Question

What is a multi-staged rocket? What are its advantages?

Answer 1

Hint: A rocket is an aircraft/ spacecraft or a vehicle which is basically used to launch anything from the earth to space. The material to be launched is known as ‘payload’. We can explore different parts of the universe using rockets. Usually the cost of a single rocket is in billions, thus there are only a few organizations working on rockets.

Formula used:
Angular dispersion between red and violet rays is given as:
$\theta = (\mu_V - \mu_R)A$
Where A is the angle of prism, $\mu_R$ and $\mu_V$ are refractive indices for red and violet rays respectively.

Complete step by step answer:
The organization producing rockets has to be very precise about the functioning and efficiency of rockets. We have two types of rockets: Single staged and multi staged. Single staged rocket is nothing but just a solid propellant on which the payload is placed and sent to space.
But in this type of rocket, we can’t send more load and we can’t send the load to far more places. Hence to increase the efficiency of rockets, scientists came out with multi staged rockets. In this type of rocket, we have multiple stages of rocket. Usually we have a luxury of two or more stages before final payload.
Advantage- The advantage of this type of rocket is that due to multiple stages of launching, every time a new stage is being launched, the older part which has its fuel empty gets detached. This decreases the overall weight of the rocket and hence the speed eventually increases.

Note:
The launch of a rocket is based on Newton’s laws of motion. The main fact behind it is that the fuel is ejected from the bottom part of the rocket at a very high rate so that the rocket experiences an upward thrust (due to momentum of fuel) and this thrust when gets greater than the weight of the rocket, the rocket gets launched.
