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:
Two very small planets are orbiting a much larger star. Planet A orbits the star with a period T. 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 A) T/4 B) 8T C) 4T D) T E) 16T
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...
7. Planet A and planet B orbit around the same star. Planet A is thre times as far away from the star as planet B is. We can write the previous statement as a ratio: TA/TB 3, where r stands for the planet's distance to the star. What is the ratio of the period of planet A around the star to the period of planet B? In other words, labeling period as T, what is TA/TB? Give your answer with...
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...
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
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...
4. A space probe is orbiting Planet A. It is then moved into an orbit around Planet B. Planet B has three times the mass of Planet A, and the probe’s orbit around Planet B is twice the radius of the orbit it had around Planet A. What is the ratio of the orbital period around Planet B to that around Planet A? A. 2.0 B. 0.62 C. 1.6 D. 0.82 E. There is not enough information to answer.
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 = ___/____
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.
