Problem suppose you intercept 50 x 10-3 of the energy, Ask an Expert

Academics

Problem: Suppose you intercept 5.0 x 10^-3 of the energy radiated by a hot sphere that has a radius of 0.019 m, an emissivity of 0.81, and a surface temperature of 570 K.

A- How much energy do you intercept in 3.2 min?

Show how you get the answer, so that I can better understand how to do it. Thank you.
