Explanation:
Get on mathpapa is shows you the answer and how to explain it
Explanation:
It is known that formula for area of a sphere is as follows.
A = 
= 
= 3.14 
= (27 + 273.15) K = 300.15 K
T = (77 + 273.15) K = 350.15 K
Formula to calculate the net charge is as follows.
Q = 
where, e = emissivity = 0.85
s = stefan-boltzmann constant = 
A = surface area
Hence, putting the given values into the above formula as follows.
Q = 
= 
= 1046.63 W
Therefore, we can conclude that the net flow of energy transferred to the environment in 1 second is 1046.63 W.
