Edexcel IGCSE May 15th Physics 2014 [OFFICIAL]

Post in here if you want to discuss the exam or you want to share anything!!

Hi, I actually found the paper ok but it was harder than I expected. I think I lost around 10 marks. One question which I did find difficult was the one on using a detector to investigate how much uranium was in the graphite rock.
What did you guys put for it?? I said something like use a Geiger-muller tube to detect radiation, then, you can use the knowledge of uranium's half life to deduce how old the rock is.

Thanks
