Heat Transfer: Consider a radiator which is connected to electronics generating heat on a satellite so that the radiator can only be cooled by radiative cooling since there's no air.

If the radiator is connected by an aluminum heat pipe which is $10c{m}^2$ in area and $15$ cm long how much thermal power will be dissipated if the electronics are running $50C$ hotter than the radiator

If the radiator must dissipate the amount of power you found in part $($ a $)$ and it has an emissivity of $0\mathrm{.}4$ what surface are must it have if its absolute temperature is $T=293K?$

There is another problem though which is the radiator only dissipates heat when it being shaded by the earth, when its in the sun it will absorb heat. This can be minimized by facing it parallel rather than perpendicular to the suns rays but it will still have an effective surface area of $0\mathrm{.}1m^2$ How much heat does it absorb in the $45$ minutes it is passing through the sunny side of its orbit $($the intensity of sunlight is $1370\frac{W}{m^2})?($this is why the emissivity is so low$)$
