I hav some quests in ppr may june 2002
 2c)
8c)
and in may june 2007
2a) and 9a)
and i need explanation i hav the markin scheme but i need to understnad it
thnk u 

2c: the change in speed is 9.5 m/s cause frm 9.5,when the ball touches the grnd it comes to 0 so its 9.5 i hope thats what the mark scheme says

8c: the function of a diode is that its a rectified, it changes frm A.C to D.C so as the A.C current flows in forward bias of the diode, the diode allows the flow but when A.C flows in the opposite direction, the diode doesn't allow that so A.C changes to D.C

n for 2007 i don't hav the paper so if u give me the question, ill clear it

all the best

Thanks but sry to burst ur bubble but the answer in the markin scheme is 1.5 n 17.5 m/s  
n sry i neede to ask 9c) not 8c)
n neva mind for 2007 they r all daigrams
Thanks alot aneways

which paper?

I m sure he meant physics paper 3

[astarmathsandphysics]

but which paper? Post the paper number too

[247sports]

can any1 plz explain deflection of radiations in magnetic fields???  and any easy way to remember them

see usually they need u to answer whether it deflectin into or out of teh page
so for alpha its ALWAYS out  of THE PAGE wherreas beta is always into THE PAGE
PLZZ CORRECT ME IF I AM WRONG
n always mwntion the wrd curvd if the radiation is in bettween a magnetic field

Salaam ppl! Hope the Bizness paper was gud for all whu tk it. Ok...I've got like a problem. I didn't exactly study Physics much in recent days. I'm not exactly so sure how to prepare for tomorrow. I studied all the relevant stuff from Complete Physics by Stephen Doyle before the mocks . Alhamdulillah, I did reallly well in the mocks. I've solved pastpapers too like upto 2001 maybe. But all this was before the mocks mainly. I only revised a few physics chapters in the study break. Now, my problem is what do I do!!! Should I revise the complete Physics book again. The thing is they dunt really cover everything on our syllabus to the word, like these experiments and stuff. I'm scared I wont finish today on top of that. Or should I just go through the checklist from the cambridgestudents website. I'm sorta confused and getting a bit nervous .....Please offer sum advice.PLease helpp.....Thanks!
