A) The emissivity of the human skin is 97.0 percent. Use 35.0 °Cfor the skin temperature and approximate the human body by arectangular block with a height of 1.84 m, a width of 30.0 cm and alength of 24.0 cm. Calculate the power emitted by the humanbody.
B) Fortunately our environment radiates too. The human bodyabsorbs this radiation with an absorbance of 97.0 percent, so wedon't lose our internal energy so quickly. How much power do weabsorb when we are in a room where the temperature is 23.5 °C?
C) How much energy does our body lose in one second?
