Question

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

placed in the ship traces a pulse sent from the ship and reflected pulse that returns. The
Time-base setting for the x-axis is 60 ms per division.
The speed of sound wave in water is 1500 m/s. Find
the distance from the ship to the sea bed.​

Answer 1

Distance, d = 90 meters

Step-by-step 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* 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* t`

`d=1500\ m/s* 60* 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.
