A stone is dropped from rest into a well. The sound of the splash is heard exactly 2.00 s later. Find the depth of the well if the air temperature is 10.0°C.
Given Info: Temperature of the air is
Formula for speed of sound in air is,
Substitute
Formula to calculate the depth of the well,
- h is the depth of the well
- g is the acceleration due to gravity
- t is the time for the stone to fall in to the well.
