Stainless steel ball bearings having a diameter of 1.5 inches are to be quenched in water at a rate of 750 per minute. the balls leave the oven at a uniform temperature of 950°c and are exposed to air at 25°c for a while before they are dropped into the water. if the temperature of the balls drops to 875°c prior to quenching, determine the rate of heat transfer from the balls to the air?

Space vehicles traveling through earth's radiation belts can intercept a significant number of electrons. the resulting charge buildup can damage electronic components and disrupt operations. suppose a spherical metallic satellite 1.3 m in diameter accumulates 3.0 µc of charge in one orbital revolution. (a) find the resulting surface charge density. (b) calculate the magnitude of the electric field just outside the surface of the satellite, due to the surface charge.
