A person of surface area 1.80 m2 is lying out in the sunlight to get a tan. If the intensity of the incident sunlight is 7.00 × 102 W/m2, at what rate must heat be lost by the person in order to maintain a constant body temperature? (Assume the effective area of skin exposed to the Sun is 42% of the total surface area, 57% of the incident radiation is absorbed, and that internal metabolic processes contribute another 90 W for an inactive person.)
