Are you resitting this unit?

Physics Unit 1: Particles, Quantum Phenomena and Electricity

I'm resitting this exam in summer. There's just under 2 months left now. How's everyones revision going? I have attatched the June 2010 + January 2011 past papers with the marks schemes so everyone can use them for revision purposes. The other past papers can be found on the AQA website. I will also attach the AQA nelson thornes textbook answers. Hope you enjoy and goodluck with revision and especially the exam!! :biggrin:

Technically not resitting since I joined late and wasn't registered for the January exam.
A little bit worried about the first 3 chapters though. Particle physics kinda bug me a bit, while electricity is quite straight forward :biggrin:

Not resitting, didn't fancy doing it in January. I'm feeling okay about the exams. The knowledge is there... my exam technique is pretty ropey though.

When calculating the ratio Charge/Mass of an ion, do you not have to include the mass of the electrons?

Anybody Know how you can tell it is a W+ or W- boson in a feynman diagram? theres 5 diagrams i got and i don't think theres a way you can work it out, unless you memorise it?

Work it out via the conservation of charge for that specific reaction...

So for Beta+ decay:

P --> n + e+ + Ve
B 1 1 0 0
L 0 0 1 1
Q 1 0 1 -1

Obviously between the two sides there is not unbalanced charge. So the weak force must be positive - so that the right side has now a charge of +1 to match the proton's charge.

I'm **** at explaining things - this is just how I remember it...

I'm not even sure if this is the right way to remember it - but it seems to work with all the diagrams we need to know...
