An electron of mass 9.1e-31 kg is released from rest at a distance of 8.1 e-10 m from a fixed electron. the force on the movable electron is given by the function f = 2.3e-28/r^2, where r is the distance between the electrons. find the maximum velocity (in meters/second) of the moving electron after release.

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
