To keep yourself warm in the winter, you heat a solid metal ball and place it on a stand in the center of your room. The ball has a radius of 16.0 cm and an emissivity of 0.790. If your room has a temperature of 15°C, what is the net power radiated by the ball initially, when the ball's temperature is 200°C?
