    It's clearer and brighter, the larger the diameter the more light ray entering so it makes for a clearer, brighter image!

    I would say to pass, perhaps 18 - 23, for a Grade 1, 27 - 34..

    Can't remember, you know on the question where it asked you to find the resistance across the LED? Did you have to minus the voltage you were given from the supply voltage then divide it by the current?

    what did you put for the question about how radioactive source would detect crack, and what source did you say would be used? - i put the one with the shortest half life

    I put alpha as it would not be able to pass through the metal but would be able to pass through the cracks making them easily detectable ;-)

    Does everyone genuinely think it was a lot harder or did we all just get hit with the exam panic and over-think more than we do when sitting Past Papers?

    Also, you know for the distance of the Speed/Time graph, did you just find the area of the rectangle and the area of the triangle and add them together?
    That's what I thought! I was considering if it was just the panic or what.

    And yes for the speed time graph and I got 1080m or something

    Considering we all come from different schools they'll have to lower the pass mark!

    I think for a 2 it will be about 20/50 (40%)
    And for a 1 about 60-65% (30-32.5/50)

    Was a pretty solid paper in honesty.
    Hoping the grade boundaries go down, then I might have a chance of getting a 1 - otherwise I'm guessing it's a scraped 1 or a 2.

    Did anyone else get 15.5m/s for the falling tile question?
    i did, when i asked my friends some of them got 140 odd, so im hoping it was more 15.5

    My physics teacher went over that question a few hours after the exam.. the answer is indeed 15.5.

    did he go over any other ones?
    would u get any marks for knowing Ep = Ek and writing the calculation?


    thanks

    B A D topics, see the question about peek voltage did you get 30V
    and the one about how it couldn't go over 25v, 20V ?
    I know that the 30V answer is correct because I asked my physics teacher afterwards. I managed to get that one wrong. I put 90 as I added the 30 instead of taking it away. :facepalm:

    And I didn't ask about the second one, but that's the answer that I got.

    I'm not sure about the allocation of marks, I think you get 1/3 for Ep = Ek, 2/3 for the correct working and 3/3 for the correct answer. Not 100% sure though, he went through basically the full paper with a few of us.
