Assume that the iron block is 175 g and that the beaker contains 75 m hot water, or 75 gince the density of water
is 1.00 if you heat the metal directly on the burner to
about 275°C and then place it in the room temperature (
25° C) water, the temperature of the combined water and
iron equilibrates at 75º C Note that the specific heat of
water is 4.182, J/g•C
Using these values, what is the specific heat of iron in
units of J/g•C? Please answer to the nearest 0.001
J
9 °C

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.
