Question

The ultrasonic waves take 10 seconds to travel from the ship to the bottom of the sea and
back to the ship. What is the depth of the sea ? (Speed of sound in water = 1600m/s.)
O 1000 m
O 2000 m
0 3000 m
O 8000 m​

Answer 1

Answer:

Let, the Depth of sea is x, 

Distance traveled by sound wave=2d,

 Time is taken by sound to travel both ways=1.6s, 

Speed of the sound =time takentotal distance travelled=1400m/s=1.6s2d

d=1120m
