Direction: Read the passage carefully and answer the questions that follow: Any heavenly body evolving round a planet is its satellite. For example, moon is a satellite of earth. It is a natural satellite. However, man has created artificial satellites which also evolve around the earth. These satellites are used for various purposes. The artificial satellites keep orbiting the earth. If a satellite is orbiting at a height of about 400 km. or less it loses, its velocity in course of time due to friction with dust particles.it then gradually spirals towards the earth and burns up on entering the earth's atmosphere. Satellites have electronic transmitters that send signals to the earth. So, once they have completed their mission and are about to be abandoned, scientists switch off the electronic transmitters. This is done to prevent the disrupting of transmissions from other satellites. Many countries have uploaded their satellites in space for better telecommunication purposes. The International Telecom Union requires all satellites to be pushed up before they are abandoned, so that they do not fell back on to the earth.
