    I see, so you treat AC as if it's resistors combined in parallel? And voltage dissipated across CB first? despite the direction conventional current?

Q6 http://papers.xtremepapers.com/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_s10_qp_22.pdf And when it asks for line of best fit, do you draw a curve or a straight line of best fit? (Silly question...

    How do I answer, when a question (I've seen many times in paper 2) asks for a comment? For example in this paper; http://papers.xtremepapers.com/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_s04_qp_2.pdf Q7(c) it asks to comment.

    I see... thanks! So if the fringe seperation (x) is increased -> the diameter of light falling increases -> area of light falling increases -> intensity decreases (y)

    Sorry if my explanation was not clear, but yes the answer is proton. But the question was that whether the particle that have the same value in the nucleus of isotope is either electron or proton. So that correct answer would be proton because proton is located within the nucleus, but electron...

    Nuclei contains only proton and neutron. (proton + neutron = nucleon) The electrons are the one orbiting the nuclei. So in physics its better to define isotopes to be the atoms that have the same number of protons but different number of neutrons in their nuclei.
