Answer:

flux star is 5220 times the flux of sun

Explanation:

we know that Stefan–Boltzmann law that total energy radiated per unit surface area of a black body across all wavelengths per unit time ( j) directly proportional to the fourth power of the black body thermodynamic temperature ( T)

so j is sflux and [tex] \sigma [/tex] is constant

[tex]j = \sigma T^{4}[/tex]

here we assume e stars to be black body

so

[tex]\frac{Flux star}{Flux sun} = \frac{\sigma T^{4}star}{\sigma T^{4}sun}[/tex]

[tex]\frac{Flux star}{Flux sun}[/tex] = [tex]8.50^{4}[/tex]

Flux star = 5220 Flux sun

so flux star is 5220 times the flux of sun
