}{T}\) = constant ……… (2)
According to Avogadro’s law,
\(\frac{V}{T}\) = constant …….. (3)
After combining equations (1), (2) and (3), you equation. can get the following
\(\frac{V}{nT}\) = constant ……. (4)
The above relation is called the combined law of gases. If you consider a gas, which contains µ moles of the gas, the number of atoms contained will be equal to µ times the Avogadro number, N₀.
i.e., n = µN_A
Using equation (5), in equation (4) can be written as
\(\frac{PV}{µN_{A}T}\) = constant
The value of the constant in the above equation is taken to be K_B, which is called as Boltzmann constant (1.38 × 10^-23 JK^-1). Hence, we have the following equation:
\(\frac{PV}{µN_{A}T}\) = K_B
PV = µN_AK_BT
µN_AK_B = R
which is termed as universal gas constant whose value is 8.31 J mol^-1 K^-1.
PV = RT
Ideal gas equation is also called as equation of state because it gives the relation between the state variables and it is used to describe the state of any gas.

Question 2.
Explain the experiment of measuring the real and apparent expansion of a liquid with a neat diagram.
Answer:
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 6
To start with, the liquid whose real and apparent expansion is to be determined is poured in a container up to a level. Mark this level as L₁. Now, heat the container and the liquid using a burner. Initially, the container receives the thermal energy and it expands. As a result, the volume of the liquid appears to have reduced. Mark this reduced level of liquid as L₂. On further heating, the thermal energy supplied to the liquid through the container results in the expansion of the liquid. Hence, the level of liquid rises to L₃. Now, the difference between the levels L₁ and L₃ is called as apparent expansion, and the difference between the levels L₂ and L₃ is called real expansion. The real expansion is always more than that of apparent expansion.
Real expansion = L₃ – L₂
Apparent expansion = L₃ – L₁

Question 5.
Do all liquids expand on heating? give an example.
Answer:
All liquids do not expand on heating. If water is heated from 0°C to 4°C it contracts.

Question 6.
What will happen if two bodies are at different temperatures brought in contact with one other?
Answer:
There will be a transfer of heat energy from the hot body to the cold body until a thermal equilibrium is established between them.

Question 7.
What will happen if a cold body is placed in contact with a hot body?
Answer:
Some thermal energy is transferred from the hot body to the cold body. As a result, there is some rise in the temperature of the cold body and decrease in the temperature of the hot body. This process will continue until these two bodies attain the same temperature.

Question 8.

VII. Numerical problems.

Question 1.
Transform 100°C into K.
Answer:
T (kelvin) = (273 + t°C) K
= (273 + 100) K
= 373 K
100°C = 373 K

Question 2.
Convert 23 K into °C.
Answer:
T = 23 K
T°C = K – 273
= 23 – 273

23 K = -250°C

Question 3.
If the gap between steel sails on the railway track of 66 m long is 3.63 cm at 10°C. Then at what value of temperature will just touch of steel is 11 × 10^-6 °C.
Solution:
L₀ = 66 m = 6600 cm
α = 11 × 10^-6°C.
∆L = L_t – L₀ = 3.63
t₁ = 10°C
t₂ = ?
\(\alpha=\frac{\Delta \mathrm{L}}{\mathrm{L}_{\mathrm{o}} \Delta \mathrm{T}}\)
\(\begin{array}{l}{\Delta \mathrm{T}=\frac{\Delta \mathrm{L}}{\mathrm{L}_{0} \times \alpha}} \\ {\Delta \mathrm{T}=\frac{3.63}{6600 \times 11 \times 10^{-6}}}\end{array}\)
∆T = t₂ – t₁ = 50
⇒ t₂ – 10 = 50
⇒ t₂ = 50 + 10 = 60°C
so final temperature t₂ = 60°C

Question 4.
At what temperature do the ratings of Celsius and Fahrenheit scales coincide?
Answer:
Let T_B = T_B – x
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 12
∴ 180x = 100x – 3200
80x = -3200
x = –\(\frac{3200}{80}\) = -40°
x = -40°
∴ Hence -40°C and -40° f are identical Temperature.

Question 5.

α_L = 8.89 × 10^-6/°C

Question 6.
A balloon partially filled with the gas volume 30 m³ at on surface of the earth where pressure is 76 cm of Hg and temperature is 27°C. What will be the increase in the volume of the gas balloon when it rises to a height where the temperature becomes (-54°C) and pressure become 7.6 cm of Hg.
Solution:
Given, P₁ = 76 cm Hg, P₂ = 7.6 cm of Hg
V₁ = 30 m³, V₂ = ?
T₁ = 27 + 273 = 300 K
T₂ = -54 + 273 = 219 K
By gas equation
\(\frac{\mathrm{P}_{1} \mathrm{V}_{1}}{\mathrm{T}_{1}}=\frac{\mathrm{P}_{2} \mathrm{V}_{2}}{\mathrm{T}_{2}}\)
\(\mathrm{V}_{2}=\frac{\mathrm{P}_{1} \mathrm{V}_{1} \mathrm{T}_{2}}{\mathrm{T}_{1} \mathrm{P}_{2}}=\frac{76 \times 30 \times 219}{300 \times 7.6}\) = 219 m³
So increase in volume of gas = 219 – 30 = 189 m³.

Question 7.
If the area of metal changes by 0.22% when it is heated through 10°C, then calculate the coefficient of superficial expansion.
Answer:
\(\frac{ΔA}{A}\) = 0.22% = \(\frac{0.22}{100}\)
Change in temperature ΔT = 10°C
∴ Coefficient of cubical expansion
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 14
= 22 × 10^-6/°C

Question 8.
Using the ideal gas equation determine the value of universal gas constant. It is given that one gram, molecule of a gas at S.T.P occupies 22.4 litres.
Answer:
Pressure P = 1.013 × 10⁵ pa
Volume V = 22.4 lit I
= 22.4 × 10^-3 m³
Temperature T = 273 K
For one mole of a gas
PV = RT
∴ R = \(\frac{PV}{T}\)

= 8.31 J/mol/K

Question 9.
When a gas filled in a closed vessel is heated through 1°C, its pressure increases by 0.4% what is the initial temperature of the gas?
Answer:
Initial pressure P₁ = P
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 16
PT + 0.004PT = PT + P
0.004PT = P
∴ T = \(\frac{1}{0.004}\)
= 250 K
∴ Initial Temperature of the gas = 250 K

Question 10.
A vessel of volume 2000 cm³ contains 0.1 mole of O₂ and 0.2 mole of CO₂ . If the temperature of the mixture is 300 K then calculate the pressure exerted by it.
Answer:
n₁ = 0.1; n₂ = 0.2; R = 8.31 J/mol/K;

P = 3.74 × 10⁵ pa

VIII. Answer in detail.

Question 1.
Explain how the loss of heat (or transfer of heat) due to modes of transfer of heat is minimised in a thermos flask.
Answer:
Transfer of heat is thermos is minimised as under:
(i) By conduction: As in conduction heat can transfer by contact of a material medium. In thermos, the air is evacuated between the walls so heat transfer is stopped by conduction mode.

(ii) By convection: As convection mode also requires material (fluid) medium and there is nothing between the walls of thermos so heat does not transfer by connection mode.

(iii) By Radiation: As Ag polish is coated opaque on inner and outer walls of thermos radiation obeys the laws of refraction and reflection so no refraction takes place through opaque wall.
Reflection of outer radiation goes outside of the inner wall goes inside. So the transfer of heat is minimised by polishing.

Question 2.
Explain linear expansion in Solids.
Answer:
When a body is heated or cooled, the length of the body changes due to change in its temperature. Then the expansion is said to be linear or longitudinal expansion.

The ratio of increase in length of the body per degree rise in temperature to its unit length is called as the coefficient of linear expansion. The SI unit of Coefficient of Linear expansion is K^-1. The value of coefficient of linear expansion is different for different materials.
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 18
The equation relating the change in length and the change in temperature of a body is given below:
\(\frac{ΔL}{L_0}\) = α_LΔT
ΔL – Change in length (Final length – Original length)
L₀ – Original length
ΔT – Change in temperature (Final temperature – Initial temperature)
α_L – Coefficient of linear expansion.

Question 3.
Write a note on superficial expansion.
Answer:
If there is an increase in the area of a solid object due to heating, then the expansion is called superficial or areal expansion.

Superficial expansion is determined in terms of coefficient of superficial expansion. The ratio of increase in area of the body per degree rise in temperature to its unit area is called as coefficient of superficial expansion. Coefficient of superficial expansion is different for different materials. The SI unit of Coefficient of superficial expansion is K^-1.

The equation relating to the change in area and the change in temperature is given below:
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 19
\(\frac{ΔA}{A_0}\) = α_AΔT
ΔA – Change in area (Final area – Original area)
A₀ – Original area
ΔT – Change in temperature (Final temperature – Initial temperature)
α_A – Coefficient of superficial expansion.

Question 4.
What do you know about cubical expansion?
Answer:
If there is an increase in the volume of a solid body due to heating, then the expansion is called cubical or volumetric expansion. As in the cases of linear and areal expansion, cubical expansion is also expressed in terms of coefficient of cubical expansion. The ratio of increase in volume of the body ‘ per degree rise in temperature to its unit volume is called as coefficient of cubical expansion. This is also measured in K^-1.
Samacheer Kalvi 10th Science Guide Chapter 3 Thermal Physics 20
The equation relating to the change in volume and the change in temperature is given below:
\(\frac{ΔV}{V_0}\) = α_VΔT
ΔV – Change in volume (Final volume – Original volume)
V₀ – Original volume
ΔT – Change in temperature (Final temperature – Initial temperature)
α_V – Coefficient of cubical expansion.

IX. Hot Questions.

Question 1.
At what common temperature a block of wood metal appear equally cold or hot when touched?
Answer:
A body appears hot when touched if heat flows from the body to our hand and vice – versa. If there is no flow of heat across the body and hand, the body can not be identified while it is hot or cold as bodies are in thermal equilibrium with our body. So both block of wood and metal must have the temperature of our body i.e., 37°C.

Question 2.
At room temperature water does not sublimate from ice to steam. Give reason.
Answer:
The critical temperature of the water is much above room temperature.

Question 3.
Good conductors of heat are also good conductors of electricity and vice versa why?
Answer:
It is because of the movement of electrons present in the materials.

