Question

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

Answer 1

Answer:

Explanation:

speed of the sound is 246 m/s

time taken to hear echo is 2s

therefore distance travelled by sound is 2d

speed=distance/time

distance=speed*time

=2d=346*2

=d=346*2/2=346m

therefore distance between the person and the cliff is 346m
