Can Newton's laws of motion explain the movement of electrons in atoms? If possible, can someone explain how?

(I tried to think along the line of perhaps centrifugal/petal forces, but they don't orbit (according to bohr's incorrect model) in one single plane, do they? So im really lost. Help please)

Hint: A concise + short explanation and links will give u 10 points=)

i also want to know if it is true that if you are totally healthy that swallowing liquid mercury isnt bad for you at all. It is just inhaling the vapors that'll kill you because it gets into your lungs.

Please help me settle an office bet. The hallway outside my office is 133.5 feet long, and the ceiling is 8 feet high. Can a major league baseball player (specifically, Ivan Rodriguez, the catcher for the Detroit Tigers) throw a ball and hit the wall at the other end of the hallway without it bouncing on the ground first? I say yes, and have an expensive bottle of irish whiskey riding on it. Any help you can provide with proving me right (I hope) would be much appreciated.

let us assume two rocks both at same cliff with the same mass are pushed down.one falls down on an elevated platform just below the cliff and another all the way down.
the force in both the cases will be the same as the mass is the same and the acceleration due to gravity is also the same as f=ma.but the damage caused to the platform by the stone which falls on it is surely less when compared to the damged caused by the stone which falls all the way down on the ground below the platform.why is this so?

Senario: A person has committed a crime and the dies few days later. That criminal was an organ donor and some organs are donated. Would the person who received the vital organ / bone / soft tissue / hair etc then possibly be in the frame for the crime, should the police run DNA /tissue samples etc?

I know the answer to this. I just want to see what others think

Yeah2..
I just gotta know:

Why are mountains snow-capped and it's a lot colder higher up...?

After all, being higher up means being closer to the sun, doesn't it?

If I spin around really fast and stop, everything else still spins around me. This must mean I am a very important person since I am at the center of this spinning universe, right?
