A person claps his hands near a cliff and hears the eco after 2 seconds if the speed of the sound in air is 340m/s find the distance of the cliff from the percent
To have the sound travel back and forth, it must be 2*340m.
2.3
To find the distance of the cliff from the person, we can use the formula:
distance = speed × time
In this case, the speed of sound in air is given as 340 m/s and the time taken for the echo to reach the person is 2 seconds.
Therefore, the distance of the cliff from the person can be calculated as:
distance = 340 m/s × 2 seconds = 680 meters
So, the cliff is located approximately 680 meters from the person.
