Why do communication and weather satellites always appear at the same place in the sky?

That is because those satellites are in geostationary orbit, which ensures that they stay always above the same spot on the earth's surface. This is possible only if the satellite is placed in orbit at about 22,000 miles above sea level.

Can rainbows never appear?
Rainbows cannot appear if there's no rain and sun afterwards. Rainbows root word is rain so for that reason rain has to appear in this event. But sum rainbows can appear in different weather? Rainbows cannot appear with out rain. Rainbows cannot appear with out rain. ----
does the moon always appear full somewhere on earth?
yes it does
When viewed from above rainbows are what shape?
Rainbows are an optical illusion, they are not "real". You cannot view them from above; they will always appear the way they appear from the ground.
What kind of weather does a cumulues cloud bring?
Cumulus clouds typically indicate fair weather. They are fluffy and white with a flat base and appear during stable atmospheric conditions. However, they can develop into cumulonimbus clouds, which bring thunderstorms and potentially severe weather.
Is a satellite at 110 degrees West higher in the sky than a satellite at 119 Degrees West?
It depends upon where you are in relation to the satellites. If you are east of the 110 satellite, then yes the 110 appears higher than the 119. If you are west of 119 then it would appear higher than the 110. If you are in between them, the closer one will appear higher.
What is the inclination of a satellite to the earths equator?
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
How fast do UFO travel?
UFOs are merely unidentified objects that fly or appear to do so. They may be weather balloons, meteors, satellites or other objects. Their speed is dependant on what they are. What they are not is alien space craft.
What is the name of the orbit that allows satellites to orbit the earth but yet appear stationary?
The Earth orbit in which satellites appear to be stationary is called the, "Geostationary Orbit". Some call it a synchronous orbit.
What are true of a geostationary weather satellite except that it?
Orbiting the Earth above the equator is true of geostationary weather satellites and they have infrared sensors to transmit images of the entire hemisphere continuously. All of those things are true except that while they are moving in orbit they appear motionless.
Can you see satellites?
Yes, they appear as slowly moving stars in the night sky.
Which of the following is NOT likely to appear on a map?
Horizon
Where is each satellite positioned in the sky?
Satellites appear at different locations in the sky based upon the task that they must perform. Satellites that are in "low" Earth orbit, such as the GPS and some weather sats orbit the earth at only a few hundred miles above the surface. They move in relation to a fixed position on the Earth, though they follow well-defined orbits (hopefully). Satellites in "Geostationary" orbits, such as communication and other weather sats, are approximately 40,000 miles off the surface of the Earth more or less over the equator. Because of the distance and the speed at which they orbit, they appear stationary in the sky to a fixed observer. This is useful for satellites that broadcast continuous streams of data, like satellite television. Finally, there are satellites that are even farther out from the earth. These are used for scientific purposes. An example is SoHo, a satellite that studies the Sun, or COBE, the satellite that mapped out the cosmic background radiation. A new space telescope set to launch in 2011 (ish?) will actually orbit the sun, though will remain locked in a gravitational point in tandem with the Earth (called a Lagrange Point).
Why is it not sensible to put communication satellites into lower orbits?
There is only one orbital altitude where the satellites do not appear to move; that is the 23,500 mile "geo-synchronous" orbit where communications satellites typically reside. Lower orbits would cause the satellites to orbit more quickly, requiring that the terrestrial antenna be equipped to follow it as it passed over, and to be able to switch to a new satellite once the first one was below the horizon. Since satellite TV antennas are large and not easily movable, a geo-synch orbit makes more sense.
Why does the universe appear dark when seen in the photo from satellites?
There ias no atmosphere to scatter the sunlight like on earth.
Which is not likely to appear on a map A poles B legend C longitude lines D satellites E cardinal direction?
Satellites. They move, so they cannot be printed on a map. Additionally, "satellites" is the only option that physically exists; the other choices are concepts, not objects.
