Three identical garden hoses (same length and same inner diameter) are attached to three identical faucets which supply water at the same pressure to all three hoses. All three hoses are open to the atmosphere at their other ends. Hose A runs along a level path at the elevation of the faucet. Hose B runs down a hill and its free end is 10 ft below the level of the faucet. Hose C runs up and over a high wall, but its free end is back at the elevation of the faucet. Required:
How do the flow rates through the three hoses compare? Justify your answer. Make certain to explicitly show the pair of points you are applying the model between; this should be your first step in solving these problems. Please use the Bernoulli equation to solve:

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
