In a television picture tube, electrons strike the screen after being accelerated from rest through a potential difference of 27000 v. the speeds of the electrons are quite large, and for accurate calculations of the speeds, the effects of special relativity must be taken into account. ignoring such effects, find the electron speed just before the electron strikes the screen.

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.
