Two parallel disks which are separated by a distance of 25 cm are enclosed in a large evacuated chamber that is at -250 c temperature. the larger disk is 50 cm in diameter, is at 800 c, and has an emissivity of 0.6. the smaller disk is 25 cm in diameter, is at 400 c temperature, and has an emissivity of 0.4. calculate the radiative power lost by the large disk. hint: note that the disks lose heat from both sides.
