If the temperature of an object is multiplied by 7 , the amount of power radiated is multiplied by what number?

2401

Explanation:

The amount of power radiated  by an object can be calculated with the Stefan-Boltzmann law, this law is expressed as:

In this problem, it's supposed that we move from state 1

()

where all the variables are known, to state 2, where , , , and T is 7 times bigger than before, so to find we have the replace .

This means that the amount of power radiated is multiplied by 2401.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
