if two electrons collide would their spin change from counter clockwise to clockwise?

Spin is a property of the electron like it's charge and it's weight.  I don't think it would change from a collision.\n\nhttp://en.wikipedia.org/wiki/Spin_%28physics%29

That would be E; nonmagnetic.  Any idiot could figure that out

If you are at the North pole, it would settle on one of the other north poles.  Actually, there are three of them.  Closely spaced but technically three.   \n\nIf you were at the magnetic center point, the needle would probably dip down a little and lose all directional reference. Probably would not "spin", but would be subject to randon movement.

Layer, orbital (azimuthal), magnetic and spin.\n\nNo two electons in the same atom can all the 4 numbers the same: be in the same layer, in the same orbital, sharing the same magnetic and spin value.

Yes, if it's converted to energy.  E=mc^2

The electrons are not attracted to either pole of the magnets. However the deflection of the electron beam follows the same principle as that of a motor, i.e. the Lorenz Force right hand rule (i.e. the deflection of the electron beam is at right angles to both the magnetic field and the direction of flow). Therefore the magnets at the top and bottom of the tube move the beam left and right, while the magnets at the sides of the tube move the beam up and down.

False, because the binding energy increases steeply till iron and again reduces. So I would require enormous accelerators to transmute the element with Z>20.

the answer is probably b (I will get to the "probably" part later). the path the electron takes would be bent by the magnetic component of the field (producing a curve) and it will be pushed by the electric field changing the direction toward a specific direction (along the electric field), but movement will all take place in a plane which is along the original direction of propogation IF the electric and magnetic fields are at 90 degress to the original projection. \n\nFor different orientations of the fields, it is also possible to get helixes for the movement path, which do not apply to any of the answers.\n\nAlso, for specific initial velocities, electric and magnetic fields, it is  possible to obtain a straight path.\n\nIf the electromagnetic field is varying with time, there cannot be an answer to this question, since the path can be totally erratic.

no.its the force produced due to the movement of other particles(electrons).so..

It's an interesting idea, but subatomic particles that do not have electrons are also affected by time dilation (cosmic rays for instance).  And electrons do not literally spin around a nucleus (as far as we can tell) there is a potential for it to be anywhere in a give shell at any given time.

Only a limited answer:  For the special case where M = m, there are just 2 collisions.  After the first collision, V = 0 and v = V's initial value.  In the post-reflection collision the opposite exchange occurs.

Quantum leaps are only possible between orbitals that overlap each other and the probability of leaping is proportional to the amount of overlap (actually since the wave functions are complex numbers it's slightly more complicated than this).\n\nYou can see what the orbitals look like and how they would overlap in the section "visualizing the hydrogen electron orbitals" in the first reference.\n\nDon't worry about the non-overlapping parts of the orbits moving faster than light. Thats just how quantum mechanics works. Einstein didnt like this and wrote a paper about it in 1935 (second reference), but he turned out to be wrong.

Imagine you have have a source that emits pairs of electrons. Quantum Mechanics now states that one can not describe the behaviour of each electron separately, but only the pair as a whole. \nFor instance, if the spin of the first electron is pointing up, than the other must point down and vice versa.\n\nBut QM also states that the exact state of an electron (up or down) can only be known if we measure it and not before. But once we measure the spin if the first electron (say, it's up) than we know immediately the spin of the second one too, although it might be lightyears away. And if some distant observer measures that spin he will find that it is down. So somehow, the information of the fact that we performed a measurement on the first electron, has travelled to the second electron. And at a speed, faster than light.\n\nThis is the EPR paradox.\n \nBut the story is not complete yet.\nSpin must be measured relative to an axis, be it x, y or z.\nBell's equations described how a measured along one axis on the first electron is related to measurements along the two other axis performed on the second electron.\n\nSee here for a more complete explanation:\n  http://en.wikipedia.org/wiki/EPR_paradox

Sign conventions.  Mass is always positive, and that's the deciding factor for angular momentum.  Magnetic moment involves charge, and electrons are negatively charged, so it ends up being anti-parallel.  But, this is just an arbitrary convention, so don't get too worked up over it.  Yes, it's important for keeping your ps and qs straight in doing physics, but it's not of any major physical significance.  \n\nIf we'd decided to call electrons "positive" and protons "negative", then the magnetic moment for an electron would be parallel to the angular momentum.

yes all the time. \nwhen the two bullets collide, if the speeds are the same then they will explode on impact with a canceled out net force of 0. it will be like the bullet hit a stone wall. the stronger bullet collided with a wek bullet would push it in its direction and the weak one will explode before the strong one. I think......

Here the concept is U'll decide the logic 1 nad 0 based on  spin of electrons...currently HP is working on it...if they come up with big result, it'll b a revolutionary change n da VLSI industry