Question 4.
When does the Charle’s law fail?
Answer:
By Charle’s law at constant pressure
V ∝ T or T ∝ V
At T = 0 K volume must be zero but it is impossible, at low-temperature gases does not obey the characterise of the ideal gas. As the molecules come closer and force of attraction and repulsion takes place.

Question 5.
When sugar is added to tea it gets cooled, why?
Answer:
When sugar is added to tea, its heat gets shared by sugar. So temperature of tea decreases.

Question 6.
A metal disc has a hole in it. What happens to the size of the hole, when the disc is heated.
Answer:
The size of the hole increases. Because expansion takes place on heating.

Question 7.
Can the temperature of a body be negative on the kelvin scale.
Answer:
No, This is because absolute zero on the kelvin scale is the minimum possible temperature.

Answer:
இடம்:
மேற்கண்ட தொடர் மாநகராட்சியின் சிறப்புக் கூட்டத்தில் மாநகரத் தந்தை செங்கல்வராயன் முன்னிலையில் ம.பொ. சிவஞானம் கூறியது.

பொருள்:
ஆந்திராவின் தலைநகரம் சென்னையாக்க வேண்டும் என்று நீதிபதி வாஞ்சுவின் கருத்தை எதிர்த்து ம.பொ.சி. வாதிட்டார்.

விளக்கம்:
ஆந்திர மாநிலம் பிரியும்போது சென்னைதான் அதன் தலைநகராக இருக்க வேண்டும் என்று ஆந்திரத் தலைவர்கள் கருதினர். அந்நாள் முதல்வர் இராஜாஜிக்கு நிலைமையின் தீவிரத்தை உணர்த்திய போது, தலைநகர் காக்கத் தன் முதலமைச்சர் பதவியைத் துறக்கவும் அவர் முன்வந்தார். சென்னை மாகாணத்திலிருந்து பிரித்து ஆந்திரம் அமைவதற்காக ஏற்படுத்தப்பட்டிருந்த நீதிபதி வாஞ்சு தலைமையிலான ஒரு நபர் ஆணையம், ஆந்திரத்தின் தலைநகராகச் சென்னை இருக்க வேண்டும் என்ற இடைக்கால ஏற்பாட்டினைப் பரிந்துரைத்திருப்பதாக அதிகாரப்பூர்வமற்ற கருத்துகள் நிலவின. இதையொட்டி, ம.பொ.சி மாநகராட்சியின் சிறப்புக் கூட்டமொன்றை அப்போதைய மாநகரத் தந்தை செங்கல்வராயன் தலைமையில் கூட்டி, சென்னை பற்றிய தீர்மானமொன்றை முன்மொழிந்து, “தலையைக் கொடுத்தேனும் தலைநகரைக் காப்போம்” என்று முழங்கினார்.

கூத்து இசையுடன் கூடிய உடல் அசைவியக்கத்துடன் தொடர்புடையது. •
திறந்த வெளியை ஆடுகளமாக்கி ஆடை அணி ஒப்பனைகளுடன் இது வெளிப்படுத்தப்படு கிறது. களத்து மேடுகளில் நிகழ்த்தப்பட்ட தெருக்கூத்து, தெருச்சந்திப்புகளிலும் நிகழ்த்தப்படுகிறது.
ஒரு கதையை இசை, வசனம், ஆடல், பாடல், மெய்ப்பாடு ஆகியவற்றை ஒருங்கிணைத்து வழங்குவர். திரௌபதி அம்மன் வழிபாட்டின் ஒரு பகுதியாகவும் இது இருக்கிறது.
தெருக்கூத்து, வேளாண்மை செய்வோரின் கலையாக இருந்தது.
அருச்சுனன் தபசு’ என்பது மழை வேண்டி நிகழ்த்தப்படும் கூத்தாகும். கூத்துக்கலைஞர், கூத்தைக் கற்றுக்கொடுப்பவர் ஆகியோரின் அடிப்படையிலும் காலம். இடம் போன்றவற்றின் அடிப்படையிலும் கூத்து நிகழ்த்தப்படுவதில் சிறுசிறு மாறுபாடுகள் உள்ளன.
தெருக்கூத்து, பொழுதுபோக்குக் கூறுகளைப் பெற்று நாடகமாக வளர்ச்சியடைந்துள்ளது. இதனைக் கதகளி போன்று செவ்வியல் கலையாக ஆக்கும் முயற்சிகள் மேற்கொள்ளப்படுகின்றன.

Answer:
Samacheer Kalvi 10th Tamil Model Question Paper 5 - 1

நவீன கவிதை:
நவீன கவிதையில் பூவினை இறுக்கி முடித்தல் காம்பு அறுந்துவிடும். அதைத் தளரப் பிணைத்தால் தரையில் நழுவும். வாசலில் மரணம் இருப்பது தெரிந்தும் கவலைப்படாமல் சிரிக்கும் அந்தப் பூவைத் தொடுத்துக் கொண்டு இருக்கின்றனர்.

நாட்டுப்புறப்பாடல்:
நாட்டுப்புறப்பாடலில் இறைவனுக்குப் போடப்போகும் பூவைத் தொடுப்பது எப்படிக் கையால் தொடுத்தால் காம்பு அழுகிப் போகும். விரலால் தொடுத்தால் வெம்பிப் போய்விடும். அதனால் தங்கத் துரட்டி கொண்டு நான் இறைவனுக்கு மாலையாகத் தொடுக்கிறேன்.

ஒப்பிடு :
புதுக்கவிதையில் தொடுக்கும் பூ மரணத்திற்குப் போடப்படுகிறது. ஆனால் நாட்டுப்புறப் பாடலில் தொடுக்கும் பூ இறைவனுக்குப் போடப்படுகிறது. இருவரும் தொடுக்கும் பூ ஒன்றே ஆனால் அது போய் சேர்கின்ற இடம் தான் வெவ்வேறாக இருக்கிறது.

தமிழ்த்தாயை சுந்தரனார் அவர்கள் தமிழ்த்தாய் வாழ்த்துப் பாடலில், நீரலைகள் எழுந்து ஆர்ப்பரிக்கின்ற கடலைத் தன் ஆடையாய் உடுத்திக் கொண்டுள்ள நிலமாகிய பெண்ணுக்கு அழகிய முகமாகத் திகழ்வது பாரத கண்டம். அம்முகத்திற்கு அழகிய பிறை போன்ற நெற்றியாகத் திகழ்வது. தெற்குப்பகுதி, அந்நெற்றியில் இட்டுக்கொண்ட குங்குமம் போல புகழ் ஒளி வீசித் திகழ்வது திராவிட நாடு. அக்குங்குமத்தின் வாசனையைப் போல் அனைத்துப் பகுதி மக்களும் இன்பம் அடையும்படி எட்டுத் திசைகளிலும் பரவி வாழ்கின்ற தமிழ் என்னும் தெய்வமே தொன்று தொட்டு வாழ்ந்தாய் என்றாலும் உன் பெருவாழ்வு புதுமைக்குப் புதுமையாய் இன்றும் இளமையாய் விளங்குகிறது. தமிழ்த்தாயே உன் பேராற்றலை வியந்து செய்வதறியாது மெய்மறந்து வாழ்த்துகின்றோம் என வாழ்த்துகின்றார்.

அன்பும் பண்பும் குணச்சித்திரமும் கொண்ட தலைவர் அவர்களே! தேர்ந்தெடுத்த பூக்களைப் போன்று வரிசை தொடுத்து அமர்ந்திருக்கும் ஆன்றோர்களே! அறிஞர் பெருமக்களே! வணக்கம். இயற்கை கொலு வீற்றிருக்கும் காட்சியைப் பெரிய கலைநிகழ்வே நடப்பதான தோற்றமாகக் கம்பன் காட்டும் கவி… தண்டலை மயில்கள் ஆட…. இவ்வுரையைத் தொடர்க!
Answer:
தண்டலை மயில்கள் ஆட
உள்ளதை உணர்ந்தபடி கூறுவது கவிதை கவிஞரின் உலகம் இட எல்லை அற்றது கால எல்லை அற்றது. கவிஞனின் சிந்தைக்குள் உருவாகும் காட்சியைச் சொல்லைக்கொண்டு எழுப்புகிறான். அவன் கண்ட காட்சிகள் அதற்குத் துணைபுரிகின்றன. கேட்ட ஓசைகள் துணைபுரிகின்றன. விழுமியங்கள் துணைபுரிகின்றன. ஒப்புமைகள் துணைபுரிகின்றன. கலையின் உச்சம் பெறுவதுதான் அவன் எல்லையாகிறது. கம்பன் அப்படிப்பட்ட கவிஞன் அதனால்தான் கம்பன் இசைத்த கவியெல்லாம் நான் என்று பாரதி பெருமைப்படுகிறார்.

ஆறு இயற்கையின் தோற்றமாக இல்லாமல் ஓர் ஓவியமாக விரிகிறது. அதை உயிரெனக் காணும் அந்த அழகுணர்ச்சி கவிதையாகி ஓடி நெஞ்சில் நிறைகிறது. கவிதை கவிஞன் மூலம் தன்னையே வெளிப்படுத்திக் கொள்கிறது. அது எப்படி வருகின்றதோ அதை மாற்றினால் அழகு குன்றும் மீண்டும் மீண்டும் மறிதரும் சந்தம் உணர்வுகளை நம்முள் செலுத்துகிறது உள்ளம் சூறையாடப்படுகிறது.

இயற்கை கொலுவீற்றிருக்கும் காட்சியைப் பெரிய கலைநிகழ்வே நடப்பதான தோற்றமாகக் கம்பன்கவி காட்டுகிறது. ஒன்றின் இருப்பால் இன்னொன்று அடையாளப்படுத்தப்படுகிறது என்ற மெய்யியலைக் கொண்டு ஒரு நாட்டின் பெருமையைப் புலப்படுத்தும் கம்பனின் உத்தி போற்றத்தக்கது. இராமனுடைய மாநிற மேனியை வருணிக்கும் கம்பன், மை, மரகதம் என்றெல்லாம் உவமை சொல்லி நிறைவாகச் சொல்ல இயலவில்லை என்பதை ‘ஐயோ’ என்ற சொல்லில் வைப்பதன் வாயிலாக அதை இயன்றதாக்குகிறான். கவிதைகள் மூலம் பெறும் இன்பங்கள் எத்தனையோ! அதில் ஒன்று சந்த இன்பம். பொருள் புரியாவிடிலும் சந்த இன்பம் மகிழ்ச்சியூட்டுகிறது. ஓசை தரும் இன்பம் உவமையிலா இன்பமடா என்று பாரதி சொல்வதை இதில் உணர முடியும். உலக்கையால் மாறி மாறி இடிக்கும் ஒத்த ஓசையில் அமைந்த சந்தம் இடிக்கும் காட்சியைக் கண்முன் எழுப்புகிறது.

