Life cycle
The life cycle of the star is the transitions it undergoes from the time it start to function until the the time it stops functioning.
Answer:
The electromagnetic radiation per-unit- area increase by 42.65 times.
Explanation:
The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,
P ∝ T⁴
For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:
![\frac {P_1}{P_0}=\frac {T_1^4}{T_0^4}](https://tex.z-dn.net/?f=%5Cfrac%20%7BP_1%7D%7BP_0%7D%3D%5Cfrac%20%7BT_1%5E4%7D%7BT_0%5E4%7D)
T₀ = 900 K
T₁ = 2300 K
![\frac {P_1}{P_0}=\frac {2300^4}{900^4}](https://tex.z-dn.net/?f=%5Cfrac%20%7BP_1%7D%7BP_0%7D%3D%5Cfrac%20%7B2300%5E4%7D%7B900%5E4%7D)
So,
<u>P₁ = 42.65 P₀</u>
<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>
