Answer;
A. rocket engines are not dependent on oxygen from the air.
Step-by-step explanation;
- The main difference between turbojets and rocket engines is the fact that rocket engines are not dependent on oxygen from the air.
- Jet engines and rockets work on the same principle. They produce thrust through an internal pressure difference and, as explained by Newton’s Third Law of Motion, eject exhaust gases in an equal and opposite direction.
- However, jets get the oxygen to burn fuel from the air and rockets carry their own oxygen, which allows them to operate in space.
- Another difference is the fact that normally Jet engines have two openings (an intake and an exhaust nozzle). Rocket engines only have one opening (an exhaust nozzle).
