    Undergraduate application

    Oh, do watch it however because IIRC your UAI will be rescaled to match the standards of the students this year - so your mark three years ago might not be as hot today (or it might be better, but I don't know actual trends). You haven't talked to the course co-ordinators yet? You WILL be...

    Ah, something wrong with bos today

    "Of course, I regularly answer questions before they are posed. I'm clearly psychic." Another issue with the forum clock happened back in '02... can't remember what it is though, but it's not the same issue.

    Hsc Trial Question

    Perhaps one more note not in relation to question: - mutations in non-coding segments often still affects the outcome (!) because much of the regulation happens outside of the coding region. Do not be mislead as to the historical error that non-coding = useless. The timing and amount of...

    Natural radioactivity means that some atoms are unstable as found in nature, and will decay.

    Re: Few questions.

    Relative to the vehicle, you need to reverse the velocity of the observer, which is the vehicle. (i.e. relative to the vehicle, everything that stands still is travelling 9 ms.-1 due West already) Then add tail to head in whatever order. You derive veocity = sqrt( 9^2 + 12^2 ) = 15 ms.-1...

    hyperbola

    Asymptotes at x = -1, so it's not just a hyperbola... will edit in a while to find intercepts. EDIT: does NOT appear to asymptote at x = 0.... Has positive x and y intercepts. x=0 does not diverge ecause of the way (0)/(0) will cancel out to some constant value. This y-intercept appears...

    Velocity problem

    I'll express this in an equation: Research + teaching labs I studied for the year before + sitting around waiting for simulations to finish (because they so slooooww..) + visiting friends at many churches + picking up guitar again + everything else that is happening = magnificent! You are...

    B. Medical Science - 1st year program

    There are usually quite a few in each year for B Science (adv.), which is possible if you make "the marks you will get" a primary concern. However, this is possibly unheard of in medical science - there are a LOT of fields to consider: for a start, people will pass physics or biology, possibly...

    column chromotography

    Practically speaking, if you can't see the components you'll need to prepare a series of small flasks to swap over as you conduct the experiment. The faster component(s) will come out first, which will be contained within the first # of flasks, and the slower one will be contained in a a few of...

    Same thing. You can't get fission reactors without it being nuclear.

    Velocity problem

    Because the answers are wrong. I got v = (1250+1500)* 7 / 1250 = 15.4.

    Japanese in the Future

    Coming from the other side, I haven't really used it since high school.

    Best building on campus

    Uh, I meant on the poll. As a joke. But thanks anyway - apparently Transient houses graduate psychology. Architecture is probably the ugliest building in USyd, taking into account its name. It sits somewhere between Seymour and Wentworth on City Road.

    Parallel wires question

    No, xiao, that's no way to treat your younger compatriots. :p

    Buffer Solution ...

    Weak acid and its conjugate base is the better answer. Example: a phosphate buffer used in most biochem labs Na<sub>2</sub>HPO<sub>4</sub>. Well, it can be a weak base and its conjugte acid - if you can find the example.
