Physics sample paper for class X of Andhra Pradesh Board:-

 SECTION – A 

Question 1 VERY SHORT QUESTION ANSWERS ( 10 * 1 = 10 MARKS ) :

a) What type of process is Carnot’s cycle?
ans:- Cyclic process.

b ) Refrigerator transfers heat from a cold body to a hot body. Does this not violate the second law of thermodynamics?
ans:-No. This is because external work is being performed.

c)What happens to the phase of water at its critical point?
ans:-At the critical point, water and water vapours are equally dense.

d ) Give one application of triple point?
ans:-The triple point of a substance is used to define absolute temperature.

e) Give one example of a heat pump.
ans:-Refrigerator is an example of a heat pump.

f ) How is the efficiency of a Carnot engine affected by the nature of the working substance?
ans:-The efficiency is independent of the nature of the working substance.

g) What forbids the complete conversion of work into heat?
ans:-Second law of thermodynamics.

h) We cannot move a ship in a n ocean by utilizing the energy of the ocean. Why?
ans:-This is because no sink is available.

i )What is a heat pump?
ans:-A heart pump is a device which uses mechanical work to remove heat.

j) The door of an operating refrigerator is kept open in a closed room. Will it make the room warm or cool?
ans:-The room will be slightly warmed.

QUESTION-2 SHORT ANSWER QUESTIONS ( 10 * 2 = 20 MARKS ) :

 a ) Can the components of a given vector be greater than the vector itself ?
ans:-The two rectangular components of a vector are R cos X and R sin X, Since, both, sin X and   cos X are always less than one, a component  can never be greater then the vector.

b ) The capillary rise in a tube is 12 cm, when dipped in a given liquid,  Will   the liquid flow continuously from the tip of the tube, if it is broken at a height of 10 cm from the surface  of liquid ? Explain your answer?
ans:-The liquid will not flow.  In case of a tube  of insufficient length, the curvature of the meniscus gets flattened to produce equilibrium.

c) Two cars are moving on a road in the same direction side-by-side and are parallel to each other. Explain why they tend to be pulled towards each other?
ans:-As a result of motion of two cars, the air in between them  possesses a greater velocity then the air on sides, thus producing a low pressure region there.  Therefore, they get pushed towards each other.

d) Define coefficient of thermal conductivity?
ans:-Co-efficient of thermal conductivity of a substance is defined as the quantity of heat which flows , in one second , through the opposite faces of a centimetre cube of the substance whose opposite faces are kept at a temperature difference of 1 degree celcius .

e) Define thermal radiation?
ans:-The energy emitted , in the form of radiation , by a body due to its temperature is called thermal radiation .

f) State Boyle’s law?
ans:-It states that the temperature remaining constant , volume of a given mass of a gas varies inversely at its pressure .

g) State Charle’s law?
ans:-states that pressure remaining constant , volume of a given mass of a gas varies directly as the absolute temperature of the gas .

h) State Grahm’s law of diffusion?
ans:-It states that the rates of diffusion of gasses vary inversely as the square root of their densities.

i)What is ideal gas equation?
ans:-A relation between the pressure , volume and temperature of an ideal gas is called ideal gas equation.

j) Define root mean square speed ?
ans:-It is the square root of the mean of the squares of the individual speeds of the molecules of a gas.

SECTION-B

VERY LONG ANSWER QUESTIONS ( 8 * 5 = 40 MARKS ) :

QUE 1 ) State the law of parallelogram of vectors and derive expressions for the magnitude and the direction of resultant.Three forces, 10 N, 10 N and 30 N are acting simultaneously on a participle towards north, west and east respectively. Find their resultant.
ANS) It states that if two vectors acting simultaneously at a point are represented in magnitude and direction by the two sides of a parallelogram drawn from a point,their resultant is given in magnitude and direction by the diagonal of the parallelogram passing through that point .
Resultant force along OE = ( 30 – 10 ) N = 20 N
R= ((10)^2+(20)^2)^2 = 10 (3)^2
Tan x = 10/20= ½

QUE 2 ) A bullet of mass 0.5 gm strikes a wall with a velocity of 100 m/sec and moves a distance of 0.1 m through the wall to come to rest. Find the resistance offered by the wall.
ANS ) u = 100 m/s , v = 0 , s = 0.1 m , a = ?
(v)^2 –(u)^2 = 2as
0 – 100^2 = 2 x a x 0.1 , hence a = -100/0.2 = (-) 500 m/ s^2
F= ma = -(0.5 / 1000) X 500 N
Or F = 0.25 N

QUE 3 ) Can the components of a given vector be greater than the vector itself ? The capillary rise in a tube is 12 cm, when dipped in a given liquid, Will the liquid flow continuously from the tip of the tube, if it is broken at a height of 10 cm from the surface of liquid ? Explain your answer?
ANS ) The two rectangular components of a vector are R cos X and R sin X, Since, both, sin X and cos X are always less than one, a component can never be greater then the vector.
In case of a tube of insufficient length, the curvature of the meniscus gets flattened to produce equilibrium hence the liquid will not flow when capillary rises to 12 cm.

QUE 4 ) Temperature of certain bath gives the same reading on both the centigrade and Fahrenheit scales. calculate the temperature of both?
ans:-C/100 = (F-32 ) / 180
t/100 =(t-32)/180
t-32=18/10=9t/5
t x –(4/5)=32
t = -32 x (5/4) = -40 degree C.

QUE 5 ) The freezing point of a thermometer is marked 20 and the boiling point as 150 . What reading will this thermometer give for a temperature of 45 degree C?
ans:-Let T = reading on the thermometer .
C/100 = ( t-L.P.F) / ( U.F.P – L.F.P)
45/100 = ( t-20)/(150-20)= (t-20)/130
t-20 = (130/100) x 45 = 58.5
t = 78.5 degree C

QUE 6 ) Two cars are moving on a road in the same direction side-by-side and are parallel to each other. Explain why they tend to be pulled towards each other? Define coefficient of thermal conductivity?
ANS ) As a result of motion of two cars, the air in between them possesses a greater velocity then the air on sides, thus producing a low pressure region there. Therefore, they get pushed towards each other and the co-efficient of thermal conductivity of a substance is defined as the quantity of heat which flows , in one second , through the opposite faces of a centimetre cube of the substance whose opposite faces are kept at a temperature difference of 1 degree Celsius.

QUE 7 ) A body is moving in a circular path with uniform speed. Is the motion simple harmonic ? A streamline flow of a liquid is maintained in a tube. What happens to its velocity of flow in a region, where the area of cross-section is halved ? State the relation between surface tension and surface venery?
ANS ) No, this motion is not simple, harmonic. The, projection of this motion on one of the diameters of the circle will be sample harmonic.
When a streamline flow is maintained in a tube the velocity of liquid is doubled. The relation between surface tension and surface venery is :
Surface energy + T x increase in area .

QUE 8 ) Define strain ? what are the three types of strains ?
ANS ) Relative change in configuration due to the application of deforming forces is called strain . There are three types of strain
a) Longitudinal strain : It is the ratio between change in length to its original length.
Longitudinal strain = l / L
b) Volume strain : It is defined as the ratio between change in volume to its original volume.
Volumetric strain = v / V
c) Shear strain : Shear strain is measured by angle turned by a line originally perpendicular to the fixed face . It can also be defined as the ratio between displacement in one plane to its distance from the fixed plane . It has no unit.
