    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    Yes, that's right. The highest points were the antinodes. I just don't exactly remember the distance between successive ones. :/

    CIE is running out of questions.

    Twice* every year.

    The distance between two antinodes was 0.17m, punk.

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    Yes, exactly. And if I remember correctly, the distance between two successive antinodes was 17cm=0.17m. So, 0.17x2=0.34m. And hence, 340/0.34=1000Hz.

    Let's just wait for the mark scheme then. :)

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

    TanQ was inversely proportional to v^2 so the equation we'd get would be tanQ=k/v^2. Comparing it with y=mx+c would give c and hence, the y-intercept to be 0. Doesn't that mean it should be passing through the origin? :/

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    500 Hz was NOT the answer, I repeat. The idiots who got 500 probably made the mistake of thinking it was a uniform stationary wave, taking the distance from the start to the end of the wave to be 0.68m and the distance between three nodes. Lol, I say. It was a PART of the wave, and so the...

    LOL. I would suggest you to revise your concepts before arguing.

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

    The gradient was positive, and in Q1, it WAS passing through the origin.

    AS Physics P2 GT?

    It's good to see how confident you are of your abilities. And you know, it is always wise to KNOW before you speak. I finished my paper in sufficient time, but seems like most people here and other people I know could not. If geniuses like you were the only ones who appeared in this paper, I say...

    How do we get our overall grade in exam?

    I am also confused in this regard. Do they just add up the marks we obtained in all the components or calculate each component's marks according to the weightage allotted to it, e.g. if I get 70 in Chem P4, would they just add 70 or calculate the percentage by applying 46/100*70 (P4 carries 46%...

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    At A, the ball has both kinetic energy and potential energy which is converted to the internal energy of the atoms of the ball and ground when it hits the ground, which is again converted to kinetic and potential energy at B.

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    Since the errors in the raw data were to 1 significant figures each, the error of 8.9x10^-5 had to be written as 9x10^-5, i.e. 1 significant figure. You would probably lose only the last 1 mark.

    And anybody remember the answer to the last part of question 2? The energy changes?

    Sorry if my memory is playing tricks on me, but wasn't the distance between two antinodes 51-34=17cm?

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    The value of C was 1.04x10^-3 and the error was 9x10^-5.

    Wasn't the distance between two antinodes on the graph 17cm?

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    In a stationary wave, the distance between successive nodes and antinodes is lambda/2 while that between a node and an antinode is lambda/4.
