{'newtons third law': [0, 0, 1, 0], 'motion': [0, 0, 0, 3], 'internal combustion engine': [0, 0, 1, 0], 'space rocket': [0, 0, 1, 0], 'archery': [0, 0, 5, 5], 'venturimeter': [0, 0, 1, 0]}

The correct answer is option 1, Space rocket.

Newton`s Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that when a force is exerted on an object, the object exerts an equal and opposite force on the source of the force.

In the case of a space rocket, it utilizes Newton`s Third Law of Motion to generate thrust and propel itself forward. The rocket expels exhaust gases at a high velocity in one direction, which creates an equal and opposite force in the opposite direction, pushing the rocket forward. This action-reaction principle allows the rocket to overcome the force of gravity and launch into space.

Alert - The correct answer could also be option 4, Internal Combustion engine. Internal Combustion engine also utilizes Newton`s Third Law of Motion. The engine operates on the principle of converting the chemical energy stored in fuel into mechanical energy. When the fuel is burned inside the engine, it creates an explosion that pushes the piston down. As the piston moves down, it exerts an equal and opposite force on the crankshaft, creating rotational motion that powers the vehicle. This demonstrates the action-reaction principle described by Newton`s Third Law of Motion.
