Physics

Part A.The emissivity of the human skin is 97.0 percent. Use35.0 °C for the skin temperature and approximate the human body bya rectangular block with a height of 1.56 m, a width of 38.5 cm anda length of 33.5 cm. Calculate the power emitted by the human body.  

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?
