Let's tackle both:
Rocket Engine:
* Basic Principle: Rocket engines work by expelling hot, pressurized gas out of a nozzle, creating thrust that propels the rocket forward.
* Combustion: Fuel and oxidizer (usually liquid oxygen) are ignited in a combustion chamber, creating extremely hot gas.
* Expansion: The hot gas expands rapidly through the nozzle, accelerating as it exits.
* Newton's Third Law: For every action, there is an equal and opposite reaction. The expelled gas pushes against the rocket, and the rocket pushes back, generating thrust.
* Types of Rocket Engines: There are many types, including solid-fuel rockets, liquid-fuel rockets, ion engines, and more, each with its own advantages and disadvantages.
Rocket Raccoon:
* Fictional Character: Rocket Raccoon is a fictional character from the Marvel Comics universe.
* Origin: He's a genetically engineered raccoon with enhanced intelligence, agility, and combat skills.
* Abilities: Rocket is a skilled pilot, engineer, weapons specialist, and strategist. He's also a master marksman and a very skilled fighter.
* Personality: Rocket is known for his cynical personality, sharp wit, and penchant for sarcasm. He often acts as the "muscle" and the "voice of reason" for the Guardians of the Galaxy.
