Which example best illustrates the transfer of energy between two waves?

a)a buoy rises in the water as a boat speeds past. b)a basketball rebounds from the backboard during a missed shot. c)an egg that rolls off the counter falls and breaks on the floor. d)a car that rear ends another car causes damage to both vehicles.

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.
