Two planets have the same surface gravity, but planet B has twice the mass of planet...
Two planets are orbiting around the same star. Planet A has four times the mass of planet B. Planet A is located twice further from the star than planet B. When comparing the force of gravity affecting both planets, what is the value of the following ratio: FG on A FG on B O A) 4 B) 2 C) 1 D) 1/2 O E) 1/4
A planet has a mass of M1, a radius of R1, and a density of Q1 A second planet has a mass of M2, a radius of R2, and a density of g2. This problem will explore the relationships between the surface gravities (g1 and g2) of the planets depending on the relative sizes of their masses, radii, and densities. Assume that planet 2 has X times the mass of planet 1, or M2 - XM1. The densities of both...
A hypothetical planet has 3 times the mass of Earth and twice the radius of the Earth. What is the surface gravity on this planet? r = Rplanet g = GMplanet / r2
The weight of an object is the same on two different planets. The mass of planet A is only 60 percent that of planet B. Find the ratio rA/rB of the radii of the planets.
The weight of an object is the same on two different planets. The mass of planet A is only twenty four percent (28%) that of planet B. Find the ratio r_A/r_B of the radii of the planets.
Satellite A has twice the mass of satellite B, and circles in the same orbit. Compare the two satellite's speeds. The speed of B is twice the speed of A. The speed of Bis half the speed of A. A. The speed of Bis one-fourth the speed of A. The speed of B is equal to the speed of A. The speed of Halley's Comet, while traveling in its elliptical orbit around the Sun, O is constant increases as it...
A hypothetical planet has a mass 3 times that of the Earth and a radius twice that of the Earth. Calculate the value for acceleration due to gravity near the surface of this hypothetical planet.
Using the formula for gravity, find the force of gravity on a 1.2-kg mass at Earth's surface. (The mass of Earth is 6 x 10M kg, and its radius is 6.4 x 106 m.). Express your answer to two significant figures and include the appropriate units. く1024 kg) and the Moon mass-74x 1022 kg Find the force of gravity between Earth (mass-6.0 is 3.8 x 108 m. The average Earth Moon distance Express your answer to two significant figures and...
Four planets, A through D, orbit the same star. The relative masses and distances from the start for each planet are shown in the table. For example, Plant A has twice the mass of Planet B, and Planet D has three times the orbital radius of Planet A. Which planet has the highest gravitational attraction to the star and why? Planet A, relative mass is 2m, relative distance is r Planet B, relative mass is m, relative distance is 0.1...
Planet X has free-fall acceleration 8 m/s2 at the surface. Planet Y has twice the mass and twice the radius of planet X. On Planet Y g = 2 m/s2 g = 4 m/s2 g = 8 m/s2 g = 16 m/s2 g = 32 m/s2
