AQA Physics Unit 5: Nuclear and Thermal Physics Discussion w/ Turning Points

I aim for this thread to be used for higher level revision notes for this unit, PHYA5/2B

If you arn't doing turning points and instead doing Astrophysics, Applied or Medical Physics - by all means feel free to post.

Please feel free to post anything to do with the topics involved, from special relativity to Fission !!!!!!!! :biggrin::biggrin::biggrin::biggrin::biggrin::biggrin::biggrin::biggrin::biggrin:

Hows revision going for this ??
Ask questions away :biggrin:
Hi,

I'm confused with the Nuclear radius equation,

R=roA^(1/3)

is ro a constant or the initial radius of an isotope before it decays... in the book it says it's 1.05 fm, in one of the papers it says it is 1.3fm

They will give you the value for r0.

Ro is the radius of a nucleon (neutron or proton).
I can only get the June 2010 past paper and only get the mark scheme for the option does anyone know where I can get more from???
:confused:
Anyone have the specimen paper for nuclear and thermal physics??