இவ்வாறு கம்பன் கவி மனதை விட்டு நீங்காது என்றும் நிறைந்திருக்கும் என்று தன் உரையை முடிக்கிறார்.

Koothu
Therukoothu is, as its name indicates, a popular form of theatre performed in the streets. It is performed by rural artists. The stories are derived from epics like Ramayana, Mahabharatha and other ancient puranas. There are more songs in the play with dialogues improvised by the artists on the spot. Fifteen to twenty actors with a small orchestra forms a koothu troupe. Though the orchestra has a singer, the artists sing in their own voices. Artists dress themselves with heavy costumes and bright makeup. Koothus is very popular among rural areas.

தெருக்கூத்து
தெருக்கூத்து என்பது பெயரைப் போலவே தெருக்களில் நடைபெறும் புகழ் பெற்ற கூத்தாகும். இது நாட்டுப்புறக் கலைஞர்களால் அரங்கேற்றப்படுகிறது. இதன் கதைகள் இதிகாசமாகிய இராமாயணம், மஹாபாரதம் மற்றும் புராணங்களைத் தழுவியது. இதில் மிகையாக பாடல்கள் இடம் பெறுதலும் கதை விமர்சனங்கள் கூத்தாடிகள் உடனுக்குடன் தானே முன்முயற்சியின்றி உரைப்பவையாக இருக்கும். தெருக்கூத்து 15 முதல் 20 கூத்தாடிகளுடன் கூடிய இசைக்குழுவினருடன் கூடியது ஆகும். இசைக் குழுவினரிடம் பாடகர் இருப்பினும் தெருக்கூத்தாடிகள் தானே முனைந்து பாடுவார்கள். தெருக்கூத்தாடிகள் அபார ஆடை அலங்காரமும் பளிச்சென்ற தோற்றத்துடனும் காணப்படுவர். தெருக்கூத்து நாட்டுப்புறங்களில் பிரசித்தி பெற்றதாகும்.

Question 43.
(அ) தமிழின் சொல்வளம் பற்றியும் புதிய சொல்லாக்கத்திற்கான தேவை குறித்தும் தமிழ் மன்றத்தில் பேசுவதற்கான உரைக் குறிப்புகளை எழுதுக.
Answer:
முன்னுரை:
கால வெள்ளத்தில் கரைந்துபோன மொழிகளுக்கிடையில் நீந்தி தன்னை நிலை நிறுத்திக் கொண்டுள்ளது தமிழ். சொல்வளம் இலக்கியச் செம்மொழிகளுக்கெல்லாம் பொது என்றாலும் தமிழ் மட்டுமே அதில் தலை சிறந்ததாகும். தமிழின் சொல் வளத்தை நாம் பலதுறைகளிலும் காணலாம்.

தமிழின் சொல் வளம்:
ஆங்கிலம் போன்ற மொழிகளில் இலையைக் குறிக்க ஒரே ஒரு சொல் மட்டுமே உள்ளது. ஆனால் தமிழ்மக்கள் இலையை அதன் வன்மை, மென்மை, இவற்றைக் கொண்டு இலை, தோகை, ஓலை என பாகுபாடு செய்துள்ளனர். இதுமட்டுமன்றி தாவரங்கள், மணிவகை, இளம்பயிர்வகை, காய்கனி வகை, அடி, கிளை கொழுந்து என அனைத்து உறுப்புகளுக்கும் சொற்களைப் பகுத்து வைத்துள்ளனர்.

பூவின் நிலைகளைக் குறிக்கும் சொற்கள்:
அரும்பு: பூவின் தோற்றநிலை போது, பூ விரியத் தொடங்கும் நிலை மலர், பூவின் மலர்ந்த நிலை, வீ: மரம், செடியிலிருந்து பூ கீழே விழுந்த நிலை செம்மல், பூ வாடின நிலை

தமிழின் பொருள் வளம்:
தமிழ்நாடு எத்துணைப் பொருள் வளமுடையது என்பது அதன் வினைபொருள் வகைகளை நோக்கினாலே விளங்கும். தமிழ் நாட்டு நெல்லில் செந்நெல் வெண்ணெல், கார்நெல் என்றும், சம்பா, மட்டை, கார் என்றும் பல வகைகள் உள்ளன. அவற்றில் சம்பாவில் மட்டும் ஆவிரம் பூச்சம்பா, ஆனைக் கொம்பன் சம்பா, குண்டு சம்பா, குதிரை வாலிச்சம்பா, சிறுமணிச்சம்பா, சீரகச்சம்பா முதலிய அறுபது உள் வகைகள் உள்ளன. இவற்றோடு வரகு, காடைக்கண்ணி குதிரைவாலி முதலிய சிறு கூலங்கள் தமிழ் நாட்டிலன்றி வேறெங்கும் விளைவதில்லை.

முடிவுரை:
பண்டைத் தமிழ் மக்கள் தனிப்பெரும் நாகரிகத்தை உடையவராக இருந்திருக்கின்றனர். ஒரு நாட்டாரின் அல்லது இனத்தாரின் நாகரிகத்தை அளந்தறிவதற்கு உதவுவது மொழியேயாகும். ஆகவே “நாடும் மொழியும் நமதிரு கண்கள்” என்ற கூற்றின்படி பொருட்களைக் கூர்ந்து நோக்கி நுண்பொருட் சொற்களை அமைத்துக் கொள்வது நம் தலையாய கடமையாகும்.

(ஆ) நெகிழிப் பைகளின் தீமையைக் கூறும் பொம்மலாட்டம் உங்கள் பள்ளியின் ஆண்டு விழாவில் நிகழ்த்தப்படுகிறது. அதற்குப் பாராட்டுரை ஒன்றினை எழுதுக.
Answer:

அனைவருக்கும் வணக்கம். பொம்மலாட்டம் என்பது மக்கள் விரும்பி பார்க்கும் ஒரு வகை கூத்துக் கலையாகும்.
பார்ப்பவரின் கண்ணையும் கருத்தையும் மனதையும் ஒரே நேரத்தில் ஆட்கொள்ளக்
கூடியதாக இருக்கிறது.
நெகிழிப்பைகளின் வரவால் மக்கள் எவ்வாறு அவதிப்படுகின்றனர் என்பதை இந்த பொம்மலாட்டம் மூலம் மாணவர்களுக்குப் புரியும் வகையில் மிக எளிமையாக விளக்கினார்கள். பொம்மலாட்டத்தைத் தோற்பாவைக் கூத்து என்றும் அழைப்பர்.
தோலில் செய்தவெட்டு வரைபடங்களை விளக்கின் ஒளி ஊடுருவும் திரைச்சீலையில் பொருத்தி, கதைக்கேற்ப மேலும் கீழும் பக்கவாட்டிலும் அசைத்துக்காட்டி உரையாடியும் பாடியும் காட்டுவது தோற்பாவைக் கூத்து.
தோலால் ஆன பாவையைக் கொண்டு நிகழ்த்தும் கலையாதலால் தோற்பாவை என்னும்
பெயர் பெற்றது.
இசை, ஓவியம், நடனம், நாடகம், பலகுரலில் பேசுதல் ஆகியவை இணைந்துள்ளன.
கூத்து நிகழ்த்தும் திரைச் சீலையின் நீளம், அகலம் ஆகியன பாவையின் அமைப்பையும் எண்ணிக்கையையும் பொறுத்து வேறுபடுகின்றன.
இந்நிகழ்ச்சியில் பாவையின் அசைவு உரையாடல் இசை ஆகியனவற்றோடு ஒளியும் முதன்மை பெறுகின்றது.
பாவை குறித்த செய்திகள் சங்ககாலம் முதல் பதினெட்டாம் நூற்றாண்டுவரையான தமிழ் இலக்கியங்களில் காணப்படுகின்றன.
• திருக்குறளில் பரப்பாவையைப் பற்றி குறிப்பிடப்பட்டுள்ளது. திருவாசகத்திலும் பட்டினத்தார் பாடலிலும் தோற்பாவைக் கூத்து விளங்குகிறது.
தோற்பாவைக் கூத்து கையுறைப் பாவைக் கூத்து. பொம்மலாட்டம் என்பனவாகவும் மாற்றம் பெற்றுள்ளது.
நெகிழி அல்லது பிளாஸ்டிக் என்பது ஒரு பொருள்.
ஏதாவது ஒரு நிலையில் இளகிய நிலையில் இருந்து பின்னர் இறுதி திட நிலையை அடைவதைக் குறிக்கும் சொல் ஆகும்.
பொருள் மண்ணுக்குள் சென்றால் சீக்கிரம் மக்காமல் அப்படியே இருந்து விடுகிறது.
அதனால் மரங்களில் வேர்களுக்கு ஆக்சிஜன் கிடைக்கக் கடினமாக இருக்கிறது.
எந்த ஒரு பொருள் பூமியில் மக்கவில்லையோ அது மனித இனத்திற்கே பேராபத்து என்பதை இந்தப் பொம்மலாட்டம் மூலமாக மாணவர்களுக்கு மிக எளிதாகச் சென்று சேர்ந்தது.
பொம்மலாட்டம் கலைஞர் அனைவருக்கும் பாராட்டுகளைத் தெரிவித்துக் கொள்கிறோம்.

Question 44.
(அ) இராமானுசர் நாடகக் கதையைச் சுருக்கி எழுதுக.
Answer:
முன்னுரை:
நாளுக்கு ஒருமுறை மலர்வது சண்பகம். ஆண்டுக்கு ஒருமுறை மலர்வது பிரம்ம கமலம். பன்னிரண்டு ஆண்டுக்கு ஒரு முறை மலர்வது குறிஞ்சி. நம் தலைமுறைக்கு ஒரு முறை பிறப்பவர்கள் ஞானிகள். அவர்களுள் இராமானுசர் பற்றி இக்கட்டுரையில் காண்போம்.

