Q7.3 should be 1.31 * 10^22 not 1.32 * 10^22 - Mark scheme says 1.31 as well.
(Helpful and interesting content as always)

If possible would you be able to upload AQA 2018 Paper 2 A Level Physics walkthrough pleaseee? Would be much appreciated ❤

14:08, I swear I'm missing something - where are the mass of the constituents listed in the formula booklet? I know you can get them yourself through dividing the rest energy by 931.5MeV, but it's not the same value used in the video

3.2 asked for period of a semi circle so divide expression by 2

[Johnny-tshh]

19:28 what do you mean by horizontal component to the field?

[becca]

Can anyone please explain 6.3 further for me? I know on the mark scheme it says because K has a lower potential but why would this cause it to accelerate? Same problem for the horizontal component.

I don't get 2.1 why isn't the force

[badyahelamin]

@27:15 question 9: when do we need to change degrees into kelvin in thermal energy or does it never matter what unit of temperature we use?

[grfcdew]

for 32, why dont we consider the 3 free neutrons?

[indianwarlord]

For 10, why can't we use number of molecules = moles x avogadros constant?

[dugsquv]

33:27 why can't we equate work done by field to ke directly

[yashnamodi]

For 5.2) why do we not consider the energy given to the electron neutrino particle?
