012 10.0 points Planet X has a mass 4.86 times that of the Earth and a radius 2.83 times the radius of the Earth What is the ratio of the acceleration due to gravity on the surface of Planet X to the acceleration due to gravity on the surface of the Earth?
A planet has twice the mass of Earth and twice the radius of Earth. The free-fall acceleration on this planet is equal to what?
The radius of a planet is three times that of Earth and its mass is nine times that of Esrth. The acceleration due to gravity on this planet is
Planet X has 20 times the mass of the earth and 3 times the earth's radius. It orbits star Y at a distance of 8 AU, where 1 AU is the earth-sun distance. Star Y has twice the mass of our sun. (a) What is the orbital period of Planet X in years? (b) An astronaut has an earth weight of 120 lbs. What is her weight on the surface of planet X?
A spherically symmetric planet has 2 times the Earth's mass and twice its radius. If a jar of peanut butter weighs 12N on the Earth, how much would it weigh on the surface of this planet? depends if it's Skippy creamy or super-chunky peanut butter.
The acceleration due to gravity on the surface of a planet is nine times as large as it is on the surface of Earth. The mass density of the planet is known to be seven times that of Earth. What is the radius of this planet in terms of Earth's radius? RE Rplanet t