தண்டு, கொடியுடன் பூரணர் இல்லம் அடைதல் :
திருமந்திரத் திருவருள் பெறத் தண்டும், கொடியுமாக இராமானுசரை வரச் சொல்லுங்கள் என்னும் செய்தி, பூரணரால் திருவரங்கத்திற்கு அனுப்பப்பட்டதன் அடிப்படையிலேயே இராமானுசர் – கூரேசர் முதலியாண்டான் ஆகியோர் பூரணர் இல்லத்திற்கு வந்தனர். சுவாமிகளே ! வணக்கம்! தங்கள் கட்டளைப்படி புனித திருமந்திரத் திருவருளுக்காக வந்துள்ளோம் என கூரேசர் பூரணரிடம் கூறினார். தண்டு; கொடியுடன் உங்களைத்தானே வரச் சொன்னேன் பிறகெதற்குத் தாங்கள் உறவுகளை உடன் அழைத்து வந்துள்ளீர்கள் என பூரணர், இராமானுசரிடம் கேட்டார். அதற்கு சுவாமிகள் என்மேல் கோபம் கொள்ளக் கூடாது. தங்கள் விருப்பப்படியேதான் வந்துள்ளேன். தாங்கள் கூறிய தண்டு, கொடிக்கு இணையானவர்கள் இவர்கள். எனவே அடியவர்களாகிய எங்கள் மேல் கோபம் கொள்ளாது பரிவு கொண்டு திருவருள் புரிய வேண்டும் என்று இராமானுசர் கூறினார். உடனே பூரணர் இவர்களை நீங்கள் தண்டு, கொடி எனக் கூறியதால் உங்கள் மூவருக்குமாகத் திருமந்திரத்தைக் கூறுகிறேன் என்றார்.

பூரணர் கட்டளை:
பூரணர் மூவரையும் வீட்டிற்குள் அழைத்து நான் கூறுவதை நன்றாகக் கவனியுங்கள். நான் கூறப் போகின்ற திருமந்திர மறைபொருள்கள் உங்கள் மூவருக்கு மட்டுமே தெரிய வேண்டும். வேறு யாரிடமாவது இதை நீங்கள் கூறுவீர்கள் எனில், அது ஆசிரியர் கட்டளையை மீறியதாகும். அப்படி நடந்தால் அதற்குத் தண்டனையாக நரகமே கிட்டும். ஆச்சாரிய நியமத்தை மீறிய பாவிகளாக நீங்கள் மாற மாட்டீர்கள் என்னும் நம்பிக்கையுடன் திருமந்திரத்தைக் கூறுகிறேன் என்று கூறி பின்னர், ‘திருமகளுடன் கூடிய நாராயணனின் திருப்பாதங்களைப் புகலிடமாகக் கொள்கிறேன். திருவுடன் சேர்ந்த நாராயணனை வணங்குகிறேன்’ என்ற திருமந்திரத்தை பூரணர் கூற மூவரும் மூன்று முறை உரக்கச் சொன்னார்கள். ஆண்டவனின் அடியவர்களாகிய எங்களுக்கு திருவருள் கொண்டு திருமந்திரம் கூறியமைக்கு மிக்க நன்றி என்று கூறி விடைப்பெற்றனர்.

பொதுமக்களுக்கு மந்திரத்தை கூறுதல்:
திருக்கோட்டியூர் சௌம்ய நாராயணன் திருக்கோவிலின் மதில் சுவரின் மேல் இராமானுசர் நின்று கொண்டு, கீழே பொதுமக்களுடன் கூரேசரும், முதலியாண்டானும் நின்றுக் கொண்டு உரத்த குரலில் பக்தியால் முக்திக்கு வழிகாணத் துடிப்பவர்களே! அருகில் வாருங்கள் அனைவரும். இன்னும் அருகில் வாருங்கள் கிடைப்பதற்கரிய பிறவிப்பிணியைத் தீர்க்கும் அருமருந்தான திருமந்திரத்தை உங்களுக்குக் கூறுகிறேன். அனைவரும் இணைந்து மந்திரத்தைச் சொல்லுங்கள் என இராமானுசர் பொதுமக்களிடம் கூறினார். இராமானுசருடன் சேர்ந்து அனைவரும் மூன்று முறை கூறுகின்றனர்.

கோபம் கொண்ட பூரணர்:
பூரணரின் வார்த்தையை மீறியதற்காக கோபம் கொண்ட பூரணரிடம், இராமானுசர் மன்னிப்பு கேட்டார். ஞான குருவே ! முதலில் எம்மை மன்னித்தருளுங்கள். நாங்கள் செய்த இரண்டகத்திற்குக் கொடிய தண்டனையான நரகமே கிட்டும் என்பதை நான் மறக்கவில்லை என இராமானுசர் பூரணரிடம் கூறினார்.

பூரணருக்கு இராமானுசர் அளித்த விளக்கம்:
கிடைப்பதற்கரிய மந்திரத்தைக் தங்களின் திருவருளால் நான் பெற்றேன். அதன் பயன் எனக்கு மட்டுமே கிட்டும். அந்த அருமந்திரத்தை அனைவருக்கும் கூறினால், உழன்று பேதை வாழ்வு வாழ்ந்து வரும் பல்லாயிரக்கணக்கான மக்கள் தங்களின் பிறவிப்பிணி நீங்கி பேறு பெறுவார்கள். இதனால் நான் மட்டுமே தண்டனை கிடைக்கப்பெற்று நரகத்தைச் சேர்வேன். ஆனால் என் மக்கள் அனைவர்க்கும் நலம் கிட்டும். எல்லாரும் நலமுடன் வாழ்வார்கள் என இராமானுசர் விளக்கமளித்தார்.

இராமானுசருக்கு பூரணர் ஆசி வழங்குதல்:
இராமானுசரிடம் பூரணர் உங்களுக்கு இருந்த பரந்த அருள் உள்ளம் இதுவரை எனக்கு இல்லாமல் போனதே என்று கூறி அவரை மன்னித்து ஆசி வழங்கி, என் மகன் சௌம்ய நாராயணனைத் தங்களிடம் அடைக்கலமாக அளிக்கிறேன் என்றார்.

இராமானுசர் விடை பெற்று செல்லுதல் :
பூரணரிடம், இராமானுசர் முன்பு கிடைப்பதற்கரிய திருமந்திரத்தை எமக்களித்தீர்கள். இன்றோ உங்களின் அன்புத் திருமகனையும் எமக்களித்துள்ளீர்கள். நான் பெரும் பேறு பெற்றவன் ஆகிவிட்டேன். மிக்க மகிழ்ச்சி விடை தாருங்கள்! புறப்படுகிறோம் என்று கூறி விடைப் பெற்றார்.

முடிவுரை:
இராமானுசர் புனித திருமந்திரத் திருவருள் தனக்கு மட்டுமே கிடைத்தால் தான் ஒருவனுக்கு மட்டுமே என்ன பயன் எனக் கருதி எளிய மக்களுக்கும் திருமந்திரத்தைக் கூறி பிறவிப்பிணியை நீக்கியவர்.

(ஆ ) ‘பாய்ச்சல்’ துணைப்பாடப் பகுதியின் கதையைச் சுருக்கி எழுதுக. முன்னுரை:
உண்மைக் கலைஞன் தன் கலையில் முழு ஈடுபாட்டைக் காட்டுவான். கலை நிகழ்வின் ஊடாக அவன் பெருமிதம், வெளிப்பட்டுக் கொண்டே இருக்கும். தன்னொத்த கலைஞர்களிடமிருந்து வேறுபட்டுத் தமக்கெனத் தனித் தன்மைகளைக் காட்டுவான்.

அழகு கண்ட காட்சி :
அழகு, தலையை நீட்டிப் பார்த்தான். இவனையொத்த சிறுவர்கள் புழுதி பறக்க ஓடிக்கொண்டு இருந்தார்கள். நாதசுரமும், மேளமும் ஒன்றாக இழைந்து ஒலித்தது. இவன் குனிந்து பார்த்தான். இரண்டு கால்கள் மின்னல் வெட்டி மறைவது போலத் துள்ளிப் பாய்ந்து சென்றன. அந்தக் கால்கள் மனிதக் கால்களிலிருந்து மாறுபட்டு இருப்பதைக் கண்டான்.

அனுமார் காட்சி :
அனுமார் வலது காலையும், இடது காலையும் மாறி மாறித் தரையில் உதைத்து வேகமாகக் கைகளை வீசி நடக்க ஆரம்பித்தார். சதங்கையும், மேளமும், நாதசுரமும் ஒன்றாக இழைந்தன. அனுமார் தாவிக் குதித்துக் குறுக்கும் நெடுக்குமாகப் பாய்ந்து சென்றார். நீண்ட வால் மேலே சுழன்று சரேலென்று தரையில் படர்ந்து புழுதியைக் கிளப்பியது.

திடீரென்று மேளமும், நாதசுரமும் துரித கதியில் ஒலிக்கத் தொடங்கின. பெருங்குரல் எழுப்பியபடி அனுமார் பந்தல் கால் வழியாகக் கீழே குதித்தார். அனுமார் வாலில் பெரிய தீப்பந்தம். ஜ்வாலை புகைவிட்டுக் கொண்டு எரிந்தது. அழகு அவர்கள் அருகில் சென்றான். அருகில் அழகு சென்றதும் வாலைக் கொடுத்துவிட்டுக் கைகளை நன்றாக உதறியவாறு ‘ஓம் பேரு’ என்றான்.

அனுமார் பாய்ச்சல்:
அனுமார் இன்னொரு பாய்ச்சல் பாய்ந்து வேகமாக ஆட ஆரம்பித்தார். வர வர ஆட்டம் துரிதகதிக்குச் சென்றது. பதுங்கியும் பாய்ந்தும் ஆடினார். ஆட ஆட, புழுதி புகைபோல் எழுந்தது. கழுத்துமணி அறுந்து கீழே விழுந்தது. ஒன்றையும் பொருட்படுத்தாமல் ஆட்டத்தில் தன்னை இழந்தவராக ஆடினார்.

