Determine the expression for E in terms of S, σ, T, and S0.

1. E = SσT^4/S0
2. E = SσT^3/S0
3. E = SσT^2/S0
4. E = SσT/S0

Correct answer: E = SσT^4/S0

Solution

The given equation matches option A, where E is proportional to SσT^4/S0. This is consistent with the Stefan-Boltzmann law and energy flux relationships.
