The orbital speed of a satellite will depend on the strength of gravitational field at the orbital radius. Consider the following situations. Which identical satellite will be travelling faster in each case? Why? a- Satellite A orbits the Earth at twice the orbital radius of Satellite B. b- Satellite A orbits the Sun at the same orbital radius that Satellite B orbits the Earth.(

Yes or No? Is it possible to have two satellites are in circular orbit around the Earth at the same orbital radius, but with different orbital speeds (in m/s)?

In a geosynchronous orbit, a satellite stays above the same point on Earth because it takes exactly one day to go through one orbit of 2(pi) radians. If the radius of this orbit is 42,100 km, how fast is the satellite traveling around the Earth? pick the one equation and define the relevant knowns and single unknown.

In 2000 , NASA placed a satellite in orbit around an asteroid. consider a spherical asteroid with a mass of 1.50 * 10^16 kg and a radius of 10.0 km what is the speed of a satellitie orbiting 5.90 km above  the surface ? express with appropriate units what is the escape speed from the asteroid (express with appropriate units)

= 400 kg with their centers 8 meters apart. If you In the simulation, start with mị = 200 kg and m2 want to increase in the gravitational force between the two masses by the greatest amount, should you double the mass of m2 or should you halve the distance between the masses? In one or two sentences, explain which option would create the greater increase in the gravitational force and why.

A 150-kg satellite is in a 310-km altitude stable circular orbit around earth. What is its orbital kinetic energy? a) 4.46*107 J. b) 4.46*1011 J.                                c) 4.46*109 J. Data: mass of earth = 5.97*1024 kg, radius of earth = 6380 km, G = 6.67*10-11.

Two satellites are in circular orbits around the earth. The orbit for satellite A is at a height of 409 km above the earth’s surface, while that for satellite B is at a height of 835 km. Find the orbital speed for (a) satellite A and (b) satellite B.

The spaceship Palomino approaches star XYZ to study it by going into a circular orbit of radius 1.0·107 km. All that is known initially is that a planet orbits this star at a distance of 1.86·108 km taking a time of 271 Earth-days to make one full orbit. At what speed should the ship orbit the star at? What is the gravitational acceleration on the Palomino due to this star's gravity? (c) What is the ratio of the mass of star XYZ with that of the Sun? (MSun = 1.987·1030 kg)

A satellite is orbiting earth  at a distance of  3.1 X 105 m above the surface of the Earth. What is its orbital speed? (G = 6.67 X 10-11 Nm2/Kg2; M of Earth = 5.97 x 10 24 kg; Radius of Earth = 6.37 x 10 6 m)
