Answer:
The ocean is 2497.34 meters beneath the ship.
Explanation:
Given that,
The speed of sound in water, v = 1403 m/s
A sonar signal is sent from a ship at a point just below the water surface and 1.78 s later the reflected signal is detected, t = 1.78 s
Let d is distance of the ocean beneath the ship. It is given by :
[tex]d=v\times t\\\\d=1403\times 1.78\\\\d=2497.34\ m[/tex]
So, the ocean is 2497.34 meters beneath the ship.
