Explain the use of multistage rockets in launching a satellite.

Explanation

An artifical satellite is launched with the help of a mutlistage rocket. When the rocket is fired, the fuel of first stage rocket stars burning. This makes the rocket to each the desired height with a denfinite speed. Now the first stage is detached itself from the remaining roacket and the fuel of second stage rocket stars burning. This will make the desired direction of rocket and wull increase the height as well as the speed of rocket. When the fuel of second stage rocket is burnt completely, this stage is also separated from the remaining rocket. Now the fuel of last stage rocket stars buring. This will give the desired height and speed to the rocket.
When the desired height is attained, the body placed at the nose of rocket is projected horizontally with the desirad speed by automatic mechanical arrangement. (All these calculations are done in advance.) Now the body will start orbiting around the earth with a denfinite period and becomes a satellite of earth.
