An inductor in the form of an air-core solenoid contains 191 turns, is of length 17.9 cm, and has a cross-sectional area of 1.2 cm^2 . the permeability of free space is 1.25664 × 10^−6 n/a^2 . what is the magnitude of the uniform rate of change in current through the inductor that induces an emf of 205 µv? answer in units of a/s.

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.
