(20 pоints) A smаll surfаce оf аrea A1 = 10-3 m2 is knоwn as a blackbody at a uniform temperature of 2727℃. Determine: 1) the total intensity of the radiation that emerges from A1, 2) the rate at which this emission is intercepted by a small surface of area A2 = 5x10-4 m2, which is oriented as shown in the schematic. To receive full credit, include all units in your answers. Stefan-Boltzmann constant is 5.67 x 10-8 [W/(m2·K)].
