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 2.0 s later.

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.

Solutions

Expert Solution

let the depth of the ocean be h
total distance travel by sound S = 2h
time of echo t = 2 s
speed of sound in sea water v = 1560 m / s
we know v = S / t = 2h / t
from this h = vt / 2
= 1560 m

A sailor strikes the side of his ship just below the surface of the sea. He hears the echo of the wave reflected from the ocean floor directly below 10.0 s later. How deep is the ocean at this point? (Note: Use the bulk modulus method to determine the speed of sound in this fluid, rather than using a tabluated value.)_____ m

Jim is lifting weights. Holding a 20lb weight down by his side, he bends his arm at the elbow, contracting his bicep, and holds the position until he reaches muscle fatigue. Briefly describe how the Henneman Size Principle relates to this example. List the steps of muscle fiber recruitment necessary for the initial lift and subsequent fatigue. Include a short summary of the muscle fiber types, and the properties that contribute to the speed of contraction, recruitment pattern and metabolic...

Mr. Smith is contemplating retirement. He has just celebrated his 50 birthday and his net worth is $2.5 million. He hopes that after retirement he can maintain a lifestyle that costs him $110000 per year in today's dollars (i.e., real dollars, inflation adjusted). For simplicity, assume that all expenses occur at the end of each year; the first expense of $110000 will happen one year from now. If he retires, he will invest all his net worth in government bonds...

James has just jumped out of an airplane. After he opens his parachute he experiences 2 forces: the constant force of gravity, and a wind drag that is proportional to his velocity. His height may therefore follow the equation: d2h/dt2 = -9.8 - 2(dh/dt). As a second-order differential equation, this is not technically solvable by separation of variables. However, because the variable h appears only in its derivatives, we can turn this into a first-order equation, and solve that by...
