Space shuttle in orbit (farther from Earth's center!) Space shuttle on launch pad Earth

Io, one of the satellites of Jupiter, has an orbital period of 1.769 days and the radius of the orbit is 4.22 × 108 m. Show that the mass of Jupiter is about one-thousandth that of the sun.

Assume that you have two objects, one with a mass of 10 kg and the other with a mass of 18 kg, each with a charge of –0.017 C and separated by a distance of 2 m. What is the electric force that these objects exert on one another? Answer in uits of N.

Two objects are sitting 6 meters apart. If they are moved so that they are 3 meters apart, this will double the gravitational force between them. True or False?

(II) You are explaining to friends why an astronaut feelsweightless orbiting in the space shuttle, and they respondthat they thought gravity was just a lot weaker up there.Convince them that it isn’t so by calculating how muchweaker (in %) gravity is 380 km above the Earth’s surface.

help Find the gravitational force between a cruise ship full of ducks with a mass of 11 x 10^8 kg and a giant octopus with a mass of 2 x 10^6 kg if they are 13 meters apart.

Use Newton's law of universal gravitation to determine the force of gravitational attraction between the Earth (mass 5.97 x 1024 kg) and a satellite of mass 152 kg orbiting at a distance of 4.26 x 106 m from Earth's center.
