Principle check: jet propulsion used for ships and aircraft Statement: The principle of jet propulsion is used in driving ships and aeroplanes. Assess the correctness of this engineering statement. Choose the correct option.

Difficulty: Easy

True — the statement is correct
False — the statement is incorrect
True only for aircraft, not for ships
True only for ships, not for aircraft

Correct Answer: True — the statement is correct

Explanation:

Concept
Jet propulsion relies on Newton’s third law: thrust is generated by expelling mass at high velocity in the opposite direction.

Applications
Aircraft: turbojets/turbofans eject high-velocity gases to produce thrust.Ships/boats: water-jets eject a high-speed water stream to push the craft forward (waterjet propulsion).

Final Answer
True — the statement is correct.
