I'm working on a project for a space habitat, and I want to have the math to back it up. Sorry if some of these seem obvious or too simple, but I'm here to learn. By the way this is not homework, it's just something I do in my spare time. And if you have the links where I can learn more about these things, just provide those and I'll learn on my own.
1. Let's say you have a circular object, which can spin around an axis (a metal rod, for example) in space, all power by an electrical motor (so because of EM). Is it possible that because of the difference in mass and the fact that it's in space, that the rod spins inside the circular object and not the other way around (the circular object spinning around a rod).
2. I know that air is made of 70% nitrogen, but we only use in the breathing process O2 and the plants only use CO2, so what is the role of the nitrogen. Is it to make the air (the whole compound) lighter so we can breathe it, or what?
3. How do rockets propel themselves in space? On earth, the blades simply push back the air, but in space there is no air. And can inertia a planet's orbit be used for moving forward (Be on a course forward, engage on a orbit, spin around, the break off the orbit and start moving independently but in a different direction).
4. Is the temperature in space constant, and if so is it 0 K? (If it's something like 1/1000 of a degree above 0 K it's not that relevant, but interesting nonetheless)
