(a) Only pendulum C will start vibrating.

(b) Pendulums A, B, and D will also start vibrating but A and D will vibrate with the maximum amplitude.

(c) Pendulums A, B, and D will also start vibrating.

(d) Vibrations of pendulum C are forced vibrations.

Answer : (b) Pendulums A, B, and D will also start vibrating but A and D will vibrate with the maximum amplitude.

Reason:- due to resonance

Answer : option (a)

(vi) The meaning of the statement ‘Specific heat capacity of water is 4200 Jkg-¹K-¹ ’ is:

(a) Water needs 4200 J heat to raise its temperature by 1 kelvin.

(b) To raise the temperature of water 4200 J of heat is absorbed.

(c) 1 kg water absorbs 4200J heat to increase its temperature by 1 kelvin.

(d) 1 kg Water needs 1 kelvin temperature to absorb 4200 J heat.

Answer :(c) 1 kg water absorbs 4200J heat to increase its temperature by 1 kelvin.

(vii) 200 g of ice at 0ºC needs _________ heat to melt. [Specific latent heat of ice = 336000 J kg-¹]

(a) 6720 J

(b) 67200 J

(c) 672000 J
