Two concentric spheres have diameters of 6 cm and 10 cm. The inner one is at a temperatureof 1000 K and the other one at 300 K. Calculate the heat lost by radiation by the inner spherefor the following cases:(a) The surfaces of both spheres are black.(b) The surface of the outer sphere is diffuse and has an emissivity of 0.3. The inner sphere is black.(c) A spherical shield of diameter 8.0 cm and diffuse surface of emissivity 0.5 (on both sides) isplaced between the two spheres of (b).(d) All the surfaces in (c) are specular, with a total emissivity of 0.5.