அழகின் அனுமார் ஆட்டம் :
அழகு எழுந்து தரையில் கிடந்த வாலை இடுப்பில் கட்டிக் கொண்டு சதங்கையை எடுத்தான். கையிலிருந்த சதங்கை கீழே நழுவ அச்சத்தோடு அனுமாரைப் பார்த்தான். காலில் சதங்கையைச் சுற்றிக்கொண்டு அனுமார் மூஞ்சியை எடுத்து மாட்டிக்கொண்டு தான் கண்டதையெல்லாம் மறுபடியும் மனதில் இருத்தி ஆட்டத்தை ஆட ஆரம்பித்தான். முதலில் மரத்தில் இருந்து கீழே குதிக்கும் ஆட்டத்தை ஆடினான். இவன் ஆட்டம் தாளகதிக்கு மிகவும் இணங்கி வருவது அனுமாருக்கு மகிழ்ச்சி அளித்தது. அழகு சாய வேட்டியை வாலின் நுனியில் சுற்றி நெருப்பு வைத்தான். வாயால் ஊதி நெருப்பைக் கனிய வைத்துப் பெரிதாகக் கத்திக்கொண்டு அனுமாரை நோக்கிப் பாய்ந்தான். மாறாத புன்னகையோடு துள்ளித் துள்ளி கையும் காலும் குழைந்து நெளிய ஆடினான். அனுமார் அவனை உற்றுப் பார்த்தார். மனம் தன்னிலை இழந்தது.

முடிவுரை:
இக்கலைஞனின் கலை ஈடுபாட்டில் அவனுக்கு வயதோ உடற்சோர்வோ, பாதிப்பை ஏற்படுத்துவதில்லை. தன் கலையைப் பின்பற்ற தகுந்த வாரிசு உருவாகிறபோது அவன் கொள்கிற மகிழ்ச்சியும், பெருமிதமும் அளப்பரியது.

Answer:
விடுதலைப் போராட்டத்தில் தமிழர்கள்
முன்னுரை:
சும்மா கிடைக்கவில்லை சுதந்திரம். எத்தனை கண்ணீர்களின் கதை இது. இன்று நீ சிந்தும் புன்னகை ஒவ்வொன்றிற்கும் கொடுத்த விலை எத்தனையோ?

“தண்ணீர் விட்டோ வளர்த்தோம் சர்வேசா
இப்பயிரைக் கண்ணீரால் காத்தோம் கருகத்திருவுளமோ” (- எனும்)

பாடலைப்போல தியாகிகள் செய்த தியாகங்கள் எத்தனையோ, ஆண், பெண் வேறுபாடின்றி அன்னியனை விரட்டிய கதைகள் எத்தனையோ.

வீரபாண்டிய கட்டபொம்மன்:
அன்னியர் எண்ணங்களை எல்லாம் சின்னாபின்னமாக்கிய முன்னோடியாகக் கருதப்படுபவர் வீரபாண்டிய கட்டபொம்மனே (1760 – 99) ஆவார். பாஞ்சாலாங்குறிச்சியின் சரித்திரப் புதல்வனாய் ஆங்கிலேயருக்கு வட்டி கொடுக்க மறுத்து இராமநாதபுரம் பாளையக்காரர்களுடன் இணைந்து

ஆங்கிலேயன் மேல் போர் தொடுத்ததை நாடறியும். போரில் பின்னடைவு ஏற்பட்டாலும், புதுக்கோட்டையில் அடைக்கலமானபோது விஜயரகுநாத தொண்டைமானால் காட்டிக் கொடுக்கப்பட்டவர். இறுதிவரை வணங்காமுடியாய் இருந்தவர், கயத்தாற்றில் கயிற்றினுக்கு இரையானபோதும், இம்மண்ணினை நோக்கியபடியே இறந்திட வேண்டுமென்று முகத்திற்கு திரை இடாதவன் என கட்டபொம்மனின் பெருமையைச் சொல்லிக் கொண்டே போகலாம்.

மருது சகோதரர்கள் சரணடைதல்:
18-ஆம் நூற்றாண்டில் நெல்லை மாவட்டத்தில் நெற்கட்டும் செவலில் குறுநில மன்னனாக 1714ல் பிறந்த பூலித்தேவனும், உயிர்போயினும் ஒரு நெல் மணிகூட வரியாகத் தர இயலாது என மறுத்து போர்க்கொடி தூக்கியவன். பாளையக்காரர் துணையுடன் 17 ஆண்டுகள் போரிட்டு இறுதியில் 1764ல் வீரமரணம் அடைந்தார்.

சிவகங்கையை ஆண்ட மருது சகோதரர்கள் தங்களுடைய உள் விவகாரங்களில் ஆங்கிலேயர் தலையிடுவதை எதிர்த்தனர். இவர்கள் போர் தொடுக்குமுன் ஆங்கிலேயர் தலையிடுவதை எதிர்த்தனர். இவர்கள் போர் தொடுக்குமுன் ஆங்கிலேயர் சிவகங்கையை 1801ல் தாக்கினார்கள். நான்கு மாதங்கள் போர் நடந்தது. மருது சகோதரர்கள் தலைமறைவாயினர். அவர்களைப் பிடித்திட அன்னியருக்கு இயலவில்லை. “பாண்டியனே, நீ வெளிவரவில்லையானால் நீ கட்டிய காளையர் கோவில் இடித்து தரைமட்டமாக்கப்படும்” எனக் கூறியதால் மருது சகோதரர்கள் தாமாகவே முன்வந்து சரணடைந்தபோது தூக்கிலிடப்பட்டனர்.

வீரமங்கை வேலுநாச்சியார்:
வடக்கே ஜான்சி ராணிக்கு ஈடாக தமிழ் மண்ணிற்கு 18-ஆம் நூற்றாண்டைச் சார்ந்த வீரமங்கை வேலு நாச்சியாரைச் சொல்லலாம். சிவகங்கைச் சீமையை ஆண்ட முத்துவடுகநாதருக்கு துணையாக வாளேந்திப் போர் புரிந்தார். கர்னல் ஸ்மித்துடன் செய்த போர் குறிப்பிடத்தக்கது. இறுதியில் இம்மண்ணிற்காக உயிர் துறந்தார்.

தஞ்சைத் தமிழ் மகளாகிய தில்லையாடி வள்ளியம்மை தென்னாப்பிரிக்காவில் பிறந்தாலும் தம் பதினாறு வயதினிலே போராட்டத்தில் உயிர் நீத்தார். கறுப்பர் – வெள்ளையர் போராட்டத்தில் வெள்ளையன் ஒருவன் காந்தியைச் சுட முயன்ற போது தன்னைச் சுடுமாறு வீர முழக்கமிட்டார். 16 வயதான அவர் பலரும் வியக்கும் வண்ணம் போராடினார். காந்தியுடன் சிறை சென்றார். சிறையினில் நோய் ஏற்பட்டு 1914ல் இன்னுயிர் நீத்தார்.

தேசியக் கவி பாரதியார்:
தமிழ் வளர்த்து சுதந்திரக் கனல் வளர்த்த எட்டையபுரக்கவி,

“ஒன்றுபட்டால் உண்டு வாழ்வு – நம்மில்
ஒற்றுமை நீங்கில் அனைவர்க்கும் தாழ்வு” (- என )

மொழிந்து 30 கோடி மக்களை ஒன்றாக்கிய பாரதியாரைத் ‘தேசியக் கவி’ என்று அழைப்பதைவிட வேறு எங்ஙனம் அழைப்பதுவோ! சுதேசமித்திரன், இந்தியா போன்ற நாளிதழ்களில் பணியாற்றி மக்களிடையே விடுதலை உணர்வை வளர்த்தார். சிறைவாசங்கள் அவரை சினப்படுத்தியதே அல்லாமல் சாந்தப்படுத்தவில்லை. தம் உணர்வுகளை எல்லாம் பாலாக கிண்ணத்தில் வழங்கிய கவி தன் 39வது வயதில் கோயில் யானை தாக்கியதால் காயம் ஏற்பட்டு இறந்தார்.

திருப்பூர்க் குமரன்:
அறப்போராட்டத்தில் நமது துணிவு கண்டுதான் ஆங்கிலேயன் அச்சம் கொண்டான். அத்துணிவிற்கு ஓர் எடுத்துக்காட்டுதான் கொடிகாத்த குமரன். திருப்பூர் அவரது பிறப்பிடமாகும். காந்தியடிகள் கைதானதை (1932) எதிர்த்து திருப்பூரில் தொண்டர் படைக்குத் தலைமை தாங்கிச்.

செல்லும்போது ஆங்கிலேயர் எடுத்த எடுப்பிலேயே தடியால் தாக்கினர். தலையில் பலத்த அடி. இரத்தம் பெருகலாயிற்று. குமரன் மனம் தளராது கொடியினைப் பிடித்து நின்றார். மயக்கம் வரும்போதும் கொடியைத் தவறவிடவில்லை. மருத்துவமனைக்குக் கொண்டு சென்று சிகிச்சையளித்தும் பயனில்லாமல் உயிர் நீத்தார்.

Question 35.
What is urbanization? Explain its impacts.
Answer:
The process of society’s transformation from rural to urban is known as urbanization. The level of urbanization of a place is assessed based on the size of population of the towns and cities and the proportion of population engaged in non agricultural sectors. These two are closely linked to the process of industrialization and expansion of the secondary and tertiary sectors of economy.

Impacts of urbanization:

Urbanization and population concentration go hand – in – hand and are closely related to
each other. A rapid rate of urbanization in a society is taken as an indicator of its economic development. ‘
Urbanization is increasing rapidly in the developing countries including India.
Rural to urban migration leads to population explosion in urban areas. Metropolitan cities like Mumbai, Kolkatta and Delhi have more population than that can accommodate.

The following are the major problem of urbanization in India:

It creates urban sprawl.
It makes overcrowding in urban centres.
It leads to shortage of houses in urban areas.
It leads to the formation of slums.
It increases traffic congestion in cities. ‘
It creates water scarcity in cities. ,
It creates drainage problems.
It poses the problem of solid waste management.
It increases the rate of crime.

Question 36.
Explain the characteristic features of summer and winter seasons of Tamil Nadu.
Answer:

Summer Seasons:

The apparent migration of the sun towards north during March, April and May results in the reception of vertical sun’s rays by South India. Thus there is a steady rise in temperature from the equator.
Hence, Tamil Nadu located to the south of Tropic of Cancer, experiences high temperature. Generally the temperature varies from 30°C to more than 40°C.
During this season particularly in the month of May, southern part of the state receives some rainfall from pre-monsoon showers (Mango/Blossom showers) and some parts experience convectional rainfall.

