Question

Explain why a single stage rocket cannot be used for launching satellite in an orhit round the earth. OR​

Answer 1

Answer:

the satellite 'escapes' the Earth's gravity and drifts into space. In any case, it would not become a satellite of the Earth. Therefore, a single stage rocket is of no use and lower thrust by the second-stage gives the correct horizontal velocity to the satellite to put it into a stable circular orbit.
