hello *We are able to explain why current is induced when piece of wire inside MF is pulled with force F[pull] ( wire is thus moving perpendicular to MF or at some angle ): *We can also explain why even if piece of wire is at rest, but instead MF is moving, a current...

hiya I'm having some problems understanding concave mirrors and their reproduction of actual object. 1) Can you show me some proof as to why all rays of light from the object converge at the same point ( image point )? 2) I'm having hard time understanding how person...

greetings 1) 2) 3) 4) 5) cheers

hiya I would appreciate if the following questions be answered with words, not numbers ( I like analogies :) ). Else, don't bother since it won't help much. EF ... electric field MF ... magnetic field 1) 2) 3) thank you

I'm confused why my textbook would explain how loss of potential energy depends on the distance the force acts on a charge, and then in next chapter it would without any explanations ignore all of what it was said in the previous chapter and and declare that loss of potential energy does not...

hiya 1) Some quotes from physics tutorial site: The above all makes sense. But this is where I get lost: Wouldn't it be more correct if instead we said: *The kinetic energy charge has was transformed from charge's potential energy, and this kinetic energy gets lost as charge goes...

That is too advance for my little brain. I prefer if things are explained in simpler terms. In short, answers need to be dumbed down

When electron is at position P!, it creates electric field EF1 When electron is at position P2 it creates EF2 But no matter how fast electron is when it is at position P2 there is only one electric field existing, which is EF2. EF1 and electric forces created by EF1 stopped existing the...

I only vaguely know what you mean by this. I'm guessing this isn't the same as calculating average speed or something similar? Anyways, my reasoning is : electron orbits nucleus extremely fast and such even though test charge near this atom might feel EF field when electron is at...

uh, I meant the effect of electric force is instant. So by the time electron is at position P2, EF1 is long gone and thus EF2 and EF1 can't cancel each other out. This is why I think the following can't be true:

For the following to be true atom must have same amount of protons and electrons? You mean because electron orbits the protons it changes its position with great speed in such a way, that while it does create EF1 in time T1 ( at time T1 electron is at position P1 ), it then changes...

But how does that affect atom's surroundings (in terms of electric field this atom creates etc )? Net force can be explained using vectors...is that also true for net charge? So an atom containing 6 protons has mass 12 u?

I only vaguely understand what you are saying. I know about terms such as "net force" or "net electric force", but am not quite sure how to interpret "net charge" Is that also true for atoms of other elements?

hiya 1) 2) 3) thank you

I hope I don't come out sounding like a prick, but you corrected the text I quoted but in doing so you didn't explain my initial two questions. You did answer the third one though. :) And I have a textbook, but it doesn't go into any more detail than the text on that site.
