A) \[10\,\,s\]
B) \[1000\,\,s\]
C) 1 day
D) None of these
Correct Answer: D
Solution :
The radius of moon and acceleration due to gravity at its surface both are smaller compared to earth. Therefore the escape velocity at moon is\[2.38km{{s}^{-1}}\]. At the temperature of moon, the average velocity of gas molecules greater than this. Therefore, gas molecules cannot stay at moon. 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.
