Compute the each part of following question given below:

Question: Assume the intensity of solar radiation incident on the upper atmosphere of the Earth is 1,315 W/m² and use data from the Useful Planetary Data table as necessary.

Part I: Determine the intensity of solar radiation incident on Neptune.

W/m²

Part II: Determine the total power incident on Neptune.

W

Part III: Determine the radiation force that acts on that planet if it absorbs nearly all the light.

N

Part IV: State how this force compares with the gravitational attraction exerted by the Sun on Neptune.

(Gravitational force exerted on Neptune by the Sun)/(light-pressure force on Neptune) =

Part V: Compare the ratio of the gravitational force to the light-pressure force exerted on the Earth with the ratio of these forces exerted on Neptune, found in part (d).

(Gravitational force exerted on Earth by the Sun)/(light-pressure force on Earth) =

I need help to solve the above question and please keep answer short and simple and please no copy and paste.
