    Hamlet Predictions

    markers notes last year say they were annoyed that people only talked about hamlet reference to another character seems likely

    comprehension texts as a related for discovery

    Since MOD C is about how composers forge representations of the land, would it be unwise to use two of the same form?

    comprehension texts as a related for discovery

    As if everyone wouldn't just use a comprehension related then? So much easier to pick techniques that fit the question when you have the text in front of you, and you can use the same analysis 3 times lmao

    comprehension texts as a related for discovery

    yay or nay, if they asked for a second related can I just pick one of the ones from short answers also if they asked for two is using two of the same medium a big no, EG: two short story related or two paintings

    2001 cutoffs

    I got 101 for the test and im aiming for a 92 if that gives you a general idea

    re: HSC Physics Marathon Archive It's a syllabus dot point, lol also you forgot mention the high potential difference

    When was gray's poetry written

    The date each poem was published does not appear to be anywhere on the internet, it is no where to be found on the board of studies either.

    2 quick fire questions

    Also is it ok to have a title for a creative? Is it frowned upon in some respect as it kind of shows you have a prepared creative?

    Time Dilation Q

    I'm guessing what I did works as an approximation when the ball isn't going at relativistic speeds itself then? There is no other way within the course you could possibly do that question, and I'm guessing the ruse teachers intended it to be done this way

    Time Dilation Q

    no... if the ball was moving at 0.5c, you would use what I did above and then you get the ball moving at 0.32c THROUGH THE SPACESHIP relative to earth. That's not accounting for the fact that the spaceship is also moving, you then need to add 0.6c to that and the ball is then moving at 0.92C...

    Time Dilation Q

    The speed of the ball moving through the spaceship is 0.064c, as worked out using relativity laws that we learn in HSC physics. But of course the reason we are using relativity laws is because the spaceship is also going at 0.6c away from us. So the spaceship is going away at 0.6c, the ball IN...

    Time Dilation Q

    let distance of the spaceship be x, use length dilation, it is 0.8x let time taken for the ball to reach the end be t, use time dilation, it is 1.25t v=d/t=0.64 * speed of ball from frame of reference of spaceship=0.064c from frame of reference of earth add to 0.6 and you've got your...

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive But how do you show e=hf is the reason the graph drops off after UV, instead of going up to infinity like a y=1/x graph? When I saw a question like this in success one, they just said Planck devised a 'mathematical formula' to explain the UV catastrophe, and the...

    re: HSC Physics Marathon Archive You should mention that the beams fired at the nickel crystal were monochromatic (in faze), and the x-rays were used as they were similar to the spacing between the nickel atoms which is deal for diffraction. I guess you could also draw a diagram the fully...

    re: HSC Physics Marathon Archive How would E=nHF explain the UV catastrophe?

    'Donor level' and 'acceptor level'

    Easy way to remember is that the N-type provides an extra electron that can be liberated to the conduction band with little energy. This means that the donor level is close to the conduction band, as that illustrates a small to negligent energy gap.

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive My understanding is E=hf actually has nothing to do with solving the UV catastrophe, or at least not that formula directly. The actual formula he used to explain it isn't in the course but with a quick google search I'm guessing its the first one on here...
