In order for a full-wave bridge rectifier to convert AC to DC, there must be A); diodes going the same direction connected to both sides of the diode B); diodes going in opposite directions connected to both sides of the diode C); a diode directed into the positive side of a resistor and into the negative side of the resistor D); a diode directed out the positive side of a resistor and out the negative side of the resistor

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.
