# AQA Physics P2. (20th January 2010) watch

1. (Original post by Amandaa05)
I found this paper sooo much harder than that past papers
did anyone else get 3m/s on the last question?
and what is the rate of charge or somethingg?
really want an A* so hopefully boundaries will be low
i got 3m/s literally right at the end of the paper, when id scribbled all over that last page i finally got it. i feel bad for whoever marks it, my writing is crazy.
2. Yup I got the sun for where nuclear fusion naturally occurs...

did anyone get 3m/s for the last question??

AS people or A2 ?
gcse

yup 3 m/s
5. For one of the current calculation questions did anyone get 0.00002 amps? It was the one after the van der graff question

You do know if a examiner can't read the answer then he/she can give you 0 marks right? So it's always good to give directions and write neatly, I got taught to think like for an examiner- like to make their lives a bit more easier cause they mark hundred of papers.
Hopefully by me doing that they're more lenient on me.
7. alright guys what is the actual answer for the first question because i assume it 96N?
8. I think I got 96N....also made the mistake of getting kilohms mixed up with ohms in the formula in the question about the LDR thing...had 0.0005V but changed it to 5V
9. can anybody check for me the first question was definitely 96n and also what scale was the graph we had to draw?
10. Ahh and that question, something to do with kilohoms and volts i think, i got a ridiculous answer (something like 0.0000002) and guessed it would be wrong but even after messing around with it i couldn't get anything better to put that! It was one of the LDR question's i think. Anyone know the actual answer?

I did 0-6 on the Y axis.
12. the answer to that is 0.000002 with 5 zero's after the dot. However please can somebody tell me the answer to the scale on the graph what scale did they do and were roughly the values if anybody can remember.
I did 0-6 on the Y axis.
I didn't like that bit, i'm not very good at the basic thing of choosing scales for axis. I put up to about 30 i think, making sure my line at 20 lux or whatever passed at the voltage we worked out in the previous question (if i remember that correctly).
14. Yeah I got 0.000002 for the one after the van de graph one, and 3m/s for the last one. Rate of charge is current I think. I didnot like the cold fussion one, but I put that they did not publish their results for everyone to see, just told a newspaper... Otherwise I think most of it was ok

I did 5, 10, 15 up the y-axis and then did a line from the top curving down towards the left, is that the right way? I couldn't decide if the voltage increased or decreased :/

why do you think this? please can you tell because the max value went up yo 10v. that was at 10 lux.
17. what did everyone one put for why is this graph a line graph and not a bar graph or something like that.
18. I did scale up to 20 That was the peak Voltage (I got bored so I worked out all the values) and the pattern was a curve going from high to low

Both variables are continuous.
20. Ah I thought something wasn't right I just thought 5,10,15 sounded right! what about the decreasing/increasing? X
