Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2I wrote along the same lines, but i drew the young's modulus type experiment using a spring, instead of it hanging from above, i also didn't say saw draw a graph and working the gradient, i said divide the force by the change in length by using f=kl, how many marks would i get ?? thanks a whole bunch(Original post by iAre Teh Lejend)
You would definitely be in the 5-6 mark category.

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Antiphase will get you a mark. almost in phase wont :P(Original post by adam17)
Do you think I'd get the mark for putting almost in antiphase for the first one, and almost in phase for the second one?
Dont ask me why I put that I have no idea why I did :') -

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2No. you had to be specific. one was 1/2landa out, an theother was 7/8landa out. (or you could have used angles, such as pi radians and 1 3/4 pi radians phase difference)(Original post by Amirrryy)
they were both "out of phase" right? -

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2naa mate i said STATE the RELATIONSHIP no way the would expect you to calculate that in AS if so they would clarify by saying CALCULATE the phase DIFFERENCE not relationship etc...there was a big discussion about this....it just asks for "in phase" "out of phase"(Original post by RooT_Fifteen)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Oh I see. But nether are in phase & radians are in the specc. Although I'm sure these points have been raised already. We will just have to wait and see then :P(Original post by Amirrryy)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Again, that sounds like you did a really good job at the 6 marker. You clearly have a coherent selection of the ideas that examiners are to look for during marking. 5-6 marks for sure.(Original post by gandanmo2)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Thanks for replying !!! aah really ??? even if i used this experiment instead of the other one ?? again thanks soo much mate !(Original post by iAre Teh Lejend)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Yeah, that should be fine in either case. No problem.(Original post by gandanmo2)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2thanks man ! i also have a few more questions, in the moments question i put Pa (pascals) instead of Nm would i get a mark ?
also for the moments of the back foot i got the right equation but instead of taking away moments clockwise from the anti-clockwise, i divided it as a foolish mistake, but i wrote the right working out, am i likely to still get any marks out of 3 ???
sorry for taking so much of your time ! but thanks much appreciated ! -

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2It's quite clear a lot of cheating is going on. 66% being a grade D is just not justified on reflection of the actual papers, where 70% is sometimes an A grade.(Original post by iAre Teh Lejend)
Dont worry about it. But I've noticed so many people under perform in the ISA, but the boundaries are always really high ? Who are the students that pull the boundaires up ...
... I got 41 in my isa

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2You will get the mark for Pa. You will get 1 mark out of the three for your error.(Original post by gandanmo2)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Very well said, I think AQA need to rethink having modules marked internally, or even sat in class rooms. For my ISA, students were literally sitting right next to each other, on the same bench, centimeters away...(Original post by Liam_W_)

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2No he wont get the mark for Pa 1 pascal (Pa) = 1 Nm^-2 (i.e. force/area for a cable) Pa is not the same as Nm(Original post by iAre Teh Lejend)
You will get the mark for Pa. You will get 1 mark out of the three for your error. -

Re: AQA AS Physics A Unit 2 25/05/12 - PHYA2Very true, I misread Nm for Nm^-2. You will not get the mark. Thank you for spotting my error... but lets hope his examiner misreads that too eh ? haha(Original post by Amirrryy)
