The rocket pushes the exhaust gases backward and there is an "equal and opposite reaction" that pushes the rocket forward.

Answer: Option (b)

<u>Explanation:</u>

Rocket is one of the propulsive unit functions similar to air-filled balloons and it works on the principle of newton thirds law of motion.

This law states that for every action there will be an equal and opposite reaction.

The fuel is burned inside the rocket and it releases the exhaust gas and these gases create an impact of force that propels the rocket into space.

Explain how transverse waves can be produced on a rope. Then describe how pieces of the rope move as waves pass.
andrew-mc [135]
Transverse waves can be produced on a rope by moving one end of the rope up and down.The movement causes motion in the particles that make up the rope and the rope itself becomes the medium. The particles move perpendicular to the propagation. The movement also causes crests(highest point of the wave) and troughs (lowest point of the wave) which move along the direction of propagation.
