Assuming the Sun radiates as a blackbody at a temperature of 5800 K, calculate the expected surface temperature of the Earth, assuming that the Earth also acts as a perfect blackbody. Assume the Earth absorbs an amount of energy proportional to its cross-sectional area, but radiates as a spherical blackbody. If the Earth is in thermal equilibrium with outer space, then the energy received (mostly at visible wavelengths) must equal the amount of energy re- radiated (mostly) in the infrared....

An aluminum transmission line with a diameter of 20 mm has an electrical resistance of R'elec= 2.636 × 10-4 Ω/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature. (a) Calculate the conductor temperature...
