yup i also got thatFor me yes it was corroded because the distance was 1.5cm instead of 4cm... let's hope I got that right at least

It was mostly easy for me except for the last question where I assumed that when one bulb was removed, the place where it was removed is still connected so I made the current in parallel and my argument was that in parallel resistance is less so each bulb gets enough current to operate whereas when each one is connected alone in series the resistance is more so they don't get enough to operate, which I think is the wrong answer but still a valid argument isn't it? They didn't specify that when a bulb is removed whether or not the connecting leads are connected back again or left separated so that's what caught me out... but other than that it was pretty alright!
i chose superposition but apparently I got everything wrongbtw last multiple choice i choosed polarization although some said super-position not sure
thank God! It better be that this time around too!woaaah there the highest it ever been was 56 for unit 2 its usually pretty low
serieswas the circuit in series or in parallel?
the current for both lamps was different and in a series circuit the current is the same, one was 0.17A and the other lamp was 0.2A so i think the circuit is in parallal, well thats what i didseries

Hey..i checked for june 2012 grade boundaries unit 2 they're 66 for every exam.i dont get it? How are u people saying tht its gonna be 54-60 for an A??ya im thinking 59-61

the best question was the 5 mark graph question who agrees??
JazakAllah. and what about the total As and A2 marks?? For an A grade?

Wht is the difference between ums and raw? i dnt know anything about it.u need to get 480/600 in all 6 modules UMS not raw
Wht is the difference between ums and raw? i dnt know anything about it.
I didnt get the last part."u need different amount of raw marks each year ...." ??? U mean after reappearing.i dont get it.ums is the grade u get out of 120
raw is the mark on the paper out of 80
to get 96 ums marks aka A
u need different amount of raw marks each year which varies according to student preformance
Nope it doesn't. Sorry
Are you actually retarded? Just accept the correct physics.
When the length was doubled and the cross sectional are was doubled okay. If the length is doubled there is twice the amount of charge carriers! Therefore I=nAvQ compared to new I=2n2AvQ therefore v is V/4
