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.
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
Two planets have the same surface gravity, but planet B has twice the mass of planet A. If planet A has radius r, what is the radius of planet B? A) B)r C) We were unable to transcribe this image
Two planets orbit in circular orbits around a star have speeds of 5v(planet A) and 2v(planet B). Express your answers in fractional form, simplified as much as possible. What is the ratio of the orbital radii of the planets? rB/rA = ___/___ What is the ratio of their periods? PB/PA = ___/____
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...
Orbits of four different planets around the same star are shown. The masses of the planets, expressed in terms of the mass M of the smallest planet, can be found in the included table, while the relative sizes of the orbits can be determined from the diagram. Assume that the mass of the star is much larger than the mass of the planets. Rank the period T of the four orbits, from longest to shortest. Orbits of four different planets...
Hi, I want to know how to do qusetion A. Why can write ra2w=rb2w? A planet (mass m) moves in an elliptical orbit around a star (mass m). Let r be the distance of the planet to the star and K the planet's kinetic energy. If the ratio of the angular velocities of the planet at two points, A and B, in its orbit is given by omega_A/omega_B = 4, (a) what is the ratio r_A/r_B? Show working. (b) what...
Note: It should be the same in figure2 (Yellow Page). roblem find the weight of an object/imatter on different planets it is important first to explore the To difference between mass and weight. Mass is a measurement o is the force generated by the gravitational attraction of one o change when we change planets. f the amount it contains and weight This mass does not However, if we went from Earth to Mars, weight would change less gravity than Earth....
what is the weight of an object of mass 10000 g on a planet that is six times the mass of Earth and has twice the radius of earth?
Two very small planets are orbiting a much larger star. Planet A orbits the star with a period TA. Planet B circles the star at four times the distance of Planet A, but Planet B is four times as massive as Planet A. Planet B orbits the star with a period of:
