The average power of the sun is 3.79x1026 watts, answer the following questions: 13. what is the average intensity of light at earth's position? 14. what would be the pressure on a solar sail due to the light of the sun if it's (a) fully reflective or (b) fully absorptive?

Explanation:

Given that,

Average power of sun

We need to calculate the intensity of light at Earth's position

Using formula of intensity

Where, I = intensity

P = power

Put the value into the formula

So, The intensity is 1347.616 W/m².

(A). We need to calculate the pressure on a solar sail due to the light of the sun if it's fully reflective

Using formula for fully reflective

Put the value into the formula

(B).  We need to calculate the pressure on a solar sail due to the light of the sun if it's fully reflective

Using formula for fully absorptive

Hence, This is the required solution.
