OCR Advancing Physics G492 ~5 June 2013~

What was your gradient. Mine was 2.7 which is in the right range. The right answer will probably be allowed anything from 2 to 3.

Are you sure the gradient wasn't in a range around 10 times higher?, as the majority of my friends all got values around 25 or 26. I got 26.4 btw

Haha. I genuinely meant 27.7. So yeah seems right.

ok not sure how people managed to get a value close to 9.8 for the "calculate g" question, as I rearranged the equation to get v^2/2.8sin(theta) = g, but had no idea which value to use for theta, so i ended up getting something like 14ms^-2

I got 9.71 I think? Was that the choc in the microwave question?

No, it was the last part of the trolley question.

For the last question in Section C, did you guys get 2.94 x 10^8 and uncertainty 0.3 x 10^8. Uncertainty has to be 1 sf.

I couldnt get the uncertainty how did you get that may I ask? I got the 2.94x10^8 though

For the last question in Section C, did you guys get 2.94 x 10^8 and uncertainty 0.3 x 10^8. Uncertainty has to be 1 sf.

Exam was quite tricky but section C was quite easy. I reckon:

A: 70
B: 65
C: 58
D: 51
E: 45

And full UMS cap: 90

These boundaries are ridiculous.

What grade did you get then?

I got an A, with 279 UMS! Don't ask how, I'm in complete shock. How about you?
EDIT: Never mind, just scrolled up. Well done!

Well done What subjects are you going to be doing for A2?
