    How did Physics M/J '17 52 go?

    I will try my best too in P4 bcuse tht ppr is grade changing ppr. p5 chem all you need to do is get your hands on as many pprs as you can and see marking scheme and if you have time to read examiner reports DO IT!!! and I made long notes and short notes for my chem A2, so i will be revising...

    How did Physics M/J '17 52 go?

    nahhh bro I wrote how I measured the change in freq however I didnt told them how to vary it.

    you can't get 85-95 mrks in P4 bcuse usually on 60 there is an A. but when i was solving pprs myself I got 80-85 marks.

    How did Physics M/J '17 52 go?

    oh tht i know signal generator is used but as i told you it was tricky so I forgot to write it but they will give marks for how to measure freq after you changed it. so i got tht good. also they clearely stated motor and motor over time gets hot. and yours is right too. I am getting atleast...

    How did Physics M/J '17 52 go?

    People can we discuss question number 1 in detail cause Q2 we will prolly get ecf and will get around 10-12 marks who got their Y-intercept wrong. Also Question 1 had alot of diff points to gain marks, I will start with what I wrote. ☆Freq is IV. ☆r is DV. ☆mass to be constant also the distance...

    buddy I hope so bcuse I spent alot of time on P4. its going to be very tough after seeing P5.

    How did Physics M/J '17 52 go?

    sensei I myself was confused seeing the question so I analaysed it carefully and applied F=mrw^2(4pie^2×frequency^2) which helped me alot solving it.

    most of us got this right.

    yup.

    straight line. always when doing Q1

    you my friend defo getting A*. MA SHA ALLAH.

    How did Physics M/J '17 52 go?

    yeah you just had to tell tht about K.

    How did Physics M/J '17 52 go?

    man this is confusing, i hope I get ecf atleast. Gonna get A/B now. or in worst case C.

    o man.

    How did Physics M/J '17 52 go?

    i guess my y intercept is wrong. 3 marks gone. *cries*

    How did Physics M/J '17 52 go?

    no not sure about question 1, I took frequency Independent variable. and I varied it by using oscilloscope. I kept mast constant. I kept decreasing the freq which after rotation, my mass started to move more farther away from center. which tells me that r=1/f

    How did Physics M/J '17 52 go?

    i guess it was 1.5% y intercept 18.36 sth and 0.2 uncertainity.

    How did Physics M/J '17 52 go?

    gradient same. E also close enough. Q wrong.
