UNOFFICIAL MARKSCHEME!~AQA GCSE Physics Unit 2 25th Janurary NEW SPEC Watch
So glad they're all over with now, phew!
Friction I guess.
But for the star one I originally thought that we can't live that long but then I realised that just by looking at a star we really can't tell how long it stays stable for and how long it has left.
I personally found the exam to be very easy, so I expect that the grade boundaries will be very high for this exam, especially as there were only 6 questions. I also had time at the end to record the results for all the calculation questions, here's what i got (i don't know the units for all):
3.8 (half life)
25 hertz ?
I got 1.6666666, so it would be 1.67?
