Question

Quizplus · Accepted Answer

Neptune is much farther from the Sun than Jupiter, so it receives less energy per square meter. The amount of energy received from the Sun varies with the inverse square law of distance. Neptune is about 30 times farther from the Sun than Jupiter, so it receives about 1/30^2 (or 1/900) as much energy per square meter as Jupiter. Simplifying, we get that Neptune receives about 1/36 as much energy per square meter as Jupiter. Therefore, the correct choice is A) about 1/36 as much.
