Ok, thanx for help.

So the spring transfer the whole force like solid object would? It does make sense, altought I found it somewhat unitnuiteve and I just wasnt sure.

Nothing, for the purpuse of this question.

Thanx for answer. Yes, the spreing compresess. For example we have a 1 kg object with no spring. How would we calculate the force when the spring is between object and weight?

We put object on weight ang get a mass. What would that mass be if we put a spring between object and weigt, so that the spring woul shrink to half its original size?

Would it be posible to meausre(theoreticaly) magnetic filed and electric field for example if a single photon wolud be travling trought space?

Could we measure volume of light?

I read on the internet, I can't renember where exatly. So is this wrong? Does light have volume?

For light it is said it has no volume and also it it waves of electric and magnetic field. But for electric and magnetic field you need space? So can they both be at the same time?

Ok so what is than the source of electric field in conducting wire? Not the voltage of battery but the electrons in the wire?

Ok, than the question is how wire chanes the field?

No I meant electric field. I know there is potencial diffrence between ends, but ther is also electric field insede wire. And electric fieled is a field so it is evrywhere, just sometimes its value might be zero.

I have a question what does create a electric filed inside coducting wire? And is it the same field trought the whole wire? Thanx for answers.

Ok thanks for answers.
