Question 80

A pulse of sound is emitted from a sonar device on a ship. The sound wave travels down to the seabed, reflects off it, and is detected by the ship's receiver 1.6 s after it was emitted. The seabed is at a depth of 1200 m directly beneath the ship. Using this information, what is the speed of sound in the water?

A

750 m/s750\text{ m/s}750 m/s

B

960 m/s960\text{ m/s}960 m/s

C

1500 m/s1500\text{ m/s}1500 m/s

D
