Edexcel A Level Physics Paper 1: Advanced Physics I 9PH0 01 - 26 May 2022 [Exam Chat]

Damn i got 0.2. Where did u have to draw the tangent

That diode question 😭

What did you guys get for the energy level in eV for the particles question on spectrums

How was the tennis ball question for you guys? I was stressing for a while but I think I’ve gotten it or at least most of the marks.

bro that was so hard

I used the equation for centripetal force and weight of the ball to set up a simultaneous equation with socatoa, something like Centripetal force x cos(theta) = weight. Then the masses cancel out so you don’t need that and you should just get the cos(theta) = g divided by V^2/r. From there I just used inverse cos to get theta. Anyone did a similar thing to me?

measured angle was 53 and calculated one was 51 right?

What did you all say about the LINAC one??? I can’t see how it was a 6 mark question. I only made 3 points (1. Alternating pd/E field, 2. Velocity increasing with fixed frequency 3. Drift tube length increasing). What is the rest!!??

I failed this exam. I will need paper 2 and 3 go save me. Or hope I get enough marks from calculations and e.c.f
All these answers given are stressing me out!

What did u do for the capacitance question I was so confused

I was a bit confused as well but I just picked 2 points on the graph and then used the exponential equations and rearranged for RC. Not sure how else you would do it tho, I had no clue what to put for part A tho.
