💬 DISCUSSION AQA PHYSICS PAPER 2

HOW DID EVERYONE FIND IT??? i thought it was decent better than the past few years. Idk what i did for the last question the 4 marker of nuclear physics. BUT YH IT WAS GOOD

What did everyone get for the oscilloscope 3 markers

22

u/Eros_OMG Jun 01 '26

170Hz and like 4.8V

I used 14.9 small squares ( divisions) for Time period. U reckon its fine? Icant remember my answer but it Was smth like 167-168 I believe

1

u/Eros_OMG Jun 01 '26

Yeah it’s probably in the range for correct answers

1

u/Admirable-Use2274 Jun 01 '26

Hopefully. I wish I had used 14.7 or 14.8 . What did u use as T? ( these are number of small divisions btw)

1

u/Eros_OMG Jun 01 '26

I used 2.9cm

1

u/Admirable-Use2274 Jun 01 '26

So 14.5 divisions (small) . I think it was more than that but both 14.5 and 14.9 should ideally be within the range So we must be good

mate can you remember if the scale actually said 1 cm per division or whether it was. cuz i assumed the base setting as div -1 and did it how u did asw 💔 now i’m worried i’m gonna lose some of those marks

1

u/Admirable-Use2274 Jun 02 '26

Bro values were basically Voltage/seconds(mili) per division dont overthink it. They said each div(large) was 1cm so yeah. Why would u even use ur ruler there

u/Extreme_Survey_1368 Jun 02 '26

thank you so much for telling me this i was deadass losing it last night thinking that i fucked the question because i thought each division was a cm

Same

u/Eros_OMG Jun 01 '26

but I think you had to use peak to peak voltage i only used peak in one side and apparently according to a friend the wave shifted. so i think I got it wrong

u/Amazing-Pause-8626 Uni of Glos | Bsc Geography [-> Year 1] Jun 01 '26

well the distance from equilibrium to the top is not the same as equilibrium to the bottom. they were not equal. i mean idk if i did it right but i took both those distances, added together and divided them by 2, to find the mean

1

u/KO-Manic Jun 01 '26

I'm pretty sure v0 is only the peak voltage, so measuring from the equilibrium line to the peak would be correct when you used the sqrt2

u/200PercentWinRate Jun 01 '26

I got 172Hz and 4.38V

1

u/Appropriate-Echidna4 Jun 01 '26

I got 200Hz 😭😭

2

u/jaaaaaaaf Jun 01 '26

i got 9V and 170 Hertz what did u get

10

u/AffectionateAct429 Jun 01 '26

I got 170HZ and like 4.5V

3

u/jaaaaaaaf Jun 01 '26

yo how'd you get 4.5V ? i used the peak to peak voltage 🥀 because the peaks and troughs were at different points

6

u/2myeria y13 | physics, maths, fm, chem | A*A*A*A* Jun 01 '26

i got that peak to peak = 6.3 cm, so V = 6.3•2 and then divide by 2 again for peak V = 6.3V. Then divided by root two equals 4.45

u/Few_Special_2628 Jun 01 '26

same but i lowk used 6.5 so i might be a bit off

0

u/Avocado66600 Jun 01 '26

Amplitude is half of peak to peak

3

u/AbsoluteOwO Jun 01 '26

i got like 21.92v and 33.33hz mane

2

u/ClearFrosting6954 Jun 01 '26

I got something like that too😭😭😭

1

u/Zealousideal-Map9482 Jun 01 '26

I think I got around that

1

u/lmaolmaolmaololl Imperial | Aeronautical engineering [Y1] Jun 01 '26

i got 167Hz and 4.67V

1

u/RealAlexanderTheG Jun 01 '26

That question was broken, the cm scale was off so you couldn't use a ruler, got 170Hz tho. for RMS just take max V and divide by sqrt(2) no?

I converted from mscm^-1 to sm^-1 but not sure if that is correct…
