    I got 65.8

    I actually really liked that paper. I couldn't get the 51km question (I kept getting 49) but I might have actually got 95%+.

    But I'm not looking forward to PH5...
    I can't see many people looking forward to PH5

    In PH5, at least the boundaries reflect the difficulty of the paper, so that's one reason to look forward to it.

    What did you think of the paper? :holmes:

    finding the mass of the planet in the star planet system, the question said earlier that the mass of the planet was much smaller than the star...

    Does anyone have any good resources for B fields? my teacher rushed that bit so I'm a bit confused about how hall probes investigate steady magnetic fields and why current carrying conductors exert a force on each other thank you!

    S-Cool has some good explanations, though probably not detailed enough, so check the spec just to be sure: http://www.s-cool.co.uk/a-level/phys...agnetic-fields.

    Does anybody/their teacher have ideas about possible case study questions? It's not a very nice one this year, so I'm hoping for a decent number of simple calculations, showing homogeneity in terms of units, etc.

    Calculating the age of the universe
    Finding the escape velocity
    Deriving the third equation using the other 2

    These are a few my teacher mentioned

    That would be a massive help, if you could share them (I'm a private candidate, so don't really have any class notes).

    Thanks very much - it's very kind of you to share your notes.

    On another note - do you know which dimension in a Hall probe we are supposed to take as d? Is it the one parallel to the B-field? Thanks in advance.

    I'm pretty sure that is t and the perpendicular one is d.

    Yeah, I eventually figured it out by looking at the picture in the revision guide. Thanks, though!

    Thanks, they did. Although, could you take another picture of the very last attachment (the one that's printed as opposed to handwritten). It's just that I tried to zoom into it but it got all blurry. :/
    Thanks again.

    No worries at all - you've been so helpful.
    Yeah, I understand it now. Hope your maths exam went well/goes well (not sure if you've had it yet)! :woo:

    Okay here it is, it isn't as important as the others, its just a time line we had to make about the different people contributions to the discoveries

    How are you feeling for tomorrow ?
