A man stands before a large wall at a distance of 50.0m 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.

AI Generated Solution

To find the velocity of sound in air based on the given scenario, we can follow these steps: ### Step 1: Understand the scenario The man is standing 50 meters away from a wall and claps his hands. When he claps, the sound travels to the wall and then reflects back to him. The total distance traveled by the sound is the distance to the wall and back. ### Step 2: Calculate the total distance traveled by sound The distance to the wall is 50 meters, and the sound has to travel back as well. Therefore, the total distance traveled by the sound 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 standing in front of a mountain beats a drum at regular intervals. The drumming rate is gradually increased and he finds that echo is not heard distinctly when the rate becomes 40 per minute. He then moves near to the mountain by 90 metres and finds that echo is again not heard distinctly when the drumming rate becomes 60 per minute. Calculate (a) the distance between the mountain and the initial position of the man and (b) the velocity of sound.

A boy standing in front of a wall at a distance of 85 m produces 2 claps per second. He notices that the sound of his clapping coincides with the echo. The echo is heard only once when clapping is stopped. Calculate the speed of sound.

A boy stands 60 m in front of a tall wall and claps. The boy continues to clap every time an echo is heard. Another boy finds that the time taken between the first and fifty-first clap is 18 s. Calculate the speed of sound.

A man is standing on top of a building 100 m high. He throws two balls vertically, one at t = 0 and other after a time interval (less than 2s). The later ball is thrown at a velocity of half the first. The vertical gap between first and second ball is 15 m at t = 2. The gap is found to remain constant. The velocities with which the balls were thrown are (Take g = 10 m s^(-1) )

A boy throws balls into air at regular interval of 2 second. The next ball is thrown when the velocity of first ball is zero. How high do the ball rise above his hand? [Take g=9.8m//s^(2) ]

A man is standing on top of a building 100 m high. He throws two ball vertically, one at t=0 and after a time interval (less than 2 seconds). The later ball is thrown at a velocity of half the first. At t=2 , both the balls reach to their maximum heights at this time the vertical gap between first and second ball is +15m . Q. The speed of first ball is
