Question 1:

(a) Name the device used for measuring :
(i) mass
(ii) weight.  [2]

(b) A body weighs 360 N on the earth :
(i) What would be his approximate weight on the moon ?
(ii) What is the reason for your answer ?  [2]

(c) A body is acted upon by a force. State two conditions under which the work done could be zero. [2]

(d) A spring is kept compressed by a small trolley of mass 0.5 kg lying on a smooth horizontal surface as shown in the figure given below :
icse-previous-papers-solutions-class-10-physics-2010-1When the trolley is released, it is found to move at a speed of 2 ms-1[2]

 (e) Name the subjective property :

(i) of sound related to its frequency.
(ii) of light related to its wavelength. [2]

(ii) What is the cause of refraction of light ?  [2]


(c) ‘The refractive index of diamond is 2.42’.
What is meant by this statement ? [2]

(d) We can bum a piece of paper by focusing the sun rays by using of lens.
(i) Name the type of lens used for the above purpose.
(ii) Draw a ray diagram to support your answer.

(e) A ray of light enters a glass slab PQRS, as shown in the diagram. The critical angle of the glass is 42°. Copy this diagram and complete the path of the ray till it emerges from the glass slab.
icse-previous-papers-solutions-class-10-physics-2010-3Mark the angles in the diagram wherever necessary.  [2]


(a) (i) ∴    Effort arm > Load arm.
(ii) Single movable pulley.

(b) (i) The deviation in the path of light when it travels from one medium to the other is called refraction of light.
(ii) Speed of light is different in different mediums.



(c) It means that the ratio of speed of light in air to the speed of light in diamond is 2.42.

(d) (i) Convex lens.


Question 3:

(a) State two differences between light waves and sound waves.  [2]

(ii) What will be the ratio of their frequencies ?  [2]

(c) Give two differences between a d.c. motor and an a.c. generator.  [2]


(d) Six resistances are connected together as shown in the figure. Calculate the equivalent resistance between the points A and B.  [2]

(e) (i) Which part of an electrical appliance is earthed ?
(ii) State a relation between electrical power, resistance and potential difference in an electrical circuit. [2]


(a) Difference between Sound waves and Light waves :

Sound Waves Light Waves
1. These are mechanical waves. They require medium for propagation. 1. These are electromagnetic waves. They can travel in vacuum.
2. These are longitudinal waves. 2. These are transverse waves.

(b) (i) ∴ Loudness ∝ (Amplitude)2
(ii) Frequency remains same if pitch is unchanged. i.e., Ratio of frequencies = 1 : 1

(c) Difference between D.C. motor and A.C. Generator:

D. C. Motor A. C. Generator
(i) It converts Electrical energy into Mechanical energy. (i) It converts Mechanical energy into Electrical energy.
(ii) It consists of split rings. (ii) It consists of slip rings.

(d) The resistance 2Ω, 3Ω and 5Ω are in series. Their equivalent resistance is R’ = 2 + 3 + 5 = 10Ω.
Now the resistance 10Ω and R’ are in parallel. Their equivalent resistance is
icse-previous-papers-solutions-class-10-physics-2010-8 Now 2Ω, R” (= 5Ω) and 5Ω resistances are in series between A and B.
∴ Equivalent resistance between A and B is,
= 2 + 5 + 5 = 12Ω.
