50points! find the period of revolution for the planet mercury, whose average distance from the sun is 5.79e10. mass of sun is 1.99e30kg, mass of mercury is 3.3e23kg
Answers: 3
of a body (planet Mercury in this case) orbiting a greater body in space (the Sun) with the size 
of its orbit.
(1)
is the Gravitational Constant and its value is 
is the mass of the Sun
![r=5.79×10^{10}m is the distance from Mercury to the Sun (assuming it is a circular orbit, the semimajor axis is equal to the radius of the orbit). If we want to find the period, we have to express equation (1) as written below and substitute all the values: [tex]T=\sqrt{\frac{4\pi^{2}}{GM}r^{3}}](/tpl/images/0436/6639/cd218.png)
