A boy standing between two cliffs claps and hears 2 echoes after 2 sand 2.5 s respectively . If the velocity of-sound is 330 `ms^-1` , find the distance between the two cliffs.

Text Solution

AI Generated Solution

To solve the problem, we need to find the distance between the two cliffs based on the time taken for the echoes to return to the boy after he claps. ### Step-by-step Solution: 1. **Understanding the Echoes**: - The boy hears two echoes after 2 seconds and 2.5 seconds. - The first echo (T1) takes 2 seconds to return, and the second echo (T2) takes 2.5 seconds. ...
