A blacksmith is flattening a steel plate having dimensions 25.7 cm x 27.7 cm. The plate is heated to some temperature, the radiation from the plate is measured to be 816 Watts. If the emissivity of the plate is 2.00, what is the temperature of the plate? Ignore any heat exchange with the surroundings and don't worry about the thickness of the plate. (o = 5.67 x 10-8 W/m2.K4) Your answer should only have digits before the decimal.

A square plate of edge length 14.0 cm and negligible thickness has a total charge of 5.20 times 10^-6 C. Estimate the magnitude E of the electric field just off the center of the plate (at say, a distance of 0.50 mm from the center) by assuming that the charge is spread uniformly over the two forces of the plate. Estimate E at a distance of 35 m (large relative to the plate size) by assuming that...
