The Earth has a mass of 5.97 * 1024 kg and the Sun has a mass of 2.00 * 1030 kg. If they are separated by a distance of 1.50 * 108 km, what is the force (in N) between the Earth and the Sun? (Enter your answer in scientific notation: 1.23E12 means 1.23 * 1012)   Repeat the previous problem using centripetal forces. Assume the Earth travels in a perfect circle around the Sun, with masses and distances given above, and takes 365.25 days to complete a complete circle. What is the centripetal force (in N) acting on the Earth? (Think about why and by how much the answers to these two questions differ.)

Astronomers have observed a small, massive object at the center of our Milky Way Galaxy. A ring of material orbits this massive object; the ring has a diameter of about 17 light-years and an orbital speed of about 100 km/s. A) Determine the mass  M  of the massive object at the center of the Milky Way Galaxy. Give your answer in kilograms.Express your answer in kilograms. B) Give your answer in solar masses (one solar mass is the mass of the sun). Express your answer in units of solar masses. C) Many astronomers believe that the massive object at the center of the Milky Way Galaxy is a black hole. If so, what must the Schwarzschild radius  RS of this black hole be? Express your answer in meters.

The planet Jupiter rotates every 9.9 hours and has a diameter of 88 846 miles. If you’re standing on its equator, how fast are you traveling

If you are sitting at the equator on Earth, what would your average speed be knowing that the radius of the Earth is 6.37 x 106 m? What would your acceleration on Earth be?

a) An object weights 4000 N on planet Alpha. Planet Alpha has 8 times the mass of planet Beta and 4 times the radius of planet Beta. What will the object weight on planet Beta?   b) A 60 kg person is sitting on a bathroom scale while riding on a Ferris Wheel. The Ferris Wheel has a radius of 9 m and the person's speed is 3 m/s. Find the scale reading when the person is at the bottom of the motion.

The mass of a certain planet is 3.00 x 1026 kg. (a) The planet has a moon whose mean orbital radius is 2.90 x 108 m. What is the period of this moon? (b) The planet has a second moon whose period is 2.30 x 106 s. What is the mean orbital radius of this second moon? eBook

The astroid belt of our solar system is located between the orbits of Mars and Jupiter. An astronomer is studying an interesting asteroid and has determined that one orbit around the Sun takes it 2.83 years. How far is the asteroid from the Sun? The following constants may be helpful. Earth's distance from the Sun = 1 AU = 1.5 x 1011 m MSun = 2.0 x 1030 kg G = 6.67 x 10-11 N m2 / kg2 1 year = 3.15 x 105 s A)1.5 AU (2.25 x 1011 m) B) 2.0 AU (3.00 x 1011 m) C) 2.5 AU (3.75 x 1011 m) D) 3.2 AU (4.80 x 1011 m) E) 4.8 AU (7.20 x 1011 m)
