At what rate would you lose energy, Physics

Assignment Help:

you were to walk briefly in space without a spacesuit while far from the Sun (as an astronaut does in the movie 2001), you would feel the cold of space --while you radiated energy, you would absorb almost none from your environment. Assume that your emissivity is 0.90, the surface area of the average human body to be about 2 m2, and the skin temperature to be about 300 K.

(a) At what rate would you lose energy?
(b) How much energy would you lose in 55 s?
