A) Astronomers on planet Zog whose sun is 1.4 x 10^11 m away, measure their solar flux to be 1250 W/m^2. What is their sun's total energy output?

B) The astronomers on Zog find that their sun's spectrum agrees with that of a blackbody of temperture 5500 K. What is the radius of their sun?

C) Astronomers on Earth observe a radiant power of 10.6 x 10^-9 W/m^2 for the star which is the sun for planet Zog. How far away is this from Earth in m?

D) Astronomers would more likely report this distance in parsecs. How far away is it in parsecs?
