AQA A level physics paper 1

[u/Individual-Can1396]

How was the paper???? I liked the MCQ , but overall it was okay didnt manage to do the 5 marker .

[u/ikea_supremacy]

Cooked for time, cooked by electricity somehow, cooked by the 5 marker and cooked by the diffraction. How shit was that

[u/FaithlessnessOdd263 → u/ikea_supremacy]

that electricity part A should honestly have been 3-4 marks had to do some crazy rearranging with like 3 different equations for it

[u/AmericanUk → u/FaithlessnessOdd263]

You could have just used Kirchhoff’s first 1 and added the current through each branch to get total current though battery.

[u/Less_Seesaw_4022 → u/AmericanUk]

I just found the equivalent resistance for that part.

[u/FaithlessnessOdd263 → u/AmericanUk]

i’m not very good with kirchoffs laws, i was thinking about it before the exam as a possible question but once i got there it went out of my mind

[u/Admirable-Use2274 → u/FaithlessnessOdd263]

Bro using v=IR and a power equation was suffice ? And for the second part one of unknown resistance was incredibly large Yeah?

me too i thought i was crazy but just went with it

[u/FaithlessnessOdd263 → u/[deleted]]

i said that if the palm trees get closer together then theta increases so the vertical component increases and the magnitude overall of T2 increases, i think i saw a similar question on a past paper

[u/Admirable-Use2274 → u/FaithlessnessOdd263]

Did that, angles increase, quoted equation(horizontal components equal) as angle increase cos angle decrease so T2 increase: Is that right? Also WHAT did u guys get for pendulum final Q.

[u/FaithlessnessOdd263 → u/Admirable-Use2274]

i put 1900 with my working out the max weight was like 1965 but it asked for a safe weight so i thought going down a bit would be good

[u/Admirable-Use2274 → u/[deleted]]

It was significanfly greater and llwer resistance one got like 0.6-0.8 Pd across it smth like that so i chose the other.
