As additional resistors are connected in series to a constant voltage source, how is the power supplied by the source affected?

(a) the power supplied by the sources remains constant.
(b) the power supplied by the source increases.
(c) the effect on the power supplied by the source cannot be determined without knowing the voltage of the source.
(d) the power supplied by the source decreases.

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.
