A primitive space heater consists of an iron ball (radius 10.0 cm) through which electrical current is passed in order to heat the ball (and subsequently the surrounding air). If the temperature of the iron ball is kept at 530 K and the room temperature is 20°C, what net power is radiated into the room? Assume the ball is a perfect blackbody.
