Question

A sound wave is used to mesure the distance from the ship to the sea bed. An electronic device

Answer 1

Answer:

Distance, d = 90 meters

Explanation:

Given that,

The speed of sound wave in water, v = 1500 m/s

The  time-base setting for the x-axis is 60 ms per division, $t=60\ ms=60\times 10^{-3}\ s$

Let d is the distance from the ship to the sea bed.​ We know that the product of speed and time is called distance covered.

$d=v\times t$

$d=1500\ m/s\times 60\times 10^{-3}\ s$  

d = 90 meters

So, the distance from the ship to the sea bed is 90 meters. Hence, this is the required solution.
