A ship spends a sound wave to the bottom of the sea and receives it back in 3 seconds . calculate the depth of the sea
Answers
Explanation:
let depth be x 1480 speed sound
2x time is 3 then 2x/1480=3
2220m
Answer:
depth of sea = 2250 m
Explanation:
Given: ship spends a sound wave to the bottom of the sea and receives it back in 3 seconds.
Find: calculate the depth of the sea.
Solution:
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=3s
sSo, 2x=vt
sSo, 2x=vtOr 2x=1500×3
⟹ x=750 × 3m
x= 2250m
