Question
Chapter 4, Problem 49Q
To determine
The student who reaches the right conclusion. According to the first student, lower orbits have higher energies because Kepler’s second law states that the closer planets have a higher speed, whereas according to the second student, the orbits at larger distances must have higher energies because rockets have to expend more energy to launch satellites farther into space.

Which scientist is credited with the collection of data necessary to support the planet's elliptical motion?
What is the gravitational acceleration from the center of a spherical object whose mass is 3.9*10^23 kg at a distance of 6.7*10^6 m?
Round your answer to the nearest hundredth and use scientific notation
Newtons version of Kepler's third law is P2=4pi2/(G(M1+M2)) x a3. Since the square of the period P varies inversely with the Sum of the masses (M1+M2), the period itself depends on the inverse square root of the object masses. If a solar system has a star that is 3.9 times as massive as our Sun, and if that solar system has Earths exact twin, what is the orbital period of that planets months ?
