What is the total charge of the radon nucleus? (the neutral radon atom has 86 electrons.) tries 0/20 what is the magnitude of its electric field at a distance of 1.96×10-10 m from the nucleus? tries 0/20 what is the magnitude of the force on an electron at that distance? tries 0/20 what would the magnitude of the force be if the distance of the electron from the nucleus were halved?

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.
