I don't quite understand. I read http://chemwiki.ucdavis.edu/Physical_Chemistry/Quantum_Mechanics/09._The_Hydrogen_Atom/Atomic_Theory/Electrons_in_Atoms/Electron_Spin#Principle_Quantum_Number_.26_%28s.2C_p.2C_d.2C_f%29_Orbital and to my understanding a pair of opposite spin electrons can occupy...

A little background: I'm only a high school student with some knowledge on Lewis dot structures. And I don't know much about the s orbitals or p orbitals or whatnot. Why are there lone pairs? Shouldn't the electrons repel each other? Why do we draw them as pairs? For example: carbon dioxide is...

So GR for large scales and graviton for small scales?

So what explanation of gravity should I follow? The distortion of space time or this graviton thingy. Or is it that the graviton is the particle that flows to each object that is gravity? Can these two be united? Because if you're just falling in space-time, what's the need of the graviton?

I did not understand a single thing of that... damn I'm stupid...

So basically... A graviton is the carrier particle of gravity when second quantized? I still don't get it; I just need a brief explanation

a gravitomagnetic field? There's something like that?

I tried looking it up but I can't understand it. Is the graviton some kind of theoretical particle that gives of gravitational waves? I read that it has a 2 spin and is also a boson. And where did this idea originate from? Thanks in advance.

But how can you get Xf if you don't have t? And in the quadratic, I'm not sure which ones would be a, b, or c. I'm thinking in the quadratic formula it's something like. t = x b = Vi a = a c = Xf so it will then look like: at^2 + Vit - Xf = 0 I'm trying to figure this out.

Well I mean average velocity or acceleration. How can I find these variables using algebra if I already have the first formula (s = ut X 1/2at^2)?

So these are the right formulas? But where did they come from? What do they mean?

Not what I meant. I meant how to solve for "t"

Nope, I don't. Can you get these formulas without it?

I'm trying to understand this formula but I'm stuck. I've looked up how to obtain the initial velocity, the acceleration, and time. But all I see are formulas, I don't know how they got it. Can someone guide me through this please? D = Vit + 1/2at2 Vi = (d - 1/2at2) / t a = 2 x (d -...

I've tried solving for time and this was what I got: X= Xo + Vot + 1/2at2 Vo = 0 (it's at rest) Xo = 0 (also at rest) a = 9.8m/s2 X = 71.3m 71.3 = 0 + 0 + (.5 X 9.8 X t2) 71.3 = .5 X 9.8 X t2 71.3 / .5 = 9.8 X t2 71.3 / .5 / 9.8 = t2 √(71.3 / .5 / 9.8) = t t ≈ 3.81s Does this mean...
