    Economics, Accounting & Business: Post your doubts here!

    That was a good paper. I did Q4 and Q5. btw, I've never heard of CFI. I just explained it using the aggregate expenditure line. Also, how much did you guys right for the GDP question. I kept repeating the same things.

    Well, I don't understand how you get D grades when you are getting 80% at home. I think you are either not understanding the questions during the exam, or maybe the examiner doesn't understand what you are trying to say, because I had to read what you wrote twice to get what your question was!

    HOW WAS PHYSICS PAPER 5 PPL ? HOW WAS YOUR EXAM ?

    I wrote N Hz^-2 m^-2 or something like that...

    HOW WAS PHYSICS PAPER 5 PPL ? HOW WAS YOUR EXAM ?

    I'm sure they'd give you the mark. And, for missing the units, you will only get 1 out 2 marks, provided your answer is correct.

    HOW WAS PHYSICS PAPER 5 PPL ? HOW WAS YOUR EXAM ?

    Yeah mine too and so were my friends so something around those answers must be correct.

    HOW WAS PHYSICS PAPER 5 PPL ? HOW WAS YOUR EXAM ?

    The question said "the speed of the wind" NOT the speed of the balloon, so, I don't think anyone really knows how to measure the speed of wind unless you use a anemometer, but I didn't know that :/

    Can someone please help! I don't get how to calculate the errors when you log something. Like, take these values as an example: I (current) = 2.6 +/- 0.1 . Calculate log(I) with the absolute errors. How would you do it?? It came in this paper, Q2b)...

    But why did But why did you multiply (0.389^2 I ) x (0.331 ?

    So basically, you just draw a graph similar to that one, but each individual peak is every 20µs and the lwhole waveform takes 200µs to complete?

    Yeah, isn't it the one where the frequency stays the same, but the amplitude varies with the displacement?

    I still don't get it. Like, do you mean, draw the carrier frequency separate?

    Could someone please help me with the graph on Q10 c) ? How would you draw it? http://www.xtremepapers.com/papers/CIE/Cambridge%20International%20A%20and%20AS%20Level/Physics%20(9702)/9702_w07_qp_4.pdf

    Um, I really can't say. I've answered a lot of Gravity questions, and motion in a circle questions as well. You can't predict what will come. Have you read the application stuff? Sometimes there are 6 - 8 mark questions in that!
