A solid sphere with radius 3.50 cm is suspended within a large, evacuated enclosure whose walls are at 300.0 K. A power input of 4500.0 W is required to maintain the sphere at 3000.0 K. If heat conduction along the supports is ignored, what is the emissivity of the sphere? (no units) Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10
