Question

In a rocket, a large volume of gases produced by the combustion of fuel is allowed to escape through its tail nozzle in the downward direction with the tremendous speed and makes the rocket to move upward. Which principle is followed in this take off of the rocket? a) Moment of inertia b) Conservation of momentum c) Newton’s first law of motion d) Newton’s law of gravitation​

Answer 1

Answer:

b) conservation of momentum

Answer 2

In a rocket, an expansive volume of gasses created by the combustion of fuel is permitted to elude through its tail spout within the download heading with huge speed and makes the rocket move upward. b) preservation of energy is the guideline is taken after in this take-off of the rocket.

Explanation:

• The Law of preservation of force states that for two or more bodies in a disconnected framework acting upon each other, their add-up to energy remains steady unless an outside drive is applied.
• Therefore, the force can not one or the other be made nor be destroyed.
• The Law of preservation of energy is a vital result of newton's third law of motion.
• Newton's third law states that "for each activity, there's a rise to an inverse response".
