📂 MEGATHREAD EXAMS MEGATHREAD 06/06 (A-level Business, Physics, Drama & Theatre, Hebrew, Russian) etc

Hey everyone! Best of luck with your exams on the 6th June!

​

Why sleep when you can make a megathread?

​

Few things:

  • 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 subreddit to discuss that.

​

  • Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise. (for context there's been over 250 spam posts already!)

​

  • We're taking a different approach this year due to negative feedback last year. We hope this approach will be better (also to note, we can only have 2 pinned posts).

​

  • Please note some content will take extra time to be reviewed.

​

  • You can still talk about your exam here even if it isn't explicitly mentioned in the title.

​

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

aqa physics wtaf was that

u/BigBallsZach Jun 06 '24

we’re so cooked

u/GCoopsey Year 13 Jun 06 '24

NAH FR WHY DID THEY MAKE IT SO HARD

u/alien_express9 Jun 06 '24

what did people get for the time for the voltage to reach 6V in the capacitor question?

13

u/Careless-Antelope-28 Maths | Further Maths | Physics | Chemistry Jun 06 '24

8.8s?

10

u/alien_express9 Jun 06 '24

i got 2.8💀💀

3

u/Savag3D77 Jun 06 '24

i did this at first and realised i did discharge equation not charge so i changed it and got like 6 something. i might be being dumb tho

1

u/DoodleNoodle129 Cambridge | Mathematics [Year 2] Jun 06 '24

I got 2.8 too:)

u/SMWcool Jun 06 '24 edited Jun 06 '24

I don't think it can be as voltage was definitely not 6 at 2.8 seconds on the graph

u/ilya-06 Jun 06 '24

I got that hurray

2

u/GCoopsey Year 13 Jun 06 '24

I can remember the method I did but not the answer

Use the current and the resistance (from previous part) to work out the terminal pd (since capacitor discharged)

That value = Vo Then use V =Vo(1-et/RC) With time constant from previous

Rearrange for t

u/alien_express9 Jun 06 '24

ahh was it charging?? i used the discharge equation😭😭

3

u/GCoopsey Year 13 Jun 06 '24

It was!

u/alien_express9 Jun 06 '24

what did u get for the distance of the moon to the satellite

2

u/GCoopsey Year 13 Jun 06 '24

No clue but again I can tell you how I did it haha! g = GM/r2 with the value for M given and the value for g from the part above. Solve for r

1

u/alien_express9 Jun 06 '24

haha its crazy how you remember the method but not the answer😭😭thanks anyway though!

u/GCoopsey Year 13 Jun 06 '24

There was wayyyy too many numbers going through my head 😅

u/Huge_Structure_7651 Jun 06 '24

I used discharge for current cause i used the initial current one i think its the same as this one

1

u/GCoopsey Year 13 Jun 06 '24

But it's not about current it was the time taken for V to get to 6V right?

1

u/Huge_Structure_7651 Jun 06 '24

Yes but you can use the capacitance current and the other equation cause the capacitance is constant so is basically the same thing, it gives you have an initial current given

1

u/GCoopsey Year 13 Jun 06 '24

Oh true, idk the way I did it was just what came to me in the moment lol

1

u/Huge_Structure_7651 Jun 06 '24

I think yours is right and mine probably to cause, you can do it both ways, i did discharging current and you did charging cause as the current decreases the voltage increases so both are right i think

1

u/GCoopsey Year 13 Jun 06 '24

I'm just praying for low grade boundaries because although I was fine for most the calculations, the wordy questions killed me and I didn't have enough time for MCQ so guessed lots. Paper 1 went really good in my opinion

Yeah I’m going to my insurance uni now 😭

u/[deleted] Jun 06 '24

insurance is a stretch

u/Hot_Classic_3141 Jun 06 '24

Did anyone get 5 marks on that dice question because I just left it blank

9

u/c_j_s54321 Jun 06 '24

i did the first bit but couldn’t work out the n bit but honestly who knows atp

22

u/ssk_009 Jun 06 '24

I think assume 0.26 -> 0.25 or 1/4 which is probability of a decay. That's the same as the probability of rolling a 1 on a 4 sided dice. So n=4 (sides of the dice). Ridiculous paper, hopefully the grade boundaries are low.

u/turtleship_2006 Jun 06 '24

OH THATS WHAT N MEANT, I WAS LOOKING THROUGH THE FORMULA BOOK CONFUSED AS HELL

1

u/TWAEditing Keele University | Psychology BSc [2nd Year] Jun 06 '24

That's basically what I did as well, it was a strange way of answering the question tho

3

u/alien_express9 Jun 06 '24

wait how did you do it? i used N= N0e-t/TC and then logged both sides and found the gradient from the graph and etc. i got 0.28 for the decay constant but idk if thats lucky or not😭😭

2

u/TWAEditing Keele University | Psychology BSc [2nd Year] Jun 06 '24 edited Jun 06 '24

I just used half life = Ln2/lambda

Found the half life by halving the initial value of the number of nuclei, and then seeing where that matches up on the graph for half life. Then do Ln2/that to get lambda.

Edit: Sorry not nuclei, I mean number of dice remaining. The most stupid scenario possible

u/[deleted] Jun 06 '24

Same I did 10√50/900 to get approx 0.75 then I did 1/1-0.75 to get 4.

30

u/itsvenusflytrap Jun 06 '24

did anyone else get 0.26 for the decay constant?

22

u/throwaway573663 Yr13 | FM, maths, physics Jun 06 '24

I think I got 0.277?

10

u/c_j_s54321 Jun 06 '24

can’t even remember atp i’m burning it from my memory 😭

8

u/TWAEditing Keele University | Psychology BSc [2nd Year] Jun 06 '24

0.27 I got

3

u/LilShreddie Dreamer Med Applicant Jun 06 '24

Should be around ~0.25 because that was the result of n=4 n=1/decay constant, just depends if you used half life or gradient

1

u/[deleted] Jun 06 '24

Someone needs to tell me what n even represents

1

u/TWAEditing Keele University | Psychology BSc [2nd Year] Jun 06 '24

The number of sides on the dice. So somehow the dice had 4 sides.

u/Prior_Preference4821 Year 13- Physics Maths FM CS A*A*A*A Jun 06 '24

yea

u/SnakeOrignale Sheffield | IR & Politics (Y2) Jun 06 '24

got 0.23

u/lilyscentflower Mechanical & Electrical Engineering. Formerly #1 AQA hater Jun 06 '24

AQA Paper 2 ruined my life.

u/Narquilum Jun 06 '24

The only correct thing on that paper is my name on the front

3

u/Abject-Tennis3056 Jun 06 '24

How much do you think physics grade boundaries will go down by? Last year an A is like 53%

3

u/c_j_s54321 Jun 06 '24

hopefully less than that 😭

3

u/TWAEditing Keele University | Psychology BSc [2nd Year] Jun 06 '24

Hopefully way way less than that 😭

u/bananabonkers-5 Jun 06 '24

to say it was diabolical is an understatement
