In order to catch a ball, a baseball player moves his hand backward in the direction of the ball's motion. Doing this reduces the force of impact on the player's hand principally because it:. a. decreases the impulse on the glove.
b. decreases the change in momentum of the ball.
c. increases the impact time
d. increaes the impulse on the gove

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
