Answer:
Newton's Third Law of Motion
Step-by-step explanation:
According to the given condition, the rocket is launched into space and it exhausts gases in the opposite direction of its movement. This condition is an example of Newton's Third Law of Motion. According to that, an action has a reaction but in an opposite direction. More precisely, if an object exerts a force on the other object, the second object will also exert an equal forceback on the first object. This condition satisfies what is mentioned in the statement and thus, it is an example of Newton's Third Law of Motion. Mathematically, it can be written as
I have attached a figure for better understanding.
