The mass of Earth is 5.97 Ă— 10^24 kg, the mass of the Moon is 7.35 Ă— 10^22 kg, and the mean distance of the Moon from the center of Earth is 3.84 Ă— 10^5 km. Use these data to calculate the magnitude of the gravitational force exerted by Earth on the Moon.

'According to Lunar Laser Ranging experiment the average distance Lu from the Earth to the Moon is approximately {LL} 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 mass ofthe Earth ME: Give the answer in 1024kg:'

"moon is 7.3476 X 1022 kg_ The The mass of the Earth is 5.972 X 1024 kg and the mass of the 384,400 km. Use the formulas for 'gravity and average distance the moon is from the Earth is 27.5 rotation to solve for the average number of days it takes the moon to orbit the Earth: (Ans: days)"
