Question

32. Suppose a sonar apparatus is attached to the ship and sends ultrasonic waves in the sea.
When the waves reach the bottom of the sea, they are reflected back. If the ultrasonic waves
take 6 seconds to travel from the ship to the bottom of the sea and back to the ship, then what
will be the depth of the sea? [Speed of sound in water = 1500 ms-).​

Answer 1

Answer:

4500m

Explanation:

v=1500m/s

t=6s

We can find the depth by the following formula -> d=vt/2

->d= 1500×6/2

->d=1500×3

->d=4500m
