The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human body by a rectangular block with a height of 1.76 m, a width of 43.5 cm and a length of 22.0 cm. Calculate the power emitted by the human body. 2301 J units. No What is the wavelength of the peak in the spectral distribution for this temperature? Fortunately our environment radiates too. The human body absorbs this radiation with an absorbance of 97.0 percent, so we don't lose our internal energy so quickly. How much power do we absorb when we are in a room where the temperature is 23.0 °C? How much energy does our body lose in one second?

Part A A large cavity that has a very small hole and is maintained at a temperature T' is a good approximation to an ideal radiator or blackbody. Radiation can pass into or out of the cavity only through the hole. The cavity is a perfect absorber, since any radiation incident on the hole becomes trapped inside the cavity. Such a cavity at 500° has a hole with area 5.00 mm². How long does it take for the cavity to radiate 200 J of energy through the hole? Express your answer in seconds.
