What is the ratio of the mass of the Earth to that of the Moon? 4 43 70 110 none

A space agency sent a satellite to a nearby planet to take photographs over a period of several years. The satellite orbits the planet once every 6 hours and 10 minutes. If the satellite is orbiting at a radius of 9.44∗107 m, what is the mass of the planet?   A) 8.22∗10^29 B) 4.34∗10^26 C) 1.01∗10^27 D) 7.04∗10^26

If the earth has a period of 9.94x1014 seconds and the mass of the sun is 1.989 x1030 kg, find the distance between these two bodies.

Given the orbital radius and period of a moon, derive an algebraic solution for the mass of the planet that moon orbits. Watch those units, convert to SI.

The moon's period of revolution around the Earth is 27.3 d. How far away is the moon from the surface of the Earth? O A) 1.33× 107 m B) 3.83 × 108 m C) 3.77 × 108 m D) 4.88 × 10⁹ m

Two spherical objects have masses of 215kg and 596kg. Their centers are separated by a distance of 29m. Find the gravitational attraction (force) between them.  Round your answer to the nearest hundredth and use scientific notation.

B) what is the period of the orbit, in hours?

None

According to Lunar Laser Ranging experiment the average distance LM from the Earth to the Moon is approximately 3.92 x 105 km. The Moon orbits the Earth and completes one revolution relative to the stars in approximately 27.5 days (a sidereal month). Calculate the orbital velocity of the Moon in m/s. Answer: Choose...
