View attachment 41333 what am i doing wrong, legit was more prepared for trials.

wait what the actual f, that’s enough physics… 60 + 40 is 100°, shit

is it meant to be cos 30

yeah i gathered that, whoops

How do you know what angle to use for
-Torque (in B field and normal troque)
-Flux
-Magnetic force

I think the angle for torque is the angle at which the force is applied. like the angle between the force vector and the surface
Flux is BAcostheta and the angle is between the perpendicular to the area and the direction of the magnetic field (this might be wrong)

-Magnetic force

Torque normal (angle between the force and the pivot point)
Flux, torque in b-field (angle between the b field and area vector)
magnetic force (if this is bilsintheta thingy then angle between the wire and the b-field)

they way I like to think about it is by rotating the given angle to zero, and then figuring out if subbing in theta=0 provides an accurate result to what I know and then working from there. it’s definitely a weird method but more reliable than memorising each one or trying to visualise it other ways

i just break it down into the max component side and find the length of that side using trig. then sub into formula normally

Gluons mediate the strong force. Photons mediate the electromagnetic force. EM waves interact through the electromagnetic force because they are themselves oscillating electric and magnetic fields perpendiclar to each other.

I think of gluons as like nuclear glue

long time lurker here, just wanna say good luck to everyone <3

 

[Hudz777]

good luck everyone, hopefully no one makes any silly mistakes like I did earlier !!
hopefully the test is filled with rlly hard calculations and no writing xx
( yes i know i got q5 math mc wrong but i promise i can do hard math )

FR I didn't study the history stuff enough :/

haven’t really even looked at it. will go over it in the morning… a quick glance is enough to bs something in the exam if i have to
i planned to do so much physics study but ended up doing like 2 days.

 

[BananaFingers]

yeah same ig

but arent 9 marker written responses easier to bs than doing hard calculations

Rlly depends on how messed up marking criteria is

no. theres no such thing as bs. everything you say needs to have purpose and meaning. you really need to know your theory well and use terminology correctly and where its relevant. if the marker doesnt see those buzzwords, youre not getting the marks. also you need to include calculations and formulas in the 9 markers depending on data given, also drawing graphs helps

yeah, but we know the general idea, so you just fluff it and add a few calculations and formulas here and there..
i hate any writing over 4 marks

 

[Yueyue]

Gets so horrendous when the 9 marker starts to look like an actual essay

yeah a lot of people in my year assumed they could just fluff it for the extended responses in trials and just got completely stuffed by the marking criteria, like obviously fluff is better than nothing but u gotta know all the terminology and details expected to get full marks which is what makes them imo much harder than calcs
