Question

a sound wave sent out from a boat a mives back after 3 seconds.. if the speed of sound in water is 1500 m/ s , how deep is the water​

Answer 1

Answer:

Answer is 250m

Explanation:

The sound wave travels twice.

From the boat to the sea floor, then from the sea floor to the boat.

Then let us consider D has the distance of the sea floor from the boat.

Since it has to travel twice, the distance covered by the sound wave is 2D

Speed= D*T is the formula for finding speed where T is time taken.

1500m/s is the speed.

Since it took three seconds to arrive back, let the Distance covered be 4500m

2D=4500

D=2250m
