How was that for everyone? I felt it was okayish but could have been better… I was convinced radiation wouldn’t be in the exam, that 5 marker was so hard for me :frown:

which 5 marker are you on about?

How did u work it out pls

So you work out the elastic potential energy. Then since it is maximum velocity, that when all the energy has been transferred to kinetic store so you do root(2xEnergy all divided by the mass)
the elastic potential energy was 0.36J and the mass was 0.02kg I believe

what did everyone put on the becquerels one i wrote about half life and nuclei decay i think i got D was the most unstable and B was the most stable not sure about the others

it was one of the required practicals i think what did you put?

Ohh. We never covered it due to Covid then my physics teacher going on maternity. I put for the power output that it would go through all the resistors the power output would increase due to the equation P = I^2R

Why on Earth did they put circuits in???

frr it was literally in the "not assessed" list
