Example 2.9b is confused the heck out of me.... I can't figure out why Answer A is the correct answer
When Johannes Kepler, 17th-centry astronomer and smart guy, predicted a relationship between the mean orbital radius and orbital period of a planet about the Sun, he found that the period squared is:
A) proportional to the cube of the orbital radius
B) proportional to the square of the orbital radius
C) proportional to the orbital radius
D) proportional to the square root of the orbital radius
