The correct answer is: A. Newton’s Third Law.
Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that when a rocket pushes exhaust gases out of its engine, the exhaust gases push back on the rocket with an equal and opposite force. This force is what propels the rocket forward.
Newton’s First Law of Motion states that an object in motion stays in motion and an object at rest stays at rest unless acted upon by an unbalanced force. This means that if a rocket is not moving, it will not start moving unless something pushes it. Similarly, if a rocket is moving, it will not stop moving unless something pushes it in the opposite direction.
Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object. This means that the harder you push on an object, the faster it will accelerate. Similarly, the heavier an object is, the harder you will have to push to get it to accelerate.
Archimedes Principle states that the buoyant force on an object is equal to the weight of the fluid that the object displaces. This means that if you put an object in water, the water will push up on the object with a force equal to the weight of the water that the object displaces. This force is what keeps objects afloat.
In conclusion, the correct answer to the question “Rocket works on the principle of” is A. Newton’s Third Law.
