your answer is correct

Well...I don't quite see the answer in these choices. Because conducting electrons in a wire move due to an electric field with a certain kind of velocity called drift velocity.

anonymous · Answer

Since I have not yet studied or learned about drift velocity, I would guess that you don't see the answer because you are seeing the question and its answer in an advanced way. Keep in mind this is eighth grade physics. But, if you were to eliminate three choices and leave one choice as your answer, which would it be, considering what I just told you? :)

anonymous · Answer

I know that I would easily eliminate answer choices A. and B. because they are silly and make no sense. So, of the two left, which would you pick?

I'd say A. But remove the atoms. Lol.

anonymous · Answer

But it cannot be A. because I can't change the answers. XD
