A newly discovered planet has twice the mass and three times the radius of the earth. What is the free-fall acceleration at its surface, in terms of the free-fall acceleration g at the surface of the earth? a. 1/9 g b. 2/3 g c. 3/4 g d. 4/3 g E. None of these
A newly discovered planet has a mass of 4.0 x 1023 kg and radius 4000 km. What is the free fall acceleration at the surface of the planet?
A new planet is discovered in a neighboring solar system that has twice the mass, but half the radius of Earth. How does the strength of the gravitational field on Earth (gE) compare to the strength of the gravitational field on the newly discovered planet (gN)? A. gE= gN B. gE= 8gN C. 2gE= gN D. 8gE= gN The answer is D. But can someone show me how to use the equation mg=Gm1m2/r^2 to show this relationship. Please indicate the...
A new Earth size planet has been discovered in a distant star system. The planet has six times the mass of Earth and has a radius of twice the radius of the Earth. Do NOT mix or change system of units! There is an equation in the posted handout for solving this problem. If you do not use it you will only receive 1 point for this problem no matter your answer. What is the acceleration due to gravity on...
Assume that a Spherical Planet Of Radius R, Has a Uniform Mass Density (Per Unit Volume) Distribution Throughout, Of Value Po. Also, Assume that There Is a Massive Dust Cloud In the Rest Of the Universe, Which Decays Exponentially In Radius, r, Away From the Surface Of the Planet, Where the Mass Density Varies As ρ(r) = Po exp| | | |, For r2R- a) Using the Integral Form Of Gauss's 6. Law, [n.gda--4πGJsoh', And Spherical Coordinates (Specifically Using the...

Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1.1 m and finds that it makes 500 complete oscillations in 1,121 s. What is the gravitational acceleration g on the surface of this planet?
points A newly discovered planet is in a circular orbit around a distant star with an orbital period of 400 Earth days. The planet also rotates on its axis, making one full rotation every 4.00 Earth days. The radius of the planet is rp = 7.00 × 106 m and the radius of the planet's orbit about the star is r 7.00×1011 m. My Notes Ask Your Tea Determine the ratio of the radial acceleration, due to the rotation of...
Planet X has half the radius of the earth, and also half the density. What is the acceleration due to gravity on the surface of planet X?
In a newly discovered exoplanetary system one planet orbits its star in 56 days with an average orbital radius of 107,588,122 kilometers. It is observed that another planet in the same system has orbital period of 373 days. What is its average orbital radius of the second planet? Express your answer in kilometers, use scientific notation and round the coefficient to two decimals. In a newly discovered exoplanetary system one planet orbits its star in 57 days with an average...
