Philoid · Accepted Answer

Given

Speed of sound (u) = 346 m/s

Time taken for hearing the echo (t) = 4s

Now

⇒

⇒ Distance travelled by the sound = 346 ×4 = 1384 m.

In 4 s, sound has to travel twice the distance between the cliff and aditi. Therefore, the distance between the cliff and aditi is = = 692 m

Distance of cliff from aditi = 692 m

Aditi clapped her hands near a cliff and heard the echo after 4 seconds. What is the distance of the cliff her if the speed of sound is taken as 346 ms-1.
