Asolar sail is made of aluminized mylar having an emissivity of 0.03 and reflecting 95% of the light that falls on it. suppose a sail with area 1.35 km2 is oriented so that sunlight falls perpendicular to its surface with an intensity of 1.40 103 w/m2. to what temperature will it warm before it emits as much energy (from both sides) by radiation as it absorbs on the sunny side?
