Write down whatever you know the most about

I feel like the amount of careless errors i make is independent of the amount of papers i do. How would you guys tackle this problem?

Re: HSC 2015 4U Marathon Ahh i see, i was just confused due to the +/- sign, so the outer radius assumes the larger x value - therefore a + sign?

Re: HSC 2015 4U Marathon need help with this: volume obtained by rotating (x-1)^2+y^2/4=1 about y-axis using slices

Yup, 2u don't have those log laws, so i dont think you can use it either

Not inside core, not sure about optionals though (Although you might want to remember what some esters smell like?)

Hmm, right now, it seems like you're stressing over your work ethics and looking for alternatives. Tbh, if you can trust yourself to do a set amount of past papers every week under exam conditions, i think your problem should be easily solved. Be confident in your methods, i guess thats how i...

Re: HSC 2015 4U Marathon Yeah i got to there, but im not sure where to go lol should i let u=x-2 then do another trig sub, then reverse everything back

Re: HSC 2015 4U Marathon integral of sqrt(5-x^2+4x)

Ay sleepingking, i got exactly the same assignment question. do you go to my school rofl?

Hey Fizzy, how do i approach the magnetic levitation experiment and background information on this? We can only use type II's for experiments, but the explanation for the 'levitation' that occurs in type II's is vastly different from type I's (which is the expected explanation)

At HSC level: Changing Magnetic fields induce currents in the super (F-law). The currents flow in such a direction such that the magnetic field it creates opposes that which created it (L-law). This causes the Meissner effect such that no flux lines can penetrate it. The upward magnetic force...

Sadly, i need to explain this (part of an assignment) and I can't fathom how I can shorten vortex states, flux pinning, incoherent Meissner effects and everything else into 150 words. should i consult my teacher lol

wot happened carrot, LOL

Basically, since BCS theory is only applicable to type I, how do I explain the occurrence of the Meissner effect in a type II?

So I have to design an experiment to demonstrate magnetic levitation. However, how do I explain the results obtained using a type II superconductor? And how do I hypothesise about the physics behind this?

Solid advice, thanks hawkie

Well, to cut down time for revision, question yourself all the dotpoints and see if you can answer them in a succinct manner by writing it on paper. If this seems too tedious, you can do past papers first. Now, for every question and respective dotpoint that you are unfamiliar with since you...

Or if you have any specific questions you can always PM me and ill try to help

Get your textbook, notes from peers or internet or anything else at your disposal. Track down the dotpoints that you think you've missed and write up something
