yes
Its closer to the earth. Can say much more without know the velocity of the satellites
No. Satellites ARE falling. But they are also moving "sideways", and so quickly that by the time the satellite has fallen to the Earth, the satellite has continued AROUND the Earth, and missed!
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
It means that it moves around the planet, along a path (orbit) that has the shape of an ellipse.

Not very much, I would say. There is no work being done in this situation so there's no change in kinetic energy. So the satellite's speed remains constant. But we already knew the speed was constant. Perhaps I'm missing something.
keep safe
It was the first human-made satellite, (launched from Russia on Oct. 4, 1957), to orbit the Earth. A space probe leaves the orbit of Earth and goes off into distant space. Sputnik only left Earth's orbit to burn up in the upper atmosphere on Jan. 4, 1958.
To answer that, we have to agree on where space starts; then we can say how far away that is.Let's say that space starts where the air is so thin that a satellite can stay in orbit, withoutslowing down enough to fall down to earth.That's about 160 miles straight up from where you are right now. Everything farther than that is 'space'.
"Media is here to stay" is the correct phrasing because "media" is a collective noun referring to a singular concept, so it should be paired with a singular verb "is."
no it is not correct acoording english grammer
In order for a satellite to stay in space and not fall to earth, it has to move in orbit round the earth. Many satellites and the International Space Station are in low orbit and at that distance above the earth orbit the earth in a couple of hours or so. However, if the orbit is around 26000 miles up, then at that distance the time it takes for a satellite to freely orbit is exactly one day or 24 hours. This means that the satellite is always above the same spot on earth, as the earth also takes 24 hours to rotate. Thus, if we could see the satellite in the sky it would not move across the sky like the International Space Station but it would stay in the same place in the sky. This means that they can be used for communication - when you telephone, say, from Europe to the USA then the signals are received by these satellites, amplified and relayed across the world to the receiver of the call. As the satellites are in the same place in the sky all the time, you can call at any time of the night or day. However, if the satellite moved across the sky in low orbit you would only be able to use it when it was in the sky - in other words you could only telephone for a few minutes at a time and then have to wait until it was back in the sky again. Similarly, these satellites are used for navigation in sat-navs. As the satellite is always in the same point in the sky, it can work out your position at any time of the night or day. The term 'geostationary' comes from 'geo' meaning 'earth' (as in geo-graphy, geo-thermal etc) and 'stationary' - meaning not moving i.e. the satellite is 'not moving above earth'.
