Surface of swimming pool and released from rest-beach ball

Reference no: EM13545196

A beach ball filled with air is pushed about 1 m below the surface of a swimming pool and released from rest. Which of the following statements are valid, assuming the size of the ball remains the same? (Select all that apply.)

a) The buoyant force on the ball decreases as the ball approaches the surface of the pool.

b) As the ball rises in the pool, the buoyant force on it increases.

c) The buoyant force on the ball equals its weight and remains constant as the ball rises.

d) The buoyant force on the ball while it is submerged is approximately equal to the weight of the volume of water that could fill the ball.

e) When the ball is released, the buoyant force exceeds the gravitational force, and the ball accelerates upward.
