Question

Sonic vibrations were sent down from a ship return after 2 seconds. What is the depth of the sea, if the speed of sound in water is 1.5 1 km s− ?​

Answer 1

Answer:

1.51 km

Explanation:

let , the depth of the sea = d km, then

Total distance covered by sound to travel and return = 2d km

Now,

distance = speed x time

2d = 1.51km/s x 2 s

2d = 3.02km

d = 1.51 km.
