Naw, I'm sure they won't. In decay questions they just give you the mass number and atomic number of the element, and probably a alpha particle given off next to it or something ( which is 2 protons 2 neutrons, right? )

Wasn't the decay stuff P1? It seems so long ago.

I think it's P2 or P3. There's stuff on radioactive decay there.

No, the decay was in P1b, but there was electromagnetic waves (gamma) P2. There is nothing in P3.

Is it enough if it says explain difference between virtual image/real image or what is a virtual/real image to simply say:
virtual cant be projected onto a screen.
real can be projected onto a screen.
?

Yes, but you may have to explain you get an image because light passes through to the screen.

In my revision book I'm sure that there was a little bit on alpha particles. Maybe it's part of the nuclear power reaction chamber section, but whatever

2 more questions!

1. why is the core made of iron? increase magnetism?
2. why is insulated wire and not insulated wire used to make the coils?

xxxxxxx Good Luck Everyone! xxx

I think in these AQA exams luck is important, if you remember we had no titarations in C3, so we may have an hard paper, or we may have a great paper missing all the hard bits. I don't know which one I want though!
