Question

a sonar apparatus in a ship sends out a signal vertically downwards . the signal returns after 1.6s . find the depth of the sea . the velocity of the sound in water = 1500 m/s .
PLEASE EXPLAIN THE QUESTION AND TELL FAST. YOU WILL BE MARKED BRAINLIEST.​

Answer 1

Answer:

Velocity of sound in water v=1500 m/s

Velocity of sound in water v=1500 m/sLet the depth of sea be x.

Velocity of sound in water v=1500 m/sLet the depth of sea be x.The sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.

Velocity of sound in water v=1500 m/sLet the depth of sea be x.The sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.Time taken to hear an echo t=1 s

Velocity of sound in water v=1500 m/sLet the depth of sea be x.The sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.Time taken to hear an echo t=1 sSo, 2x=vt

Velocity of sound in water v=1500 m/sLet the depth of sea be x.The sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.Time taken to hear an echo t=1 sSo, 2x=vtOr 2x=1500×1

Velocity of sound in water v=1500 m/sLet the depth of sea be x.The sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.Time taken to hear an echo t=1 sSo, 2x=vtOr 2x=1500×1⟹ x=750 m
