1.	Can u help me find this answer?1)Velocity of sound in the atmosphere of a planet is 500ms^-1.The minimum distance between the source and sound and the obstate to hear the echo,should bea)17mb)20mc)25md)50m
Answer» Answer: EXPLANATION: Given, SPEED of sound = 500m/s Therefore the distance transversed by sound wave in one SECOND = 500m So, the distnace transversed by the sound wave in 1/10 sec =50.0m Since the sound wave has to travel the distance between source nd reflector twice to produce ECHO. So the minimum distance between source nd reflector required to produce echo = 50.0/2 = 25m

Answer»

Answer:

Given,

SPEED of sound = 500m/s

Therefore the distance transversed by sound wave in one SECOND = 500m

So, the distnace transversed by the sound wave in 1/10 sec =50.0m

Since the sound wave has to travel the distance between source nd reflector twice to produce ECHO. So the minimum distance between source nd reflector required to produce echo = 50.0/2 = 25m
