Application: Assume a small spacecraft is in open space. One panel is a dedicated radiator $($dimensions in image$)$ and is painted with S$13$ GLO white paint $($emissivity $=\mathrm{.}89).$ If the radiator is at $30C$ and has a full view factor to space, how much heat can it reject from the system? $($How much is this radiator radiating to space?$).$ Use $3K$ for space temperature. Round answer up to one decimal place. No need to include units. $($Remember that $\frac{-}{+}$ signs are used in respect to direction of energy transfer$)$
