or will paper 4's high threshold be an issue :/. if it turns out to be higher than 60 ..
nopey'all
i'm a P2 student and i'm flipping out looking at all you P4 kids
Is there anyone who got their hands on the Feb March 2018 series papers?
because the decay constant is big so unstable
dint v have to compare?
yh but i wrote abt half life and decay constant but dint write the equation
since lambda is large, t half is small.. so the time taken for the number of undecayed nuclei to fall to half its original value is very small.. hence , the nuclei wont stay in the sample for a long time
ohhhh
well i am praying as well that it isnt that high.. but i have just HEARD people saying that it was very easy..
you should have mentioned building 2d image as well first
mention x ray
people who say its easy often make silly mistakes
well in some mark schemes there was one for the fact that the image can be rotated
well it was when large unstable nuclei emit radiations like alpha beta and gamaa to produce stable daughter nuclei
