931.5 is the value on the data sheet
whats the definiton of redshift?
Good luck everyone, thanks for all the help you've given me! Just a quick question, on the grade boundaries it gives marks for an A on each section, what happens if you achieve the overall marks for an A but don't achieve the marks on one of the sections?

it did makes me confused too.

But i just remember it like If it ask about energy released, neutron get into play. But when it asking about binding energy, only care about the nucleus.

I dont know why, But i just do it in this way


Alright thnx i got it first then got cobfused but got it again

I blame my teacher. Its good i realised it now other i would ve lost some avvuracy marks

Yeah there's two versions of the conversion. Ones dated and ones not. I think 931.5 is the most recent? Either way, just use which ever one is on the formula sheet in the exam.
Has anyone by any chance made a list of all the 6 marker topics on the main paper over the past few years? :smile:

They usually allow either! But I'd always check the formula sheet just in case.
Do AQA have a list of definitions somewhere? Some from my CGP revision book aren't right because the mark scheme doesn't allow a mark for it so it would be helpful if someone could provide me with a link please, thanks.
pls someone tell me the definition of redshift and blueshift?
