How is a body considered a blackbody? a. If and only if ɛ = a = 1.0 b. If it absorbs incident rays and transmits none. If the emissive power is calculated using the Stefan-Boltzmann Law. d. More than one response. e. None of these. С. е. If one uses Reciprocity Law, which of the following is true? a. There are only two areas being considered, separated by a certain distance. b. More than two areas can be considered, as long as only two surfaces with different temperatures are considered in calculations. If object 1 is flat, then A F12 = A2F12 = A¡F11. d. If A1 =A2, then F12 = F22. С. е. More than one response. f. None of these. In creating a network circuit for M = 3 enclosures, this all holds true except: An SSR requirement must be met, that is one should be a refractory material. b. Re-radiating bodies are considered free floating, that is, their conductance becomes infinite. c. Application of Kirchhoff's Law at the node shall only be done in between radiosities and sink/source. d. A negative value of q obtained from SSR Method means that the flow of electricity assumed is incorrect. e. If a material is insulated, the resistance between this material and the sink/source becomes zero. %3D а. How is a body considered a blackbody? a. If and only if ɛ = a = 1.0 b.
