Question

Question 8 2 pts Using the Stefan Boltzman law, what is the energy emitted by the sun in Watts Per Meter Squared (Wm 2), assuming the sun has a temperature of 6000 K?

Answer 1

Answer:

73,483,200 W/m^2

Explanation:

BY the stefan Boltzman law the energy radiated by a body is propotional to fourth power of its absolute temperature. Sun is considered to be black body,hence ts emisivity is one.

E= σT^4

σ= Boltsman constant = 5.67×10^(-8)

putting values we get

$E= 5.67\times10^{-8}\times6000^4$

= 73,483,200 W/m^2

energy emitted by the sun = 73,483,200 W/m^2
