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

Idk about the harmonic law, but mercury is the closest to the sun and neptune is the farthest/ furthest. mercury has the smallest orbit and neptune has the largest. so neptune would take a longer amount of time to orbit the sun.

Cis the on
