प्रश्न
Write scientific reason.
Satellite launch vehicles are used to place satellites in their specific orbits.
उत्तर
- The working of the satellite launch vehicle is based on Newton’s third law of motion.
- The launch vehicle uses a specific type of fuel which when burned, produces a gas. The gas expands due to its high temperature and is expelled forcefully through the nozzles at the rear side of the launch vehicle. As a result, a thrust acts on the vehicle, which drives the vehicle high into space.
- The structure of the launch vehicle and the fuel to be used is decided by the weight of the satellite and the type of satellite orbit.
- In this way, satellite launch vehicles are used to place satellites in their specific orbits.
