A) 10 s
B) 1000 s
C) 1 day
D) None of these
Correct Answer: D
Solution :
Surface both are smaller compared to earth. Therefore the escape velocity at moon is \[2.38\,\,km{{s}^{-1}}\]. At the temperature of moon, the average velocity of gas molecules greater than this. Therefore, gas molecules cannot stay at moon and escaped out. Hence, there is no atmosphere around the moon. Since, sound waves need a medium for propagation therefore, sound produced by the bomb explosion will never reach the earth.
