how did everyone get 1.3 A for the second last one. I got 0.67 A because when the current comes at the junction 1/3 goes to where there is more resistance and 2/3 where there is less resistance cause current always goes to where there is less resistance. Also the top bit of the parallel and the bottom bit were in the ratio 2:1.
Yes so 2/3 =2/3 2/3 x 2 = 4/3 4/4=1.33.. I just put down 1.3 (2.s.f)
plan now is to work hard this half term fo unit 2, retake unit 1 in jan. problem is i might end up getting b/c in physics and uni will require an A which i know ill get by the end of A2 but they obviously wont give me an offer
Ill post it again because i urgently need to know.
On the page with the question about the feynman diagram i think i didn't see the question about naming the interaction. was there any other questions on that page?

the question about naming the interaction was on the left hand page. the feynman diagram was on the right hand one with no other questions... i highly doubt you could have missed the whole of the left hand page

Can you give me some other examples please as i think i may have done without realising? Unless that was the question where i wrote weak interaction instead of electron capture? Thank you.
At least i can resit it next year if i get a U then
Wel, to be honest, I found that so so so many people found the last question on electricity hard, tha the examiners will see this and make it so the UMS marks higher - so even if you got the question right, everyone gets shifter up a little (hopefully - just spectualting). I.e. Grade boundries are lower.

It was alpha decay, electron capture, where did the electron come from etc.
Um, I think I got four volts? (Eight divisions, each one 0.5V...)
i put 2V because surely it is just where the top of that line was from the 'zero' line because that is where all the beaks would be? top to bottom would surely be 4V but measuring peak to trough? :/ i'm probably wrong though!
oh **** did they ask for peak to peak or peak voltage?
i thought they asked for peak and i wrote 2v, then used that for rms on the next page
FUUUUUUUUUUUUUUU
You'll probably get carry on marks though I think?
I'm hoping that the A boundary is about 50/70 then I think I might just scrape an A
peak to peak voltage was 4v rms value was 2/root 2 which is root 2 it was electron capture
and on the page with the beta decay i put the top one A-4 and Z-2 (can't remember which way around the A and Z goes lol) The new proton number was 18 which is that of Argon.
