A satellite is at an altitude of one of earth radius. How does the gravitational force on the satellite compare to the force if it were on the surface of earth?

Since the distance from the Earth's center is doubled, the force will be reduced by a factor of 4.

What is a geostation satellite?
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
At what height from the surface of the earth the total energy of the satellite is equal to its potential energy at a height of 2R from the surface of earth?
This question cannot be answered because:the total energy of the satellite includes its kinetic energy and that depends on its orbital speed. This is not specified;it is not clear what you mean by "potational": is it a typo for rotational or potential?what is R? The radius of the earth or the height of the satellite or some other measure?
What is Venus's gravitational pull in meters per second squared?
The acceleration of gravity on or near the surface of Venus is 8.87 m/s2 . . .about 91% of its value on or near the surface of Earth.
Why are satellite orbits depicted as sine-wave shapes?
The sine wave represents 360 degrees or a full circle. As the satellite revolves 360 degrees around the earth in its orbit this is how it is represented on a flat surface.
If a satellite orbiting just above the surface of the Earth orbits in about 1.5 hours then at about how many Earth radii from the Earth's center must a satellite orbit to have a period of 24 hours?
You can use Kepler's Third Law to calculate this.
Does a satellite in low tilt at low altitude show more of the earths surface than one in high tilt at same altitude?
a satellite in a low tilt at a low altitude can see earth better.
What is the altitude of the lowest flying satellite?
the lowest flying satilite is DAN 100kl above the earths surface
Doubling the distance between an orbiting satellite and the earth will result in what change in the gravitational attraction between the two?
One Fourth as muchNote:When you talk about gravitational forces, the "distance" you're working withis the distance between the object and the center of the Earth. That's about4,000 miles more than its altitude above the surface.
How does the gravitational pool of the moon compare to that of earth?
An object on the surface of the moon weighs about 1/6 as muchas it weighs on the surface of the Earth.
What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
How would the colors in a satellite image of an area compare with a color photograph of the same area?
The satellite image will have more realistic surface of the Earth compared to photograph.
How would the colors of a satellite image of an area compare with a color photograph of the same area?
The satellite image will have more realistic surface of the Earth compared to photograph.
How is air pressure effected by altitude?
With a higher altitude, there is a lower air pressure. This is caused by gravity pulling the gas molecules of our atmosphere closer to its surface. when the molecules are farther away from the Earth's surface the gravitational pull is weaker thus making the atmosphere thinner higher up and thicker closer to the surface.
How does the air pressure at the surface of the earth compare to the air pressure at about 7 miles above earth?
The greater the altitude, the lower the air prassure.
What is one way to compare two masses?
Compare their weights when they're both in the same gravitational environment ... on the surface of the Earth, for example. Under those conditions, their weights will be directly proportional to their masses.
What is potential energy called that depends on height?
Gravitational potential energy - it depends on the distance from the centre of gravity, so on Earth it depends on the height above the Earth's surface
What is a landsat satellite?
A satellite that observes Earth's surface.
