What causes an electric current in a wire? . a)electric fields cause atoms to move in the wire.. b)electrons flow because of electrical attraction and repulsion.. c)electrons move because of heat.. d)electrons build up in the wire and create a charge.

How is zig zagging a form of acceleration?

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.
