A planet of mass m = 3.15 × 1024 kg orbits a star of mass M = 5.55 × 1029 kg in a circular path. The radius of the orbit is R = 2.05 × 107 km. What is the orbital period Tplanet of the planet in Earth days? 0.00111 Tplanet = Incorrect days

If a planet with 1.5 times the mass of Earth was traveling in Earth’s orbit, what would its period be?

Let gM represent the difference in the gravitational fields produced by the Moon at the points on the Earths surface nearest to and farthest from the Moon. Find the fraction gM/g, where g is the Earths gravitational field. (This difference is responsible for the occurrence of the lunar tides on the Earth.)

The Sun has a mass of approximately 1.99 1030 kg. a. Given that the Earth is on average about 1.50 1011 m from the Sun, what is the magnitude of the Suns gravitational field at this distance? b. Sketch the magnitude of the gravitational field due to the Sun as a function of distance from the Sun. Indicate the Earths position on your graph. Assume the radius of the Sun is 7.00 108 m and begin the graph there. c. Given that the mass of the Earth is 5.97 1024 kg, what is the magnitude of the gravitational force on the Earth due to the Sun?

The orbit of Earth’s moon has a period of 27.3 days and a radius (semi-major axis) of 2.57 ×10-3 A.U. = 3.85 × 105 km. What is the mass of Earth? What are the units?

O Macmillan Learning A horizontal meter stick has a mass of 211 g. Three weights ride on the meter stick: 255 g at 46.5 cm, 191 g at 82.5 cm, and 197 g at 92.7 cm. At what location on the meter stick would the system be in balance if it were suspended there? location: cm

A moon is orbiting its planet in UCM. If the planet has a mass of 2.6 x 1026kg and the moon is orbiting the planet at 6.69 x 10³m/s, then what is the radius of the moon's orbit? r = unit

A planet of mass m = 6.35 x 1024 kg orbits a star of mass M = 1.85 × 1029 kg in a circular path. The radius of the orbit is R = 8.25 x 107 km. What is the orbital period Tplanet of the planet in Earth days? Tplanet = days

The rings of the planet Saturn consist of particles of rock and ice which orbit the = 5.7 × 104ºkg. Suppose a particle has a planet.
