If the radius of a star is r and it acts as a black body, what would be the temperature of the star, in which the rate of energy production is Q ? (σ stands for Stefan’s constant.) |
\((4 \pi^2 Q/\sigma)^{1/4}\) \((Q/\sigma 4 \pi^2 )^{1/4}\) \(Q/\sigma 4 \pi^2 \) \((Q/\sigma 4 \pi^2 )^{-1/2}\) |
\((Q/\sigma 4 \pi^2 )^{1/4}\) |
\(\frac{Q}{A} = \sigma T^4 \) ⇒ \( T = [\frac{Q}{4 \sigma \pi R^2}]^{1/4}\) |
