Re: Edexcel Physics Unit 2 25th May 2012I have mix feeling, some questions I never came up but using my knowledge I wrote the answers down. I am not sure what would be the outcome, overall I would say it was hard(Original post by AS01)
oh I did unit 2 only. the paper for unit 2 was not that hard. it was just the last question that was tricky. how did you find it?

Re: Edexcel Physics Unit 2 25th May 2012the question on doppler effect and ultrasound was different. what did you keep for them?(Original post by UserInvalid)

Re: Edexcel Physics Unit 2 25th May 2012I will write brief in points :(Original post by AS01)
the question on doppler effect and ultrasound was different. what did you keep for them?
- Pulse is emmitted and reflected pulse is detected
- When the pulse passes through different tissue, there is significant change in the ammount of energy relfected
- So there is difference in emiited and relfected. Hence thats how it works lol -

Re: Edexcel Physics Unit 2 25th May 2012I think its right! I wrote quite same as urs. I looked up in the book and it said something about change in speed as it moves from one medium to another. don't know how it related to forming image.(Original post by UserInvalid)

Re: Edexcel Physics Unit 2 25th May 2012I hope the grade boundaries go low.(Original post by AS01)
agree!
A girl sitting next to me was doing the exam, I think she suffered. She ripped off the last page of the paper which contained formulas in the exam hall lol. -

Re: Edexcel Physics Unit 2 25th May 2012hope the same that will increase chance of getting nice UMS point.(Original post by UserInvalid)

lol!! SHE RIPPED OFF THE PAPER !!!
I think she was like I can't take it more! -

Re: Edexcel Physics Unit 2 25th May 2012I think its gonna be around 55 but not even close to 60.(Original post by UserInvalid)
dunno it would be hard for the examiners to differentiate for A and B grades, as all people who did the exam suffered.
It can go about 52-55 or maybe low wbu?

1. c
2. b
3. c
4. d

Re: Edexcel Physics Unit 2 25th May 2012Good to hear...
For question 5, the resistor obeys Ohm's law which means resistance is constant. Using "P= (V^2)/R", where R is constant, as P is increased V also increases but less as it is squared in the formula. Hope that makes sense. -

Re: Edexcel Physics Unit 2 25th May 2012yeah it does, thanks, i was 50/50 between A and D, but according to his answers i got 9/10 which is still good.(Original post by m.usmani)

Re: Edexcel Physics Unit 2 25th May 2012I thought the paper was okay aside from the final question, which I messed up on because I added the voltages, meaning I'll have lost out on the majority of the marks. (Though I did get the "show that the terminal voltage was 12V" one)
