    Astrophysicists, what are your guesses for the 6 marker? I hope it's something really nice like fusion occurring in stars lol

    I think comparing radio with optical would be a good comparison

    Can someone explain why cathode rays are produced in a discharge tube?
    Electrons collide with the few air particles which excite the electrons in the particles. When the electrons in the air particles de-excite back to ground state they release photons which is why you see a beam of light. The particles coming from the cathode (the electrons) must be negative because they move from the cathode to the anode.

    No. We can never presume anything. There are two ways AQA could have thought:
    1: Damn! Our papers were stolen again, better whip up a paper at the last minute and make it ridiculous because we're so so angry
    2: Quick! Write a paper at the last minute, who cares what goes into it! Which would be the slightly easier outcome. But probably full of mistakes :clap2:

    But basically, we have no idea what it'll be like.
    Although if it means anything, I know some people who did the BIO5 exam today that was a re-write and apparently it was horrible.
    I did that exam today, I thought it was fine. I reckon they won't make this paper significantly harder, maybe slightly more obscure questions...

    Sorry guys, i think i spammed the poll. It was my first time voting so i think it was my fault. I didn't even know that would happen. I'm sorry for any inconvenience caused.

    Yeah and that can be displayed as I=k x 1/x2 then sub in K=Io/4pi and that makes the equation...

    I=(Io/4pi) (1/X2)
    which leads to I=Io/4pi(X)2
    Ok thanks.. I didn't even realise k was actually Io/4pi in the first place.
