The splash of a stone in a wall is heard `tau=2.053 s` after the stone is let fall. Calculate the depth of the well assuming the velocity of sound in the well `v=400 m//s`.

If the splash is hear 4.23 seconds after a stone is dropped into a well, 78.4 metres deep, find the velocity of sound in air.

The echo of a gunshot is heard 5 seconds after it is fired. Calculate the distance of the surface which reflects the sound. The velocity of sound is 332m/s.

12.A body is dropped into a deep well.Sound of splash is heard after 4.23s .If the depth of the well is 78.4mthe velocity of sound in air is

A stone is dropped into a well. The splash is heard 3.35 s later. What is the depth of the well?

The splash of sound was heard 5.35 s after dropping a stone into a well 122.5 m deep. Velocity of sound in air is

A stone is dropped into a well and the sound of inpact of stone on the water is heard after 2.056 sec of the release of stone form the top. If acc. Due to gravity is 980 cm//sec^(2) and velocity of sound in air is 350 m//s , calculate the depth of the well.

The sound of a thunder is heard 6 s after the lightning flash from a cloud at an angle of 60^(@) to the horizontal. Calculate the height of cloud above the ground. The velocity of sound in air is 340 m/s.

A stone is dropped into a well and its splash is heard at the mouth of the well after an interval of 1.45 s.Find the depth of the well. Given that velocity of sound in air at room temperature is equal to 332 ms^(-1) .

A stone is dropped in a well 107 m deep. If the splash is heard 5 seconds after the stone is dropped, then calculate the speed of sound in air.
