    ****.

    **** OFF ******* EXAM

    why did i find that so hard.

    I thought it was reasonable, apart from that **** off long 6 marker at the end. I missed the last 4 marks as well. Nothing extraordinarily hard though, just damn long. I struggled to finish section A in 45 minutes. What were the hardest questions, do you think?
    And some of the people I aforementioned said they found it hard. So I'm pleased about that.

    The 6 marker wasn't that long was it? it was only two specific points... unless there was another 6 marker i somehow missed....:confused:

    It was that, but I spent a bit too long on it :emo:

    It was ok, reckon I've lost about 10 on the multiple choice, missed out two 2 markers and a 1 marker and I reckon I've lost 10 more marks on the other questions. So hoping Ill have about 50/75.

    do you reckon saying laminate the core to prevent eddy currents would be accepted? there's that, and i worry i didnt explain it well enough: i said that the eddy currents oppose the change that caused them so some of the power is diverted into creating eddy currents.

    Some answers I remember, anyone got similar?

    Multiple choice:

    - The time period had r^3/GM in it
    - An oscillating mass would return to its natural frequency after driving force removed
    - 1000uF vs. 100uF capacitor was 10xenergy, 10xcharge stored
    - displacement is pi/2 out of phase with velocity?

    Paper:

    - velocity was 2.21 in Q1
    - centripetal acceleration found by GM/r^2
    - Transformer increasing voltage to 12V - no effect on time to 90% discharge, quadruple energy stored
    - 23.2s time constant
    - 6x10^-5 current
    - gpe was gp times m, for that 'state the relationship'
    - Kinetic energy graph was 0 at 0, max-positive at T/4, 0 at T/2, max-positive at 3T/4 and 0 at T. I ended up with two parabolas but not sure about the shape. Is it like a sin^2(x) curve and if so how were we meant to know that shape?
    - I got £4.20 for the cost, was that "about £4" or did anyone get closer?
    - How much were we meant to write for the very first part; describe energy changes in pendulum? I wrote about 3 times as much as the space required, what would the two marks be?

    I got similar to you but i missed out the last page, i saw the last question and just wrote something random like saves money over a long period of time but takes too long to switch it on again.

    Got ass raped by the multiple choice questions though, everyone in my class found it hard too.

    I got all your multiple choice answers and most of your Section B's, although I put something different for the time for 90% discharge but you are right I think, I didn't do the cost because it was taking me too much time. I also wrote tons for the first part of section B.

    I wrote loads there too. It is rather hard to explain briefly. Hope I wrote what they wanted though.

    Anyone hazard a guess of the grade boundaries (raw marks) for this? What percentages are usually A's, B's, C's, etc in physics A2 exam? And don't tell me 80% for an A because that would surely not be the case....

    i think the paper is apparently easier than the examination-style question after each chapter in the textboook. There is some tricky questions in the those asking which one is correct/incorrect statement., Overall it is a "test of knowledge" paper, at least most answers can be found in the book directly.

    Looking at the previous Unit 4 (which was a little different), average of 70 for an A, 60 for a B. The hardest Unit 4 paper was even 65 for an A. None were above 75 for an A.

    Oh right I thought it was always 80% for an A :/. Things aren't too bad then!
