Question

c) In a SONAR, ultrasonic waves are sent in to the sea water and reflected waves from a
sunken ship are received after 2 sec. If the velocity of waves in sea water is 1450 m/s. Find the
depth of the sunken ship.​

Answer 1

Answer:

divide 1450m/s by 2s which equals to 725m is your answer

Explanation:

Answer 2

Question :-

In a SONAR, ultrasonic waves are sent in to the sea water and reflected waves from a sunken ship are received after 2 sec. If the velocity of waves in sea water is 1450 m/s. Find the depth of the sunken ship.

Answer :-

Given :-

• Time taken by the reflected rays to reach back the SONAR = 2s

• Speed (or velocity) of waves = 1450 m/s

To find :-

• Depth of the sunken ship

Solution :-

We know that,

$\boxed{Speed=\frac{Distance}{Time}}$

After substituting the values, we get the formula as,

$\boxed{Distance=Speed\times{Time}}$

Now,

Distance = 1450 × 2

$\Rightarrow$Distance = 2900 meters

or 2.9 km (as 1000 m = 1 km)

______________________________________

$\therefore$ The depth of the ship was 2900 m
