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 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 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 a vertical wall at a certain distance beats a drum at regular intervals. The drumming rate is gradually increased and he find that the echo is not heard distinctly when the drumming rate becomes 2 beats in 3 seconds. He then moves nearer to the wall by 90m and finds the echo is again not heard when the drumming rate becomes 1 per second. From this data, the velocity of sound must be

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 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.

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 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

Suppose a man stands at a distance from a cliff and claps his hands . He receives an echo from the cliff after 4 second . Calculate the distance between the man and the cliff . Assume the speed of sound to be 343 m s^(-1)
