for particle decay equations.
what do you put ^here?
atomic number? mass number? charge?

and what do you put_here
atomic number? mass number? charge?

All i know is that top is A (number of nucleons) and bottom is Z (number of protons)

how many marks do you guys think a B is this year?
2019 was 174 which seems very harsh imo.

I think it'll be a lot less than 2019, 2019 papers are known to be a lot easier

I think this year's paper 2 may be comparable to 2019 in terms of difficulty. However, paper 1 was way way harder this year imo.

An A* would be nice but I only need an A to meet my offer haha. I'll need to do extremely well in paper 3 to get an A* as well

Good luck everyone!

GOOD LUCK last physics ever for some

Ah ok.
but I think I saw beta got +1 or -1 at the bottom. So idk what is actually at the bottom

It depends, relative mass/mass number is at the top and atomic number/charge is on the bottom. It depends whether you're looking at elements or particles. Also, always remember that the numbers on the top and bottom are conserved

Right, thx!

Best of luck to everyone!

Tf was that

That test was not too bad
The area under curve was so mean, the first 6 marker was dodgy but the second medical one was pretty good
I think I have a strong A, we will pray for the A*
But physics is done!
