Multiple Choice
Planet 1 and planet 2 are both in circular orbits around the same central star.The orbit of planet 2 has a radius that is much larger than the radius of the orbit of planet 1.This means that:
A) the period of planet 1 is greater than the period of planet 2 and the speed of planet 1 is greater than the speed of planet 2
B) the period of planet 1 is greater than the period of planet 2 and the speed of planet 1 is less than the speed of planet 2
C) the period of planet 1 is less than the period of planet 2 and the speed of planet 1 is less than the speed of planet 2
D) the period of planet 1 is less than the period of planet 2 and the speed of planet 1 is greater than the speed of planet 2
E) the planets have the same speed and the same period
