Seeing as we're likely to get the replacement paper, will trying to predict what will come up on this exam by disregarding what came up on last year's work?

what do you mean by replacement paper?

Usually two papers are written for each unit each year just in case there is a leak or something.

Apparently a van containing AQA exams was stolen so we will most likely get the other one they writ.

Nope don't think so.. Just checked news now and AQA is saying Physics papers will be unaffected.

June 14 paper, calculating mass lost on 1biii) why do you multiply binding energy by 1.6x10^-1? Where did they get that number from?

can someone tell me how to convert from U to kg and to MeV ect and any other ones we need to know, always forget how to convert between these! cheers!

1u = 1.661*10-27
1u= 931.5MeV

Just started reading the book on the optional unit. If I pass this, it has to be some kind of record. Passing A2 physics in 2 days

This is on the data sheet so no need to worry!

Ratio of 2:1

energy released is Mev*1.60*10-19*1.0*10^6 because mega electron volts

191*1.60*10-19*1.0*10^6= 3.06*10-11
E=mc^2
m=E/c^2
m= 3.06*10-11/ (3.0*10^8)^2
= 3.4*10^-28

is that alright?

Ah yeah makes sense now thanks :smile:
