** Please answer the question without using Calculus. This is an algebra based Physics course. Thank you! **

a) Over 2 millenniums ago, intellectuals in the ancient world concluded the earth's radius. This determined value is about RE = 6400 km.

More than 70 years after Isaac Newton formulated his law of universal gravity, Cavendish made a direct measurement of the gravitational constant. This value is about G = 6.7 x 10-11 Nm2/kg2.

Show how to calculate the mass of planet earth, ME.

b) Ancient scholars also figured out that the earth orbits the sun in a nearly circular orbit with a radius equal to 23,000RE.

Show how to calculate the mass of the sun, MS.

Please show all steps if possible. Thank you!
