Suppose your surface body temperature averaged 90 degrees f. how much radiant energy in w/m^2 would be emitted from your body?

.

The Stefan-Boltzmann Law gives the energy radiation per unit area of a black body:

where,

.

.

.

Keep as many significant figures in as possible. The error will be large when is raised to the power of four. Also, the real value will be much smaller than since the emittance of a human body is much smaller than assumed.

50 inches should be the resultant vector

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
