yes they are, they are the engines you see on a 747 or even a small Private jet
For thrust. Engines are used to overcome the drag of the airplane.
rocket engines,compared to jet engines
A pulse jet engine is one of the most simple and efficient propulsion devices ever designed. There are three types of pulse jet engines: The valved pulse jet, the valveless pulse jet, and the upright or "Jam jar jet". For complete details on pulse jet engines, go to wikipedia.org and search "Pulse Jet Engine".
yes
No. Jet engines draw oxygen from the atmosphere to mix and burn with jet fuel, and cannot function in a vacuum. Rockets carry their own oxygen, and can travel in the vacuum of space.
The jet engines used jet fuel, not gasoline as the 6 main engines did.
they are now the heart of supar sonic jets we are seeing today . jet engines are used in planes, boats, ships etc. and provide more power than before.
Steel, titanium and aluminium are all used in jet engines.
jet engines only, piston engines still use petrol. jet engines can burn a range of fuel from LPG. to alcohols and diesel. Good quality petrol is valuable to motorists and possibly runs too hot in a jet engine, kerosene has the most suitable properties
For thrust. Engines are used to overcome the drag of the airplane.
Avgas is a common name for fuel used by internal combustion engines in aircraft, while jet fuel is used in jet engines.
There is no actual answer, because a jet is called a jet because it has at least one jet engine.
Fibonacci spiral.
Jet engines were invented before WW2. They were used in a few late war German fighters.

For powering jet engined aircraft and a few other things I don't know
Well yes, assuming if an airplane does not have a jet engine, it would not be called a jet.