Winter Seasons:

During January and F ebruary, the vertical ray s of the sun fal 1 between the Tropic of Capricorn and the Equator. Hence, Tamil Nadu and India on the whole receive slanting rays from the sun. So, the weather is slightly cooler during these months.
The difference between summer and winter temperature is not very high. Winter temperature in Tamil Nadu varies from 15°C to 25°C. However, in the hill stations, the winter temperature drops below 5°C occasionally.
Some valleys in the Nilgiris record even 0°C. This drop in temperature leads to the formation of thick mist and frost. This season is practically dry.

Question 37.
Explain the Jurisdiction and powers of the Supreme Court of India.
Answer:
The Supreme Court is the guardian of the constitution. He performs the following functions.

1. Original Jurisdiction :- The cases which are brought directly in the first instance to the Supreme Court come under original jurisdiction. These may be – (a) dispute between the government of India and one or more States, (b) dispute between two or more States and (c) the cases involving fundamental rights come under the jurisdiction of the Supreme Court.

2. Appellate Jurisdiction :- The Supreme Court is the final appellate Court in the country. It hears appeals against the decisions of High Court in “civil, criminal and constitutional” cases with a certificate from the High Court that it is fit to appeal in the Supreme Court.

3. Advisory Jurisdiction :- The Constitution confers on the President the power to refer to the Supreme Court any question of law or fact which in his opinion is of public importance.

4. The Law declared by the Supreme Court is binding on all courts within the territory of India.

5. The Supreme Court also enjoys the power of judicial review.

Question 38.

To promote the technological information exchange among the member states.
To enhance inclusive economic growth that will lead to an increase in the creation of jobs, fight against poverty and accelerate the economic transformation of members.

Question 39.
Write about the composition of GDP in India.
Answer:
Indian economy is broadly divided into three sectors which contribute to the GDP –

Primary Sector – It includes agriculture based allied activities, production of raw materials such as cattle farm, fishing, mining, forestry etc. It is also called agricultural sector.
Secondary Sectqr – It includes industries that produce a finished, usable product or are involved in construction. This sector generally takes the output of the primary sector and manufactures finished goods. It is also called industrial sector.
Tertiary Sector – It is known as service sector and includes transport, insurance, banking, trade, education, health care etc.

Question 40.
Elaborate the Public Distribution System.
Answer:

1. The increase in food grain production need not result in increase in access to food for all. Given the unequal distribution of income and the level of poverty that persists in Indian economy, the government took steps to distribute food grains at subsidised rates through the Public Distribution System (PDS).

2. The nature, scope and functioning of PDS varies from state to state. While Tamil Nadu has adopted an ‘Universal’ PDS, the rest of the states in India had a ‘Targeted’ PDS. Under universal PDS all the family ration card holders are entitled to the supplies from PDS.

Question 2.
What is the role of the earth wire in domestic circuits?
Answer:

The earth wire provides a low resistance path to the electric current.
The earth wire sends the current from the body of the appliance to the Earth, whenever a live wire accidentally touches the body of the metallic electric appliance.
Thus, the earth wire serves as a protective conductor, which saves us from electric shocks.

Question 3.
State Ohm’s law.
Answer:
According to Ohm’s law, at a constant temperature, the steady current ‘I’ flowing through a conductor is directly proportional to the potential difference ‘V’ between the two ends of the conductor.
I ∝ V. Hence, = \(\frac{1}{V}\) = constant.
The value of this proportionality constant is found to \(\frac{1}{R}\)
Therefore, I = (\(\frac{1}{R}\)) V
V = IR

Answer:
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 3

Question 5.
What connection is used in domestic appliances and why?
Answer:

In the domestic appliance, it is used as a parallel connection to avoid short circuit and breakage.
It has an alternative current (AC). Not DC current as it is from cables, so high potential flows through this.
One more advantage of the parallel connection of circuits is that each electric appliance gets an equal voltage.

VIII. Long answer Questions.

Question 1.
With the help of a circuit diagram derive the formula for the resultant resistance of three resistances connected:
(a) in series and
(b) in parallel
Answer:
(a) Resistors in series : A series circuit connects the components one after the other to form a ‘single loop’. A series circuit has only one loop through which current can pass. If the circuit is interrupted at any point in the loop, no current can pass through the circuit and hence no electric appliances connected in the circuit will work. Series circuits are commonly used in devices such as flashlights. Thus, if resistors are connected end to end, so that the same current passes through each of them, then they are said to be connected in series.
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 4
Let, three resistances R₁, R₂ and R₃ be connected in series. Let the current flowing through theorem be I. According to Ohm’s Law, the potential differences V₁,V₂ and V₃ across R₁, R₂ and R₃ respectively, are given by:
V₁ = I R₁ ………. (1)
V₂ = I R₂ ……… (2)
v₃ = I R₃ ………. (3)
The sum of the potential differences across the ends of each resistor is given by:
V = V₁ + V₂ + V₃
Using equations (1), (2) and (3), we get
V = I R₁ + I R₂ + I R₃ …….. (4)
The effective resistor is a single resistor, which can replace the resistors effectively, so as to allow the same current through the electric circuit. Let, the effective resistance of the series-combination of the resistors, be R_S.
Then,
V = I R_S ……….(5)
Combining equations (4) and (5), we get,
I R_S = I R₁ + I R₂ + I R₃
R_S = R₁ + R₂ + R₃ ……….. (6)
Thus, you can understand that when a number of resistors are connected in series, their equivalent resistance or effective resistance is equal to the sum of the individual resistances. When ‘n’ resistors of equal resistance R are connected in series, the equivalent resistance is ‘n R’.
i.e., R_S = n R
The equivalent resistance in a series combination is greater than the highest of the individual resistances.

(b) Resistors in Parallel : A parallel circuit has two or more loops through which current can pass. If the circuit is disconnected in one of the loops, the current can still pass through the other loop(s). The wiring in a house consists of parallel circuits.
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 5
Consider that three resistors R₁, R₂ and R₃ are connected across two common points A and B The potential difference across each resistance is the same and equal to the potential difference between A and B. This is me sured using the voltmeter. The current I arriving at A divides into three branches I₁, I₂ and I₃ passing through R₁, R₂ and R₃ respectively.
According to the Ohm’s law, you have,
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 6
The total current through the circuit is given by
I = I₁ + I₂ + I₃
Using equations (1), (2) and (3), you get
I = \(\frac{V}{R_1}\) + \(\frac{V}{R_2}\) + \(\frac{V}{R_3}\) ……… (4)
Let the effective resistance of the parallel combination of resistors be R_P Then,
I = \(\frac{V}{R_P}\) ……… (5)
Combining equations (4) and (5), you have
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 7
Thus, when a number of resistors are connected in parallel, the sum of the reciprocals of the individual resistances is equal to the reciprocal of the effective or equivalent resistance. When ‘n’ resistors of equal resistances R are connected in parallel, the equivalent resistance is \(\frac{R}{n}\)
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 8
The equivalent resistance in a parallel combination is less than the lowest of the individual resistances.

Question 2.
(a) What is meant by electric current? Give its direction?
(b) Name and define its unit.
(c) Which instrument is used to measure the electric current? How should it be r connected in a circuit?
Answer:
(a) (i) Electric current is often termed as ‘current’ and it is represented by the symbol ‘I’. It is defined as the rate of flow of charges in a conductor.
(ii) The electric current represents the number of charges flowing in any cross-section of a conductor (say a metal wire) in unit time.

(b) The SI unit of electric current is ampere (A).
The current flowing through a conductor is said to be one ampere, when a charge of one coulomb flows across any cross-section of a conductor, in one second. Hence,
1 ampere = \(\frac{1 \text { coulomb }}{1 \text { second }}\)

(c) (i) The ammeter is used to measure the current.
(ii) An Ammeter is connected in series with the circuit.
(iii) The Ammeter is a low impedance device connecting it in parallel with the circuit would cause a short circuit, damaging the Ammeter or the circuit.

Question 3.
(a) State Joule’s law of heating.
(b) An alloy of nickel and chromium is used as the heating element. Why?
(c) How does a fuse wire protect electrical appliances?
Answer:
(a) Joule’s law of heating states that the heat produced in any resistor is:

directly proportional to the square of the current passing through the resistor.
directly proportional to the resistance of the resistor.
directly proportional to the time for which the current is passing through the resistor.

(b) Because,

It has high resistivity,
It has a high melting point,
It is not easily oxidized.

(c) When a large current passes through the circuit, the fuse wire melts due to Joule’s heating effect and hence the circuit gets disconnected. Therefore, the circuit and the electric appliances are saved from any damage.

Question 4.
Explain about domestic electric circuits, (circuit diagram not required)
Answer:

Electricity is distributed through the domestic electric circuits wired by the electricians.

IX. Numerical problems.

Question 1.
An electric iron consumes energy at the rate of 420 W when heating is at the maximum rate and 180 W when heating is at the minimum rate. The applied voltage is 220 V. What is the current in each case?
Answer:
(i) When heating is maximum, the power
P₁ = 420 W
Applied voltage V = 220 V
P = VI
Current I = \(\frac{P}{V}\)
I = \(\frac{420}{220}\) = 1.909 A
I = 1.909 A

(ii) When heating is minimum
Power P₂ = 180 W
Applied voltage V = 220 V
P = VI
∴ Current I = \(\frac{P}{V}\)
I = \(\frac{180}{220}\) = 0.8181 A
I = 0.8181 A

Question 2.
A 100-watt electric bulb is used for 5 hours daily and four 60 watt bulbs are used for 5 hours daily. Calculate the energy consumed (in kWh) in the month of January.
Solution:
100 W = 100 joules per second
1 watt hours = 3600 joules
The electric bulb is lighted for 5 hours daily,
100 W × 5 = 500 watt hours
500 watt hours = 1800000 joules
1 kWh = 3600000 joules
Units consumed per day = \(\frac{1800000}{3600000}\) = 0.5 units
Untis consumed in month = 0.5 × 31 = 15.5 units …. (1)
Now, Sum of power of four 60 watt bulbs = 240 W
240 W × 5 hours = 1200 watt hours
1200 watt hours = 4320000 joules
Energy consumed per day = \(\frac{4320000}{3600000}\) = 1.2 units
Energy consumed in a month = 1.2 × 31 = 37.2 units …. (2)
Total energy consumed in a month = 15.5 + 37.2 = 52.7 units
1 unit = 1 kWh
The energy consumed in the month of January = 52.7 kWh.

