Question

the harmonic law would suggest that neptune will take ______ to orbit the sun than mercury.
○ a shorter amount of time
○ equal amounts of time
○ a longer amount of time

Explanation:

The harmonic law (Kepler's third law) states that the square of the orbital period of a planet is proportional to the cube of its average distance from the Sun. Neptune is much farther from the Sun than Mercury. So, a planet farther from the Sun takes a longer time to orbit. Thus, Neptune takes a longer amount of time to orbit the Sun than Mercury.

Answer:

a longer amount of time
