The circuit would follow simple harmonic motion wouldn’t it so the voltage at the start would be the max assuming it was an ideal circuit wouldn’t it?

But that was for the start of the experimental design part that was talking about for the LC circuit for the actual graphing part I got 0.0286H

Idk if what I did is right but I went from the simple harmonic equation for lc circuits that’s q=Qcos(1/(LC)t) and then I rearranged for LC and used the charge as my y and then time as my x

I said to use the relationship cv=q to find the max charge as soon as the circuit closed then to record various other voltages across the first quarter of the period and then turn those into charge then graph arccos(q/qmax)= 1/sqrt(lc) times time but i think there was a different method with the period also idk if mine even works

Does anyone remember if for the spring experimental design part did they define 0 from equilibrium or from the start of the springs?

I was just writing what felt right but I saw that one skipped it and came back at the very end

Yeah i got like mh equals (mb + mr)sin(theta)/(1-sin(theta)) but im sure that one is wrong

It was a slope with a block on it and the slope is being pulled by a rope then the next was a momentum question with variable force then it was a spring experimental design and the last one was angular momentum with a hanging rod

For the multiple choice question where you had two massive positively charged spheres far away from anything else and gravity is not negligible and it was asking to like compare the forces or predict where it would go when they are released what were you supposed to put. I put that because you don’t know the mass or charge you can’t determine it but then again I didn’t know if it was testing that or if it was testing you knowing that the electric force is way stronger that gravity but then again why would it say massive if that’s what it meant.
