(a)Calculate the rate in watts at which heat transfer through radiation occurs (almost entirely in the infrared) to 4.0 m2 of the Earth's surface at night. Assume the emissivity is 0.95, the temperature of the Earth is 15°C, and that of outer space is 2.7 K. (Include the sign of the heat transfer to 4.0 m2 of the Earth's surface in the value of your answer.) (b)Compare the intensity of this radiation with that absorbed by the Earth from the Sun during the day. The intensity of the radiation from the Sun averages about 800 W/m2, only half of which is absorbed by the Earth. (c)What is the maximum magnetic field strength (in µT) in the outgoing radiation, assuming it is a continuous wave?
Suppose you stand with one foot on ceramic (k=33 W/mK) flooring and one foot on a wool carpet (k =0.033 W/mK), making contact over an area of 65cm2 with each foot.
