Question

1. A ship sends a sound signal which is reflected from the sea-bed and retu
seconds. What is the depth of sea at the place? The speed of sound in sea-water is 1500
ected from the sea-bed and returns to the ship in 3​

Answer 1

Answer:

given ,

speed = 1500 m/s

t = 3 sec

2S = vt

here ,

S is the distance from the ship to the sea bed

v is the speed of sound

t is the time taken

by substituting the values ,

2S = 1500×3

S = 1500×3 / 2

  = 2250 m

Hence , the depth is 2250 m
