Yeah that's what I thought, but I was wondering if anyone had them anywhere else??

Cheers, yeah hopefully someone turns up!!

waaa this is tomorrow! clashes with french which is brill, so i'm sitting for 4 and half hours in isolation woooo

there are no answers to the second set lol

[sasha231496]

has anyone got the january 2012 mark scheme for this paper??? I really need it

[Waqar.]

Anyone got any hints on what questions are definitely going to come up and the common equations used? I know some, just wanna make sure I don't miss any out

You definitely need to know the VUSAT equations;

a = (v - u) / t

v = u + at

v² = u² + 2as

s = (u+v)/2 x t

s = ut + 0.5 x at²

EDIT: All of the above are on the data sheet, but they are nice to know. Make sure you know which are on the data sheet and which are not.

Also some random ones I don't think are on the data sheet;

Force = mass x acceleration

Work done = force x distance

Power = work done per second (Work done / time)

Power = force x velocity

Energy = planck's constant x frequency (mainly used for photons)

de Broglie wave equation: wavelength = Planck's constant / momentum

Frequency of electron phasor = Kinetic energy / Planck's constant

Ahh crap!!

On the mark scheme is says an answer is 1.6x10^17 (1)m (1)e

What does that mean?

[master y]

Someone helpp me! Im so unprepared Can we ask each other questions?

Id say yes but atm im just learning the long answers given in the mark schemes

Interesting. Normally when something is in brackets, it's when something is rounded. As in if the answer was 7.43m, they would write it in the mark scheme as 7.4(3)m. But in your context it seems different. Maybe a mark for units?



Pre-release looks okay.
1st article seems like they'll ask us some random questions, maybe some definitions and a questions using the basic V=IR formula.
3rd article doesn't look too bad, probably get asked about error there as well.

Was wondering if you guys could help me with the second article. And this is probably going to sound stupid. But, what exactly am I plotting to find Planck's constant? I'm assuming frequency goes on the x-axis, but on the y, do I put the Vs values? Or do I place Vs x e, which gives me E, on the y axis?
I know the equation is E=hf, but E is not the same as Vs, right? E is = Vs x e(electron charge), correct?

Thanks.

January 2012 mark scheme:

[Mallett94]

Depending on th question, sometimes E = Q * V (V being voltage)

Basically, our teacher asked us to plot it... the x-axis was frequency (x10^14 or whatever) and the y-axis was E. The gradient of the straight line will be h (Plancks constant). So... yeah your right

We've got this guys... I tried the Jan 11 paper and it's throwed me a bit but I feel like I know all the content so what can I do. Not that knowing the content helps at all with Physics B...