Question 3.
A torch bulb is rated at 3 V and 600 mA. Calculate it’s
(a) power
(b) resistance
(c) energy consumed if it is used for 4 hour.
Answer:
Voltage V = 3 V
Current I = 600 mA
(a) Power = VI
= 3 × 600 × 10^-3
= 1800 × 10^-3
= 1.8 W
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 9
(c) Time = 4h
Energy consumed E = P × t
E = 1.8 × 4
= 7.2 W

Question 4.
A piece of wire having a resistance R is cut into five equal parts.
(a) How will the resistance of each part of the wire change compared with the original resistance?
(b) If the five parts of the wire are placed in parallel, how will the resistance of the combination change?
(c) What will be ratio of the effective resistance in series connection to that of the parallel connection?
Answer:
(a) Original resistance
R = \(\frac{l}{A}\)
∴ R α l
After cutting length of each piece
r = \(\frac{l}{5}\)
New resistance
R’ = \(\frac{l’}{A}\)
R’ α l’
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 10
R : R’ = 5 : 1

(b) When five parts of the wire are placed in parallel.
Effective Resistance
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 11
Resistance of the combinations
R_P = \(\frac{R}{25}\)

(c) When resistance are connected in series

R_S = R
When resistance are connected in parallel
R_P = \(\frac{R}{25}\)
R_S : R_P = R : \(\frac{R}{25}\)
= 25 R : R_1
R_S : R_P = 25 : 1

X. HOT Questions.

Question 1.
Two resistors when connected in parallel give the resultant resistance of 2 ohm; but when connected in series the effective resistance becomes 9 ohm. Calculate the value of each resistance.
Answer:
Let the resistance be R, and R2 when two resistances are connected in series
R_S = R₁ + R₂
= 9
R₁ + R₂ = 9 ……….(1)
When two resistance are connected in parallel
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 13
Using (1) equation (2) becomes
\(\frac{9}{R_{1}R_2}\)
R₁ R₂ = 18 ……….(3)
(R₁ – R₂)² = (R₁ + R₂)² – 4R₁R₂
= (9)² – 4 × 18
= 81 – 72 = 9
∴ (R₁ – R₂) = √9 = 3 ………(4)
From (1)
R₁ + R₂ = 9
2R₁ = 12
∴ R₁ = \(\frac{12}{2}\) = 6 ohm
From (1)
R₂ = 9 – R₁
= 9 – 6 = 3Ω
The values of resistances are
R₁ = 6 ohm
R₂ = 3 ohm

Question 2.
How many electrons are passing per second in a circuit in which there is a current of 5 A?
Solution:
Current I = 5A
Time (t) = 1 second
Charge of electron e = 1.6 × 10^-19 C
\(\mathbf{I}=\frac{q}{t}=\frac{n e}{t}\)
Number of electron, n = \(\frac{\mathrm{I} t}{e}\) = \(\frac{5 \times 1}{1.6 \times 10^{-19}}\)
n = 3.125 × 10¹⁹.

Question 3.
A piece of wire of resistance 10 ohm is drawn out so that its length is increased to three times its original length. Calculate the new resistance.
Answer:
Resistance R = 10Ω
Let l be the length of the wire R ∝ 1
When the length is increased to three times,
l’ = 3l
∴ New Resistance
R’ ∝ l’ ∝ 3l
∴ \(\frac{R}{R’}\) = \(\frac{l}{3l}\) = \(\frac{1}{3}\)
∴ R’ = 3R
New resistance = 3 times the original resistance.

Question 2.
Explain series connection of parallel resistors.
Answer:
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 30
If we consider the connection of a set of parallel resistors that are connected in series, you get a series – parallel circuit. Let R₁ and R₂ be connected in parallel to give an effective resistance of R_p1. Similarly, let R₃, and R₄ be connected in parallel to give an effective resistance of R_p2. Then, both of these parallel segments are connected in series. Using equation we get
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 31
We get = R₁ + R₂ + R₃ ……….(1)
Finally, using equation (1), the net effective resistance is given by
R_total = R_P1 + R_P2

Question 3.
Explain parallel connection of series resistors.
Answer:
If you consider a connection of a set of series resistors connected in a parallel circuit, you get a parallel-series circuit. Let R₁ and R₂ be connected in series to give an effective resistance of R_S1. Similarly, let R₃ and R₄ be connected in series to give an effective resistance of R_S2. Then, both of these serial segments are connected in parallel.
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 32
Using equation
R_S = R₁ + R₂ + R₃
We get R_S1 = R₁ + R₂, R_S2 = R₃ + R₄
Finally, using equation
\(\frac{1}{R_P}\) = \(\frac{1}{R_1}\) + \(\frac{1}{R_2}\) + \(\frac{1}{R_3}\)
the net effective resistance is given by
\(\frac{1}{R_{total}}\) = \(\frac{1}{R_{S1}}\) + \(\frac{1}{R_{S2}}\)

Question 4.

Answer:
Electric Heating Device: The heating effect of electric current is used in many home appliances such as electric iron, electric toaster, electric oven, electric heater, geyser, etc. In these appliances Nichrome, which is an alloy of Nickel and Chromium is used as the heating element. Because:
(i) it has high resistivity,
(ii) it has a highmelting point,
(Hi) it is not easily oxidized.

Fuse Wire : The fuse wire is connected in series, in an electric circuit. When a large current passes through the circuit, the fuse wire melts due to Joule’s heating effect and hence the circuit gets disconnected. Therefore, the circuit and the electric appliances are saved from any damage. The fuse wire is made up of a material whose melting point is relatively low.

Filament in bulbs : In electric bulbs, a small wire is used, known as filament. The filament is made up of a material whose melting point is very high. When current passes through this wire, heat is produced in the filament. When the filament is heated, it glows and gives out light. Tungsten is the commonly used material to make the filament in bulbs.

Question 12.
Two bulbs of 40 W and 60 W are connected in series to an external potential difference. Which bulb will glow brighter? Why?
Answer:
Let the external potential difference be 230 V
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 48
For 40 W bulb resistance is R

For 60 W bulb resistance is R

According to Ohm’s law
I = \(\frac{V}{R}\)
Current flowing through 40 W bulb is
\(\frac{230}{1322.5}\) = 0.1739 A
Current flowing through 60 W bulb is
\(\frac{230}{881.6}\) = 0.2608 A
When bulbs are connected in series effective resistance is
R_S = R₁+ R₂ = 1322.5 + 881.6
R_S = 2204.1Ω
Net current
I = \(\frac{230}{2204.1}\) = 0.1043 A
Using power equation P = I²R
For 40 W bulb P = I²R
= (0.1043)² × 1322.5
= (0.01087) × 1322.5 = 14.386 W
For 60 W bulb P = I²R
= (0.1043)² × 881.6
= (0.01087) × 881.6 = 9.5904 W
In a series system, higher the resistance, higher the brightness so, 40 W bulb glows brighter.

Question 13.

R = 16Ω
x is the resistance of the wire.
x = 16 + 16 = 32Ω
x = 32Ω

X. HOT Questions.

Question 1.
A 60 W bulb is connected in parallel with a room heater. This combination is connected across the mains. If 60 W bulb is replaced by a 100 W bulb what happens to the heat produced by the heater? Given reason.
Answer:
Heat produced by the heater will be same. When the bulb and a heater are connected in parallel and this combination is connected across the mains, potential difference across each is the same equal to the voltage V of the mains irrespective of the resistance of the bulb.

If R is the resistance of the heater then heat produced by the heater will be \(\frac{V^2}{R}\) in both cases. Hence heat produces by heater will not be changed.

Question 2.
Two bulbs 60 W and 100 W are connected in series and this combination is connected to a d.c power supply. Will the potential difference across 60 W bulb be higher than that across 100 W bulb?
Answer:
60 W bulb has a higher resistance than the resistance across 100 W bulb since the power developed is P = \(\frac{V^2}{R}\).
Potential difference across a bulb will be proportional to resistance. Hence potential difference across 60 W bulb is higher than that across 100 W bulb.

Question 3.
Super conductors has lowest resistance. Is it true. Give reason.
Answer:
True. When the temperature of super conductor is reduced to zero or near by zero its resistance becomes zero.

Question 4.
A constant voltage is applied between two ends of a uniform conducting wire. If both the length and radius of the wire is doubled then what happens to the heat produced in the wire?
Answer:
We know that resistance of a conducting wire is R = \(\frac{pl}{A}\)
\(\frac{Pl}{πr^{2}}\)
If length l and radius r are doubled, then resistance will become half. But heat produced H = \(\frac{V^2}{R}\).
Hence, heat produced per second will become thrice.

Question 5.
Calculate the effective resistance between A and B.
Answer:
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 51
The electrical circuit can be redrawn as

The resistance R₁ and R₂ are in series
R_S = R₁ + R₂ = 2 + 2 = 4Ω
The resistance R_S and R₃ are in parallel

∴ Effective resistance R_eff= 1.33Ω

Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 54
∴ r₁ : r₂ = √2 : 1

Question 7.
An iron box of 400 W power is used daily for 30 minutes. If the cost per unit is 75 paise, find the weekly expense on using the iron box.
Answer:
Power P = 400 W
Samacheer Kalvi 10th Science Guide Chapter 4 Electricity 55
Energy consumed = Power × Time
= 400 × \(\frac{1}{2}\) = 200 Wh
Energy consumed in one week= 200 × 7
= 1400 Wh = 1.4 kWh
= 1.4 unit
∴ Total cost per week = 1.4 × 0.75 = Rs 1.05
Weekly expense = Rs 1.05

What do you know about James Thurber, the narrator?
Answer:
The narrator James Thurber, presents himself as acting judiciously, although his actions are uncommon to raise the uncertainties of the policemen. He is the first person in the household to hear the mysterious sound, as he is stepping out of the bathtub at 1:15 a.m. on November 17th. After waking his brother Herman, he is the one who resolves that the reason of the sound downstairs must be an apparition. When his hasty mother decides that the sounds must be caused by intruders, the narrator thinks that she is past reasoning. Even when the cops arrive, he is still wrapped in a towel from his bath.

Later, when the reporter comes around asking questions, the narrator puts on one of his mother’s blouses, explaining that it is the only thing that he can find at the moment. He chooses to be honest with the reporter and tell him that the problem was caused by ghosts, but the reporter does not take him earnestly. Later, when the policeman who has been shot by Grandfather wants to challenge him and take his gun back, the narrator mediates with composed receptivity and offers to take the gun over to the police station in the morning.
“A judicious reticence is hard to learn, but
it is a lifetime lesson.’’

