1. The problem statement, all variables and given/known data A planet's mean distance from the sun is 2.00x10^11 m. Determine the planet's orbital period. Use information found in textbook. 2. Relevant equations So I use the following equations: R=h+Rs T=2∏√(R3/GxMs) From the textbook I got the following values: Rs=6.96x108m ms=1.99x1030kg 3. The attempt at a solution From the problem we also know that h=2x1011m So with that and the radius of the sun we are able to find the radius that will be used in the orbital period equation. R=(6.96x108m)+(2x1011m)=2.007x1011m with all these values we plug them into the orbital period equation and solve for T=49034131.61 I don't know how to get the units for the period however... If someone could tell me if my calculations are correct and how I find these units that would be greatly appreciated! Thank you so much in advance for your time and help!
