Re: PH1 17 may 2012Ah, lucky(Original post by Emissionspectra)
I found it all right. I think i messed up a little bit but overall nowhere near as bad as I thought it was going to be!
Did you get the value for D in the end? -

Re: PH1 17 may 2012I thought it went pretty well! I messed up the equation in the decay of K-, mind went blank! I just wrote proton in haste even though I knew it was wrong.
For the electron capture I put the antineutrino rather than the normal neutrino. Oh and that 6 marker on AC?! I didn't really know what it wanted me to write, the top half of my answer was some made up stuff but I think I got some of the points in the bottom half.
Surprisingly, no resistivity came up, didn't even come up in January. -

For D I think I got 0.23 metres squared but dunno if that's right. My resistive force was 505N
D4rth I think you're talking about a different exam
I think this is for the WJEC exam
I was wondering why everyone was talking about D, "wjec" doesn't come up in the thread title. -

Re: PH1 17 may 2012I think i got the same, i know i got a resitive force of 505N(Original post by D4rth)

Re: PH1 17 may 2012I'm sure I got most of the spring constant question wrong, I used the wrong equations etc
For the table in the first question on circuits, would the charge have gone through Buzzer P even if the switch was on? My last six values were all 'on'. It looked wrong but I didn't change it :/ -

Re: PH1 17 may 2012Ye I got that, what did you get for the Current when the spanner was dropped in between the terminals?(Original post by hornet_56)
8.4C?! Which question are you talking about?
One of my charges was was 17000 or something but the current was 120A!
You talking about the right exam? lol -

Re: PH1 17 may 2012I got something like 0.07 after I divided something. but then I realised I should multiply, and got thousands of amps instead(Original post by Emissionspectra)

Re: PH1 17 may 2012I said infinite/ very very high.(Original post by cleverslacker)

Re: PH1 17 may 2012ughh i got 0.03 but then i changed it to 0.1(Original post by cleverslacker)
I think you had to divide current (120A) by Ir (0.03)

Re: PH1 17 may 2012Arrgh, Hated it. Overall I have to admit the paper wasn't as bad as a comparison to the past papers. Guys I is so important that you sleep well the night before and have breakfast before going on. I got to experience it.
