A stone is dropped into a well of depth 196m the splash is heard after 6.88 second find velocity of sound in air
need it immedietly please help
The velocity will be 28.488 and rounded off will be 2.5 meters/second. To calculate velocity, you need to divide the distance by time takes (v =d/t). That means you divide 196 meters by 6.88 seconds, which is 196/6.88 and you get 28.5 m/sec.
