Saturn has a mass that is 95 times that of Earth and a radius that is 9 times that of Earth. What is the first cosmic velocity for Saturn in kilometers per second?
Suppose that Planet X has 5 times the radius of the Earth and and 16 times Earth's mass. What is the ratio of the escape velocity on Planet X divided by the escape velocity on Earth?
· The mass of Jupiter is 317 times that of earth and the diameter of Jupiter is 11.25 times that of earth. Calculate the value of "g" on the surface of Jupiter. (30 points)
Jupiter is 300 times more massive than the Earth and 10 times the diameter of the Earth. An astronaut lands on a planet that is the mass of Jupiter but the same radius as the Earth. On this planet the force of gravity is: a) The same as on the surface of Jupiter b) Between that on the Earth and the surface of Jupiter c) The same as on the Earth d) A little bit higher than on the the...
Consider a white dwarf with the same mass as our sun. What would its radius need to be (in Earth radii) to have an escape speed of 7000 kilometers per second?
Jupiter has a mass of 1.9 x1027 kg and a radius of 69940 km. Calculate the acceleration due to gravity on the surface of Jupiter, in meters per square second. What will be the force between Jason and the Jupiter if Jason's mass is 69 kg?
Consider a white dwarf with the same mass as our sun. What would its radius need to be in Earth radii) to have an escape speed of 7000 kilometers per second?
Please answer the entire question step by step 4) The escape velocity on the surface of a planet is given by 2GM V= R 1 S where G = 6.67 x 10-11 m² kg :-2 is Newton's gravitational constant, M is the mass of the planet, and R is the radius of the planet. The escape velocity is the velocity you have to thrown an object so that it does not come back down (better hit the gym!). Write v...
The sun's mass is roughly 333,000 times that of the Earth. A white dwarf with the mass of our sun would be roughly the size of the Earth. What launch speed would be required to put an object in orbit around a white dwarf in kilometers per second?
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?
