. A force of 0.9 N has a charge of 4.5 x 10-5C is placed near an electric field. Calculate the strength of the electric field.

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.

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
