Free Notes For A Level Physics 9702 By Sir Hunain Zia. (2) use mirror scale. A consistent unit must be quoted with the appropriate number of significant figures. Suppose the values of k you calculate come out to be : Percentage difference between these values of k is: % difference = (k2-k1)/k1* 100 = (0.461-0.456)/0.456 * 100 = 1.09% (which is <10%). The Best Physics AS and A Level Notes. Hi! OMGGG I love this web Im having paper 3 Physics test tomorrow and this help me a lot. A nice table should have these features: Largest possible range is required. In that case, your significant figures for the calculated quantity (in the example, value d), must be equal to the smallest number of significant figures in the raw data or 1 more than that. and accompanying notes are also included on the CD-ROM.Written and .

As you can see now, I described above HOW I am going to vary the independent variable, and HOW I am going to measure the dependent variable. Error: An explanation of some physics that does not answer the question will not score marks, even if the explanation is correct. We have updated the A Level Past Papers section with the Latest A level Phyics papers including the May/june 2017 and Oct/Nov 2017. In the example paper, the equation given in question 2 is: It can be arranged into linear form like this (t is measured, hence a dependent quantity, and resistance (nR) is varied, hence an independent quantity): Using the power rule of logarithm on the right side, we get. (4) Clamp rule / ensure rule is vertical using a set square on the bench 100% Money Back Guarantee. You will lose marks for the wrong units, however, no marks will be deducted for the subsequent parts. Have any questions? By comparing it with linear form, we know that, n/d = m = gradient, and B = c = y-intercept. If any paper is still missing, please report using the Contact Us! Error: Proof of repeated readings is mostly required in marking schemes. Using the same paper for explanations:(May/June 2018 Paper 5 Variant 2). Keep in mind! y is dependent variable, x independent variable, c is point where line touches y-axis(a constant),and m is gradient of graph. Sociology 9699 Past Papers.

So first thing first, know how many variable you have to measure and/or calculate so you coulddraw appropriate columns. Credit is not given for suggestions that should be carried out anyway, such as repeating measurements and calculating average or avoiding parallax errors by looking at an instrument square on. Course Hero is not sponsored or endorsed by any college or university. Personally, I recommend using small crosses instead of dots (points), because blobs (points with diameter > 0.5 small square) are not accepted. This paper will consist of two questions of equal mark value (15 marks each) based on the practical skills of planning, analysis and evaluation. Or: Check read-off ofintercept directly from graph.
