    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive From Success One: "The students claim that a DC generator is an electric motor in reverse is basically correct. The components in each are almost identical but, with the generator, work is done to supply the mechanical energy to rotate the coil, which then...

    OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!!!!!!

    Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! the fuck, i'd be so happy with a 90 lol

    When to start past papers?

    yep ASAP, as an accelerated student you should be smashing out double if not triple the amount of past papers that actual year 12's are doing. Accelerated subjects are a priceless opportunity so don't let a single moment go to waste!!! much ragrats from me lel

    A collection of HSC Advice: What *not* to do

    Consistency is key. Always aim to be fully understanding what you've learnt in class, do extra work at home so that you won't be trying to cram actual content couple days before exams. A mistake most of us are undergoing right now. This is especially important for high content based subjects...

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive Analyse Einstein's Theory of Special Relativity and the evidence supporting it as an application of this model of scientific method. Can someone do this please? Or write up a plan/summary

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive i'll try my best lol: A black body is a theoretical object that absorbs all incoming radiation, as radiation is absorbed the black body is heated and begins to emit EM radiation at a range of frequencies -- therefore the wavelength of radiation will vary with...

    re: HSC Physics Marathon Archive might need to mention ultraviolet catastrophe and how quantum theory explained this, not too sure though i'm also shit at this

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive Effects on Society: - Since voltage & current could be increased & decreased, power could be efficiently transported over large distances - Allowed power stations to be located away from suburban areas and closer to resources needed to generate them (coal and...

    re: HSC Physics Marathon Archive 1 eV (electron volt) = 1.6x10^-19 J, so just times by charge of electron, not sure about Hz

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive Thermionic devices involve two or more electrodes (heated filaments) enclosed in an evacuated glass tube. An electric current acts as a heating mechanism that heats the filament, effectively causing it to liberate electrons and hence act as a cathode -- this is...

    re: HSC Physics Marathon Archive F=BIL=ma, a=ILB/m v=u+at, u=0, v=ILBt/m Sub t=100ms? to the right (RHPR) - nvm got beaten to it

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive if you follow the wire and think about a physical image, the negative terminal for A is coming out form underneath and coming from above in C, changes your right hand grip rule

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive this shit tripped me out yesterday, I got a reason to why it's B but am not sure if it's legit lol. I pretty much used the right hand grip rule on the windings to determine the polarity of the magnets, then used right hand palm rule to determine whether the...

    re: HSC Physics Marathon Archive never really seen transformers paired with microchips/processors? Pretty sure he meant transistors

    I accelerated 3U, got 94 exam mark but dragged to a 92, but said yolo and kept it lol

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive Ux = Ucos60 Uy = Usin60 Use delta(x) = Ux*t in order to find t in terms of U Then use delta(y) = Uy*t +1/2(ay)(t^2) and solve for U

    Will you stay on BoS after your HSC?

    I'd probably stay for the uni forums actually and maybe occasionally give some HSC kids general advice. Not gonna help with any content or actual work tho fuck that, gonna wipe dat shit from my memory asap
