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

Re: AQA Physics Unit 5: Nuclear and Thermal Physics Discussion w/ Turning PointsHi,
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 -
