Question

17 1. Which statement about Kepler's law of harmonies is correct?

A. There is a direct relationship between the orbital period and the radius of orbit.
B. There is an indirect relationship between the orbital period and the radius of orbit.
C. The smaller a planet's orbital period, the greater is its radius of orbit.
D. The smaller a planet's radius of orbit, the greater is its orbital period​

Answer 1

B

Step-by-step explanation:

Let T be the orbit period and a be the radius of orbit.

For T^2= k× a^3 (k is a constant)

there seems to be an indirect relationship between two variables.
