The working of a rocket depends on Newton's ______ law of motion.

Solution
The working of a rocket depends on Newton’s third law of motion.
Explanation:
Newton's third law plays an important role in the acceleration of fire. When fuel is heated in a fire, a chemical reaction takes place and it burns. Free gases escape through a small hole in the tail on the ground side of the fireball. They exert an equal and opposite reaction force on fire. Due to this reaction force, the fire arrow accelerates forward.

Consider a frame that is made up of two thin massless rods AB and AC as shown in the figure. A vertical force `vec"P"` of magnitude 100 N is applied at point A of the frame.
Suppose the force is `vec"P"` resolved parallel to the arms AB and AC of the frame.
The magnitude of the resolved component along the arm AC is xN.
