When earthquakes produce vibrations called waves, how do those waves travel? they ripple from the epicenter of the earthquake. they move back and forth and side to side through water. they travel away from the focus of the earthquake in all directions. they move slowly and increase in intensity as they reach earth's surface.

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.
