I'm probs gonna be there this year so idk why you wouldn't goconsidering whether i should attempt boredofstudies trials
i dont want to get wrecked though

aww bbyI'm probs gonna be there this year so idk why you wouldn't go
Ended up going home at like 10, didn't die so :')))))You actually made it home without being kidnapped?
Superconductors have a permeability of very close to zero. This means that superconductors exclude all magnetic fields within the superconductor itself.aww bby
naw i meant that older past papers for 2U, I've been saving them up until I'd done a lot of other trials. I feel comfortable doing hard trials (syd boys, grammar) and getting 97+, so I figured I might try
actually, can you (or anyone) help me with the meissner effect. the way I understood it with eddy currents is apparently wrong :O
You are way better off than me. I literally woke up at 4.30 am this morning and am FINDING quotes and themes for my set text and ORT for the section 3 essay of paper 1 which is on the same day. That is the definition of unprepared. So screwed.Ended up going home at like 10, didn't die so :')))))
Would've actually stayed there longer but kinda felt bad since the staff were packing up and there were like 2 other customers there - one of which was another yr 12 prepping for trials kek she was there longer than I was

Feeling so underprepared/10 still need to memorise all my quotes smh
Though it was recent, all I learnt was that the superconductor had the ability to exclude external magnetic fields. We deduced that there wasn't such things as eddy currents going on at all?Superconductors have a permeability of very close to zero. This means that superconductors exclude all magnetic fields within the superconductor itself.
However, on the surface, the permeability is not necessarily zero. The permeability decays exponentially as you get deeper and deeper from the surface (research London penetration depth).
So surface currents directly on the superconductor's surface (or very close to it, typically no more than 500 nm) are induced. These surface currents repel the external magnetic field.
Hence, no current is actually induced within the superconductor itself and hence you can't state that eddy currents are induced throughout the superconductor. The currents are only on the surface and NOT throughout the superconductor.
Next time, make a thread. I only just saw this by luck. You and others will benefit much more by making a thread on it and waiting for a reply.
Just read past HSC paper solutions and memorise the explanation that the Board of Studies wants you to memoriseaww bby

amen brudahfucK trials
i remember watching this vid where this one girl could remember every little thing from her life - id legit give $15.40 to be her for the rest of my HSC ;(
yea, still need to finish my mod c essayDo you guys have Paper 2 day after?
You got the CSSA paper too... The poem was painful lol. Everything else was ok though. I totally just winged my creative writing story, even though I really know I shouldn't have. But our exam was weighting like 5% (Paper 1), and Paper 2 has 15%. So I really thought screw it, idc about Paper 1, I'll just focus on Paper 2.amen brudah
comprehension was bullshit, not sure if you guys got the same poem about the disciplined guy in a box