‘Man does change with time’-What were the various changes that came about in Aditya?
Answer:
Man does change with time. According to Sanyal, Aditya was a boy who could never compete him in scholastic or non-scholastic activities. He was a liar and an envious personality. But, years later Aditya no longer is the same personality. He is more matured and responsible. His childish nature makes him feel guilty, for stealing the medal that belonged to Sanyal.

Aditya now wanted to restore Sanyal, his lost happiness. Knowing about his financial constraints, he decides to give him the cost of the silver medal. He drives with a firm determination to his ancestral house. When he reaches, he rushes to the attic. Aditya gets on top of a packing Case and pushes his hand inside the ventilator, upsetting a sparrow’s nest. However, he heaves a sigh of relief when he gets what he had been looking for. He goes straight to the Jeweller to determine the current rate of the medal in the market. All these surely show a remarkable change in him.

Even when Sanyal behaves rudely, Aditya is courteous and friendly. His only intention is penitence. He is so mature that he even understands and justifies the grievances Sanyal had in his heart. When Sanyal prefers the medal, without second thoughts he restores it to Sanyal whole-heartedly.
“Change is universal.”

Question 33.
Narrate the fable of ‘The Ant and the Cricket’ in your own words.
Answer:
The silly young cricket was fun-loving. He used to sing all through the pleasant sunny months of summer and spring. He was short-sighted. He didn’t bother to store food for the rainy season and cold winter. When the earth was covered with ice and snow, he found that he had nothing to eat and his cupboard was empty. There were no flowers nor leaves on the trees. He grew nervous. Starvation could be seen over his face. Wet with the rain and shivering with cold, the hungry cricket went to an ant to get shelter and food.

He made it clear that he would return the borrowed grain the next day. With humility, the miserly ant said that he was surely the servant and friend of the cricket. But as a matter of principle, the ants neither borrow nor lend. He asked why he never bothered to store something for the rainy day. The cricket admitted that he had been careless and foolish. He enjoyed the beauties of summer and sang merrily. The ant then told him bluntly to go and dance all winter and turned the poor cricket out.
‘Prudence is foresight and farsightedness. ’

Question 34.
The poem ‘No men are foreign’ has a greater relevance in today’s world. Elucidate.
Answer:
The poet, James Kirkup, quotes various instances to prove that no men are foreign. The very title of the poem is thought-provoking and forces the reader to think about the issue of people living in other countries as foreigners and strangers. As the poem advances, the poet recurrently emphasises that all human beings are indistinguishable in their nature and tactics. All live on the same earth; enjoy air, sun and water; love peace and are opposed to war.

They all have mutual experiences and toil in a similar manner to earn the living. The realistic reasoning put forth by the poet and the numerous reminders fully satisfy the reader that no men are foreign. He gets the message that alienation from fellow brethren is equally damaging to himself. He also understands that by treating other men as foreign, the world stands exposed to the risk of war which can lead to permanent destruction and pollution of mother earth. It is true that many people have been telling us to live harmoniously since long. We never follow their message.

We also know that our greed to get more wealth and power cannot give us peaceful life. But some deep-rooted evils in our society make us draw a distinction between people. We know that all customs and conventions have been made by people. We start to hate even our family members due to our ego to be more powerful. By doing so, we at last harm ourselves. In society, people dislike selfish people. So before going to hurt other’s feeling, first of all we should think whether doing such act with others are justified by other people or society.
‘Smile at strangers and you just might change a life. ’

Question 35.

(ii) What is the figure of speech used in the second line?

(ii) The figure of speech is alliteration, (e.g. forward face)
(iii) Year and disappear; soul and goal are the rhyming words.
(iv) With forward face and unreluctant soul;

Question 36.
Paraphrase the following stanza.
Some water, coal, and oil is all we ask,
And a thousandth of an inch to give us play:
And now, if you will set us to our task,
We will serve you four and twenty hours a day!
Answer:
Here it is clearly stated that the only requirement for the machine is water, coal and oil. The moving parts may have a clearance of a thousandth of an inch which may be the permissible variation from the required dimensions. These parts are closely arranged with bolts and nuts leaving only less than an inch for the movement of wheels. With such a setup, the machines are willing to work round the clock, non-stop without any rest.

From that gallery a thousand projectors were unceasingly employed in sending to the clouds, on which they were reproduced in colour, these inordinate advertisements. At that moment the clock struck twelve. The director of the Earth Herald left the hall and sat down in a rolling armchair. In a few minutes he had reached his dining room half a mile away, at the far end of the office. The table was laid and he took his place at it.

Within reach of his hand was placed a series of taps and before him was the curved surface of a phonotelephote, on which appeared the dining room of his home in Paris.

Sir,
Sub: Poor sanitary conditions and mosquito menace in Periyar Road I want to draw your kind attention towards the poor sanitary conditions prevailing in our locality – Periyar Road. It seems that the cleaners have forgotten the existence of this locality on the civic map of Chennai. Heaps of rubbish are lying here and there, with flies swarming around and pigs wallowing in the filth and mud caused by the overflow of dirty water from the drains on to the road. The drains are choked as they are neither cleaned nor flushed.

The dirty water collects on the road forming cesspools of filthy water. There are also many pits on the roads which are full of drain water. All these serve as breeding places for mosquitoes. The mosquito menace is so intense in our locality that we have to use anti mosquito sprays, mats and repellants have undisturbed sleep for a couple of hours. You are requested to pay
a surprise visit to the locality and judge the state yourself. Kindly take some immediate and effective steps to improve the sanitation and rid us of the menace of mosquitoes.

Hoping for a favourable action.
Yours faithfully

Question 46.
(a) Love of a son for his mother – opposition to the law – tyrant – elderly people inefficient – importance of aged people – decree. Foothills – proclamation – cruel decree – killing aged people wasn’t common – poor farmer distressed.
Answer:
“The Aged Mother” by Matsuo Basho is a Japanese folklore about the love of a son for his mother and the mother’s love in return for her son. They encountered this agony as an opposition to the law of placing aged people to death. The tyrant stated the law of killing the elderly people because he was a warrior himself who felt that only the young men and women who were robust were useful to the country. According to the warrior, elderly people were inefficient and couldn’t be obliging to individuals who were however healthy as him.

To such a despotic leader, the importance of aged people was insignificant. Hence, he pronounced it as a decree. When the poor farmer and his aged mother who lived in a poor hut of the foothills in the country of Shining heard the proclamation by the despotic leader who announced the cruel decree of killing elderly people in that place, their heart was distressed. During this period, killing aged people wasn’t common. Therefore, when the poor farmer came to know of the decree he bore sadness in his heart. He was extremely concerned and was in deep thoughts to make an escape.

Answer:
Dr. Ashok T Krishnan’s family shelters Somu’s new pet, Zig-Zag, a queer-looking African bird, who is known for talking and singing in twenty-one different languages. They consider Zigzag to be a harmless, unusual and lovable bird bred by a genuine African witch doctor, who gifted it to Somu when he toured the deepest jungles of Africa. To Somu, the bird is an absolute treasure and a real help. Mrs. Krishnan considers it a nuisance.

Their son Arvind and daughter Maya are keen on having the pet. They both discuss the unique gifts given by Uncle Somu viz insect-eating plant, tiny shark teeth penknife and the aboriginal boomerang. ZigZag turns out to be a disappointment for the Krishnan family. Zigzag does nothing but sleep and snore to annoy all around. All attempts to awaken the bird goes in vain. The bird at first before resorting to a steadfast sleep eats the nuts and fruits, keeps them safe in the chandelier and the fan blades.

The maid Lakshmi shrieks in an excited manner thinking she is blessed with papayas and bananas raining inside the room. Mrs. Krishnan is annoyed at the slice of overripe papaya whizzing off the fan and splattering all over her unfinished masterpiece – Sunset at Marina spreading streaks of gooey orange pulp and shiny black seeds all over it. Dr. Krishnan leaves an e-mail message for Somu, asking him for clear instructions on how to stop Zigzag from snoring. On the seventh day, they receive the reply that he never sleeps nor snores. Mrs. Krishnan wants it to be sent to Visu as her friends and experts will come home and choose her paintings for the exhibition. Krishnan takes ZigZag in the car and hopes to find Visu so that ZigZag’s snore doesn’t add to the din of the sobs and shrieks produced by the tiny patients waiting for him.

However, Ziggy-Zagga, King-of-the-Tonga, was not familiar to being kept waiting, makes his way to the clinic where he perches himself on the nurse’s reception table. Suddenly things take a turn when ZigZag starts speaking. It’s Zigzag’s voice, clear and commanding. Gone was Zigzag’s bored and grumpy expression. Instead, the bird looked happy and alert as it went about the job it had been trained for, first with the African witch doctor and then with Dr. Somu.

Question 47.
Read the following passage and answer the questions given below:
Answer:
Rambutan is a close cousin of the litchi fruit, but not as well known. It is a member of the Sapindaceae family and resembles the litchi, except for its long, flesh coloured spines. Rambutan (Napheluim lappaceum) is an ever green tropical tree which reaches a height of 50 to 80 feet and has a straight trunk, with a dense spreading crown. There are both male and female trees and only female trees bear fruit. It grows best in deep, clay loam or sandy loam rich in organic matter.

Rambutan is usually propagated by seeds. The seeds taken from the fruit, may be planted horizontally with the flattened side downward so that the seeding grows straight and has a strong root system. While harvesting the entire fruit cluster must be cut from the branch. The fruit must be kept dry and well ventilated to prevent them from getting spoilt. The peeled fruits are occasionally stewed as dessert.

Questions.
(a) Which fruit does the Rambutan look like?

Read the following poem and answer the questions given below:
All are over: does truth sound bitter As one at first believes?
Mark, ‘tis the sparrow’s good night twitter About our cottage eaves?
And the leaf-buds on the vine are woolly,
I noticed that, today;
One day more bursts them open fully You know the red turns grey.
Tomorrow we meet the same then, dearest?
May I take your hand in mine?
Mere friends are we — well, friends the merest Keep much that I resign:
For each glance of the eye so bright and black,
Though I keep with heart’s endeavour, —
Your voice, when you wish the snowdrops back,
Though it stays in my soul forever!
Yet I will but say what mere friends say,
Or only a thought stronger.
I will hold your hand but as long as all may,
Or so very little longer.
