What else can I help you with?
Does a satellite need fuel to keep moving?
Yes, a satellite in orbit requires fuel to make adjustments to its trajectory or maintain its position. However, satellites in geostationary orbit can maintain their position without fuel because they orbit above the same location on Earth.
I can see satellite with telescope?
While it is technically possible to spot satellites with a telescope, it can be challenging due to the fast speeds at which satellites orbit the Earth. You would need a telescope with a high magnification power, precise tracking capabilities, and clear viewing conditions to have a chance of spotting a satellite. It's recommended to use resources like satellite tracking websites or apps to help locate satellites in the sky.
A projectil is projected vertically upwards from Earth at what height above the earth's surface will the force on the satellite due to the Earth be reduced to half its value at the Earth station?
(1/2)Gm/R2=Gm/(R+h)2Where:G is the gravitational constantm is the mass of the EarthR is the Radius of the Earthh is the height above the Earth where Gravity is 1/2 surface gravityCanceling Gm from both sides gives:1/2R2 = 1/(R+h)2inverting to make things simpler:2R2 = (R+h)2taking the square root of both sides:sqrt(2)R=R+h(sqrt(2)-1)R=hthe sqrt(2)=1.4142135623730950488016887242097(sqrt(2)-1) = 0.4142135623730950488016887242097so h=0.4142 RThe required height is 0.41 times the radius of Earth.
What is angle period of satellite?
The angle of the satellite period, depends on where the satellite is positioned. When you figure out where the satellite is you position the angle to be where and what you need.
What is synchronous orbit?
A synchronous orbit is an orbit whose period is the same as the period of rotation of the parent body. If the orbit is circular, the orbiting body remains above the same point on the surface of the parent; if it is elliptical, the orbiting appears to move forward and backward in its orbit, returning to the same point each (sidereal) day. Stationary orbit around the Earth is called geostationary orbit or Clarke orbit (after science and science fiction writer Sir Arthur C. Clarke). Such an orbit is frequently used for communications satellites, since it results in the satellite appearing to be fixed in the sky so that ground antennas do not need to move to track it. A geostationary orbit is about 22,240 miles (35,800 km) above the equator.
Names of series of american satellites launched in earth?
You can not launch a satellite "in" earth or indeed "into" the Earth. To launch a satellite you need a rocket.
A satellite is projected vertically from an Earth station at what height above the Earth's surface will the force of Earth's gravity on the satellite be only half its value at the earth station?
To answer this question we need to know either the height of the Earth station above the Earth or the gravitational acceleration of gravity present at the Earth station initially.Solving without these values:(1/2)Gm/R2 = Gm/r2whereG is the Gravitational Constantm is the mass of the EarthR is the radius of the Earth Station from the center of the Earth.r is the radius of the satellite where gr=1/2ge2R2 = r2SQRT(2)R=r
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)
What is the significance of the curvature of the Earth in relation to satellite communication?
The curvature of the Earth is important for satellite communication because it determines the line of sight between the satellite and the ground station. Satellites need to be positioned at a certain height above the Earth to maintain line of sight and ensure effective communication. If the Earth were flat, satellites would not be able to maintain a consistent connection with ground stations around the globe.
How can you find live satellite images in Google Earth?
To find google earth images, you need to go to google first and click on the satellite tab that will show you the views from a satellite rather than the street view or the walking view.
Why would anyone need a satellite phone ?
A satellite phone provides better services and a higher coverage area. A satellite phone can offer coverage that includes the entire earth.
does The moon orbits around Earth, making it a?
An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them.
What is the escape velocity for satellite?
If it is close to Earth, it would need a speed of 11.2 kilometers per second to escape from Earth.
Does a satellite need fuel to keep moving?
Yes, a satellite in orbit requires fuel to make adjustments to its trajectory or maintain its position. However, satellites in geostationary orbit can maintain their position without fuel because they orbit above the same location on Earth.
Does earth's gravity do any work on satellite revolving around it?
NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)
How high is England above sea level?
not that high above sea level, does that help, thnks, you need to get a life
Why must scientist carefully calculate and control the speed of a satellite that they intend to orbit the earth?
i dont know but i need the answer.
