    physics unit 4 2013 paper discussion

    I got 0.05A too, but the current in 10ms i couldn't so the question about finding the resistance after it was left blank :(

    Messed up big time! :cry:

    physics unit 4 2013 paper discussion

    Wow guys, you haven't started discussing the answers yet. Well, I made silly mistakes, the question about the amp-clamp, like daymm!!! I made up stuff there about the frequency and stuff. Couldn't do the initial current question, and the rate of increase of voltage was the gradient of the graph...

    OMG LOL! I left it, half way through, I attempted it like 3-4 times!

    Screw it! Yup, it was that bad. Physics Unit 5 is my only hope, please Allah, have mercy!

    Guys!!! please write an email to EDEXCEL for complaining about the paper leaking!!

    Email now before the grade boundaries are set otherwise we'll be the ones suffering the most. This is my complain, have you got one? To Whom It May Concern It is outrageous and downright unfair to students who did the Mathematics paper fair and square. I was one of the students who did the...

    My Complain!!!! I'm seriously angry right now! Send your complains too. To Whom It May Concern It is outrageous and downright unfair to students who did the Mathematics paper fair and square. I was one of the students who did the replacement paper therefore I humbly request you to set different...

    How was Physics 6PH08 Alternative to practical ?

    Wrote the same thing since human reaction time is 0.1 s, 0.01 s will be accurate.

    How was Physics 6PH08 Alternative to practical ?

    Question 1 part (a) was 1, the measurement of volume was 2 I think, and percentage uncertainty in volume was 3

    No wonder why I hate them!

    How was Physics 6PH08 Alternative to practical ?

    Nope, for metre rule 1 mm, vernier 0.1 mm and micrometer screw gauge 0.01 mm.

    How was Physics 6PH08 Alternative to practical ?

    Thanks, I think I mentioned that. After joining all the points in the graph I got it as 1.66 Hz.

    How was Physics 6PH08 Alternative to practical ?

    I wrote amplitude increases, hope they treat it as the same :( For the diameter, since it was all 25.9 measured with a vernier, so I took the estimated uncertainty for one reading (0.1), and it had to be multiplied with 2. It was three marks so I doubt it should be zero, not sure!

    How was Physics 6PH08 Alternative to practical ?

    I really don't remember, damn it! Well insha Allah it'll be right, by the way what did you get the resonant frequency from the graph? And how to make it accurate? Plus, what happens when the frequency from the generator is same as the natural frequency?

    How was Physics 6PH08 Alternative to practical ?

    I wrote light intensity, do it in a dark room to ensure the only light source is the bulb as the distance between the bulb and the LDR was to be the only variable, makes sense? I don't remember the gradient at all o_O It was point something

    How was Physics 6PH08 Alternative to practical ?

    My density was 7400 to 2sf. For that, I wrote finding mean reduces percentage uncertainty. Hope it makes sense, was a guess.

    How was Physics 6PH08 Alternative to practical ?

    There is an A* guys for unit 6B, i did a few dumb mistakes too, like for vernier caliper i took te precision as 0.001 :( Well, for the volume I used pie(d^2/4)h. AWESOME!!! Alhumdolillah got k and p right then :D

    How was Physics 6PH08 Alternative to practical ?

    Hey, well I got 7400 (2sf), for the graph I didn't get all the points on the straight line, and the gradient was p right? And the y-intercept was ln k?

    People who have given SAT's..

    Muhammad Bin Anis: For IBA you can skip the admission test by scoring well in sat 1 (1500) according to the requirement in IBA otherwise do well in the admission test, best to visit the website and search through. For good universities like LUMS, GIKI, COMSATS and IST, even if you do give sats...
