Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEthink it was true false true true? any other?(Original post by JLR96)
for the true or false question it was definately: false for the second, true for the third and fourth. not sure about the first -

Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEdid we have to link all 3 of the left hand boxes with the right hand boxes? I have a feeling i only linked the 'average' one for some reason?(Original post by JLR96)
for the one with average speed and instantaneous speed, the other was for velocity -
Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEhi its for the old spec p4 p5 p6 not sure if its A or b think A..(Original post by melv97)
hi everyone- is this thread for ocr a or ocr b?! i did this (a) one today and i dont recognise the questions
but i think it went okay
max:P -
Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEIm not sure? people saying we only had to link one...?(Original post by physicshelpme)
did we have to link all 3 of the left hand boxes with the right hand boxes? I have a feeling i only linked the 'average' one for some reason? -
Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEone of my friends said that it said to only do one, but i didnt realise and did all 3?(Original post by physicshelpme)

Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEits A(Original post by Smko)

Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEit was somthing to do with the hoops the other one(Original post by JLR96)
for the interaction pairs, it was:
the weight of the gymnast and the pull of the gymnast on the earth
& something else
I THINK -
Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEYeah, I'm that friend.(Original post by JLR96)
one of my friends said that it said to only do one, but i didnt realise and did all 3?
It did say draw one line, from the correct reason to the correct explanation.
What did you lot put down for the question to do with KwH and an hour costing 20p??? -
Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEThey repel each other because same charges repel each other, so as both are identical they get the same charge, and so they repel each other.(Original post by ollielawn)
what about the question with the rods?
Right, or am I missing something? -
Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEME
yeh that's right,:confused but I mean did they gain a negative charge or positive, because I thought that the cloth 'brushed' the electrons of the rod giving the rod a positive charge and because they both have the same charge they repel. Did I get that wrong?

Re: P4 P5 P6 JUNE 2012 OCR 21c PHYSICS UNOFFICAL MARKSCHEMEIm not sure, didn't think about that i just wrote negative straight away for a reason I can't remember. You will get a chunk of the marks for saying that they repel each other due to them having the same charge though.(Original post by ollielawn)
