2.A sailor strikes the side of his ship just below the waterline. He hears the echo of the sound reflected from the ocean floor directly below 3.8s later.

Part A

How deep is the ocean at this point? Assume the speed of sound in seawater is 1560 m/s and does not vary significantly with depth.

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

1.

The speed of a longitudinal waves in a fluid is given by

v = sqrt (B/row) where B is the bulk modulus

A. water = sqrt(2*10^6) = 1414.213 m/s
B. granite = sqrt (45*10^9/2.7*10^3) = 4082.482 m/s
C. steel = sqrt (140*10^9/7800) = 4236.59 m/s

2.

The speed of sound in seawater is 1560 m/s (T=25
