A man stands before a large wall a large will at a distance of `100.0 m` and claps his hands at regular intervals in such way that echo of a clap marges with the next clap. If he claps `5` times during every `3` seconds, find the velocity of sound in air.

A man stands before a large wall at a distance of 50.0 m and claps his hands at regular intervals. Initially, the interval is large. He gradually reduces the interval and fixes it at a value when the echo of a clap merges with the next clap. If he has to clap 10 times during every 3 seconds, find the velocity of sound in air.

A man claps his hands in front of a wall and he hears the echo after 1.6 s . He walks 33 m nearer the wall and hears the echo 1.4 s after clapping. Find the velocity of sound in air.

A girl stands 170 m away from a high wall and claps her hands at a steady rate so each clap coincides with echo of the one before. (I) If she claps 60 claps in 1 min what value should be the speed of sound in air ?

A man standing in front of mountain at a certain distance beats a drum at regular intervals. The drumming rate is gradually increased and finds that the echo is not heard distinctly when the rate becomes 40 per minute. If the velocity of sound in air is 340 m/s, then the distance between the man and mountain is

A man standing between two parallel hills, claps his hand and hears successive echoes at regular intervals of 1s. If velocity of sound is 340 m s^(-1) , then the distance between the hills is

A man stands at a distance of 250 m from a wall. He shoots a rifle and hears the echo after 1.3 seconds. Calculate the velocity of sound.
