I think by using data collected by Tycho Brahe
It's called gravity, it attract the sun toward the gravitational pull making everything circulate. I don't really know how to explain it though.
It’s C I hope it helps you
Answer:
g=GM/R^2
Universal Gravutation Constant:
f=GM×m/R^2
Force can be also expressed as
f=m×g
so,
mg=GMxm/R^2
The m gets cancelled so
g=GM/R^2
Explanation:
Below is an attachment containing the solution.
