Two concentric, hollow spherical shells have radii R1 = 5 cm and R2 = 10 cm. The smaller sphere has a charge of Q distributed uniformly over its surface, while the larger sphere has an opposite charge –Q. Let Q = 7.0 µC. Find the electric field the following distances from the centers of the spheres; give the directions as well, indicating either "away from the center" or "toward the center" (unless the field is zero).a. 2.5 cm from the centersb. 7.5 cm from the centersc. 12.5 cm from the centers

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.
