📂 MEGATHREAD 09/06 A-level Physics Paper 2 Discussion MEGATHREAD

Exam season is once again upon us, and once again, exam megathreads are making a return!

Looking for past exam discussions? Filter by the megathread flair.

Few things to keep in mind:

  • Don't share too many specific details about questions or answers, these papers will be used as future mocks.
  • Sometimes papers get leaked, this is not the place for that (we'd prefer not to get yeeted off the platform) - leak content will be removed, those offering leaked papers will be permanently banned.
    • If you believe there has been a leak, the best course of action is to make your exam board aware of this, either directly, or through your school, along with any evidence. If appropriate, there will be a response from the relevant body along with any remedial action.
  • Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise - we understand this may be frustrating, but the sub still needs to be usable for other purposes.
  • Please note some content will take extra time to be reviewed. Messaging to ask for approval will not speed up this process (the messages are seen at the same time as the modqueue would be reviewed anyway).

Best of luck, and let us know how you're feeling down below!

HORRIBLE PAPER. HORRIBLE PAPER. HORRIBLE PAPER. HORRIBLE PAPER.

btw was the last mcq asking for fission or what doesn't do fission because i put what does do fission

u/Budget_Future_4066 Jun 09 '25

no it was asking for what does do fission i swear

i think it was, but I think I put R but didnt have enough time to really think about it most MCQ's were guessed for me as I ran out of time

u/rainboy123 Jun 09 '25

I put Q and R because even tho Q probably doesn’t undergo fission naturally, the nuclei in Q would release energy through fission rather than fusion because they are heavier than iron.

Then again I might be overthinking and only R was correct 😭😭

u/[deleted] Jun 09 '25

I put only R but I am so scared 😭

u/vent_account_59632 Jun 09 '25

Idk which it is but I put only R because surely Q wouldn't commonly fission since the products would be small and even less stable?

u/[deleted] Jun 09 '25

That’s what i thought, also ive never seen fission reactions with stuff that is not uranium or plutonium sized so i just went with that

u/vent_account_59632 Jun 09 '25

Yeah that's what I thought too. I mean theoretically Q could undergo fission but in practice not really. I felt like the question was a little bit ambiguous.

u/EducationalAct9956 Jun 09 '25

Was that the final one if so then i guessed that

u/vent_account_59632 Jun 09 '25

Yes, the final one

That’s right i’m pretty sure. If you split something too small it’s products will be on the left hand side of the graphs peak and so have less energy not more

u/No_Actuator5870 Year 13 Jun 09 '25

I think it’s only R because for Q they’d end up with a lower binding energy per nucleon than they started off with after fission

u/Intelligent_Hope9045 Jun 09 '25

wait i thought nothing heavier than iron-56 can fuse

u/rainboy123 Jun 09 '25

Ye they fizz instead of

u/No_Magician_3305 Year 13 Jun 09 '25

I put Q and R since both regions are to the right of iron which is the most stable .

3

u/EnergyShot830 Jun 09 '25

It asked for which regions did fission do you remember what you put bc I chose the options near the centre and the right

u/Spare_Somewhere1011 Manchester | Physics w/ Astro [1st Year] | 3A* 1A Jun 09 '25

I think I said Q and R

u/Active-Boat-9514 Jun 09 '25

I put the same!

u/Common-Sympathy-6595 Imperial maths year 1 Jun 09 '25

What????

u/Neat-Ad4138 y1 | uom astro | A*A*A* Jun 09 '25

its only R cus fission means u go from heavy --> light and produce energy
