Because it can pollute the air and cause wild life to eat stuff that has been contimanted by the air
Answer:
T=5797.8 K
Explanation:
Given that
Power P = 3.9 x 10²⁶ W
Radius ,r= 6.96 x 10⁸ m
We know that ,From Plank's law
P = σ A T⁴
σ = 5.67 x 10 ⁻⁸
A= Area ,T= Temperature ( in Kelvin)
Now by putting the values
T=5797.8 K
The temperature of surface will be 5797.8 K
