# EDEXCEL PHYSICS UNIT 6 &gt; HOW WAS IT? watch

1. (Original post by DmAsTeR)
that paper had some dodgy questions... i did some of them really good...some i had no idea, my mind went blank..
Same here! I'm kicking myself for not learning the photoelectric thing!
2. (Original post by DmAsTeR)
the next one after...i hope it was less..cos theres heat loss...i put a bit more detail but...neway...what was it??? its less yeah!?
yup ...... i put less but i have no idea whether its rite or not
3. (Original post by riks2004)
temp change was 3.62K or degrees C didnt matter which 1 cos 1 degree C = 1 K but i put K cos the specific heat capacity had k in.
I got a value with a 10 to a -ve power !
4. btw im quite sure it was 47 kilo ohms?????? but does any1 knw 4 sure????
5. (Original post by prospector60)
yep except it was 47 kilo ohms
thats what i wrote.. 47K
6. (Original post by roochis)
thats what i wrote.. 47K
ignore me... i was looking at the 'kilo' bit.. you meant 47 instead of 72?
7. Anyhoo peeps... i'm off to cram as much chemistry i could possibly get into my brain!

I'm sure we've all done fine..

Try not to think abuot the exam too much cause we tend to look at the bad things.... and not all the things we got right!!

Ciao!

Omg!! I didn't see the "Kilo" part on the paper!!!!
9. For the photo electric one i drew the circuit diagram with a variable resistor etc

there was definitely a a resistor with kilo in it...u'll still get marks for method though

My diagram was correct except for the cell. I forgot to put a cell in the circuit and there should be one
12. wooohooo that was quite a lucky exam for me. I got the same answers!!! i hope your right lol. Number of electrons 8exp7, temp increase 3.6K, p.d across 25ohm resistor 0.797mV (might have been .979 cant remember) 1.4exp7 recession velocity, remember getting mass of electrons exp-28or29, greater than electron at rest , did anyone else get something similar please?
13. that paper was stupid...nothin on accelerators

me too...

Thanks for trying to cheer me up. But I feel like a total looser!!! Tomorrow's Chem unit 6 is gonna be even harder!
16. oh yeh the recessional velocity is towards the earth...u must put that...cos it was a blue shift
17. What is the source of centripetal force for the electrn in the bubble chamber?

I think i got exactly the same.. apart from the resistor one.. cause i can't remember it for the life of me.. although the 0.79mV looks familiar!
19. good luck with chem guys, im glad i dont do it, some of my friends got 4 exams tomorrow!!

wooo.. i put that.. cause i was wondering where they were going to get 4 marks from!
