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.

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.

A splash in heard 3.12 s after a stone is dropped into a well 45 m deep. The speed of sound in air is [ g =10 ms ^(-2)]

A stone is dropped into a well 44.1 deep. The sound of splash is heard 0 . 13 seconds after the stone hits the water. What should be the velocity of sounds in air .

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 45 m deep. The sound of the splash of the splash is heard 3.13 s after the stone is dropped. Find the speed of sound in air. Take g = 10 m//s^2 .

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 .

An iron block is dropped into a deep well. Sound of splash is heard after 4.23 s. If the depth of the well is 78. 4 m , then find the speed of sound in air (g=9.8 m//s^(2))

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 man stands between two parallel cliffs (not in middle). When he claps his hands, he hears two echoes one after 1 second and the other after 2 second. If the velocity of sound in air is 330 ms^(-1) , the width of the valley is
