Star A has a radius 10 times the Sun's radius. If its temperature is the same as the Sun's, then the luminosity of Star A is_____times larger than that of the Sun.What is the luminosity of a star if it has a radius 10 times the sun's and the same temperature as the sun?L = R^2(T/Tsun)^4
Tsun = 5,780 Kelvin = Tstar
L = 10^2(5,780/5,780)^4
L = 100 times more luminous than the sunWhat is the luminosity of a star if it has a radius 10 times the sun's and the same temperature as the sun?Use the equation:
L_A/L_Sun = (R_A/R_Sun)^2 (T_A/T_Sun)^4
This give: L_A = (10^2) (1)^4 (L_Sun)
L_A = 100 L_Sun
