Question

a ships sonar sends messages and receives the echoes the ocean bottom 0.6 seconds after the sound is sent down from the ship.how deep is water beneath the ship?(given speed of sound in still water=1450m/s)

Answer 1

Answer:

Total Time taken = 0.6 seconds

Time taken to reach the bottom = t = 0.6/2 = 0.3 seconds

Speed of sound in water = s = 1450m/s

Using S = D/t                    (Where D = Distance)

D = St

D = 1450*0.3

D = 435m

Therefore, the water 435m deep beneath the ship.

Answer 2

Answer:

its 340 ×0.6 which is equal to 204m.
