Question:
A large steel ship is partially submerged and motionless in a still sea ("floating"). The steel has a very high density, but the air displaced by the boat has very low density. Together, the average density of the steel plus the air is less than that of the seawater. a. (2 pts). What forces are acting on the ship, and what is the net force? Explain.
b. (3 pts). If the ship were to move upward a few centimeters, regardless of how or why it does so, what would happen to the average density of the fluid the ship displaces? Explain your answer. increase decrease stay same c. (3 pts). If the ship were to move up a few centimeters, what would happen to the buoyant force on the ship? Explain your answer. increase decrease stay same
d. (3 pts). If the ship were to move up a few centimeters, what would happen to the net force on the ship? Explain your answer. point up point down stay same
e. (3 pts). Explain why the floating ship is in a stable equilibrium with respect to up and down motion. To see this clearly, extend the answer to part D to the situation where the ship moves down a few centimeters. f. (3 pts). Why does the ship settle deeper into the water when another passenger climbs aboard? g. (3 pts). The ship's captain can estimate how much cargo the ship is carrying by how deep the ship rides in the water. How does this technique work?
