A) In winter
B) In summer
C) In all seasons
D) None of these
Correct Answer: B
Solution :
[b] Time recorded in summer is more accurate. The velocity of sound is directly proportional to the square root of absolute temperature. Hence, the sound of the gun fired at the starting j point will reach the finishing point quicker in summer than j in winter. The lapse of time due to the time taken by the sound in reaching the finish point will be less in summer and hence the time recorded will be more accurate in summer than in winter.
