Question

A person clapped his hands<br />near a cliff and heard the echo after 2 s<br />What is the distance of the cliff from the<br />person if the speed of the sound, v is<br />taken as 346 m s-l?​

Answer 1

Answer:

Explanation:

speed of sound is 346 m

time taken to hear a echo is 2s

therefore distance between the cliff and the person is 2d

speed=distance /time

distance=speed *time

=2d=346*2

=d=346*2/2

=346m

therefore the distance=346 m
