What is the Roche limit (in units of Earth radii) for the real Moon if the Earth were made entirely of iron? Roche limit for Iron-Earth : _______ Earth radii

The author mentions in one place that the Moon is approximately 60 Earth radii away. In another place he says the Moon is about 10 times the Earth's girth away (in this case, girth really means "how far around") Without looking up the numbers for the Earth's size or the real distance to the Moon, show that these two statements are roughly consistent with each other. Describe why this is true. Why are the planets close to the Sun in...
2. Given that the moon has a period of 27.32 days around Earth and a radius of orbit which is 60 Earth radii, what is the centripetal acceleration of the moon?
what is the distance from the moon to the point between earth and moon where the gravitational pulls of earth and moon are equal? mass of earth is 5.97x10^24 kg, mass of moon is 7.35x10^22 kg, distance between earth and moon is 3.84x10^8 m, and G=6.67x10^-11 Nm^2/kg^2.How do I do this problem?
please help! answer is shown below but I need help with the process. so please show all work and I will rate!! 5. Suppose that the attraction between the Moon and the Earth were due to Coulomb forces rather than the gravita- tional force. a) What would be the magnitude of the charge required if equal but opposite charges resided on both the Earth and the Moon, and the electrostatic attraction equalled the gravitational one? b) If the Earth were...
There is a moon orbiting an Earth-like planet. The mass of the moon is 5.37 × 1022 kg, the center-to-center separation of the planet and the moon is 5.34 × 105 km, the orbital period of the moon is 21.6 days, and the radius of the moon is 1060 km. What is the angular momentum of the moon about the planet? Answer in units of kg m2 /s.
Suppose that the attraction between the moon and the earth were due to Coulomb forces rather than gravitational force. What would be the magnitude of the charge required if equal but opposite charges resided on both earth and moon? Mass of earth = 5.98×1024 kg; mass of moon = 7.35×1022 kg; earth-moon distance = 3.84×108 m.
The distance between the earth and the moon has been very accurately measured by reflecting laser light off special reflectors placed by the Apollo manned moon landings (a) A pulse of laser light is emitted from the earth, reflects off the moon and returns. If it takes 2.56s to complete this journey what is the distance from the earth to the moon? (b) The laser is then made to scan across the surface of the moon creating a spot that...
When Earth and the Moon are separated by a distance of 3.84 × 108 meters, the magnitude of the gravitational force of attraction between them is 2.0 × 1020 newtons. What would be the magnitude of this gravitational force of attraction if Earth and the Moon were separated by a distance of 1.92 × 108 meters?
(10pts) The moon (mm = 7.34E22 kg) and the earth (mε = 5.97E24 kg) have a center to center separation of (4.03E8 m). A. Calculate the acceleration on the moon due to the earth. B. What is moon's average orbital speed, assuming it has a circular orbit about the earth? C. What is the moon's orbital period about the earth in units of days?
