    Can someone tell me if I get 3 marks in this question? Explain how the line spectrum of hydrogen provides evidence for the existence of discrete electron energy levels in atoms. Ans. Each atom will have different energy levels which indicate the transition of an electron from a higher to a...

    Thanks a bunch! :) but I didn't get the last part why would it be a scattered one? Only one line will pass through the cloud and two dark lines will show absorption. What about the scatter?

    There's this question in MJ 11 P41, where a transformer is given and the secondary coil is connected to a load resistor, and the question says "use faradays law to explain why the P.d across the load and the e.m.f of the supply are not in phase? How do I use faradays law in this?! Faradays law...

    Oh right!!!! Thanks a lot for clearing it up! I got confused when I saw the MS say that it's wrong because the temperature is in degree Celsius not kelvin.

    You do get 3 marks but refer to point masses rather than just stating masses. Because one mark is for stating point masses in all the marking schemes

    PHYSICS PAPER4!!!

    Above 54 below 60 usually. As I said check the grade thresholds along the paper you do

    Physics: Post your doubts here!

    It is October/November 2012 paper 41. I can't link it because the site is not working. And one other thing, kinetic energy (temperature) of gas molecules only and only increase if the particles collide with more speed right? It has nothing to do with how often the molecules collide, for example...
