    The Transistors In Australia question

    Shouldn't be too big a problem, since I related it to why they replaced thermionic valves :)

    Principle of Relativity (Inertial/Non-inertial)

    Yeah I also referred to the Special Theory.

    Advice on yr 11 and 12 biology

    If you liked the biological section of science then do bio. Just do bio if you like it. yr 11 will be boring as an arbitrary opinion, but the hsc course is the most interesting one!

    Drop jpn continuers enrol in beginners instead yr 11?

    FML, I missed out on Music then xD Oh well, my Japanese teacher is REALLY good anyway so I don't care ;)

    Yeah you're right. Plus, there are still lattice distortions due to the BCS theory :) and... Baha, epic we got a sticky.

    The Transistors In Australia question

    I referred to the heat resistance of solid state devices such as transistors and related it to the unpredictable Australian climate xD

    Principle of Relativity (Inertial/Non-inertial)

    Same, I was thinking about writing that you couldn't tell you were in an inertial frame of reference but my experiment (holding a mass tied to a string in a moving bus) would be contradicted xD Would my experiment be right though? As in, I am referring to the frame of reference of the mass?

    The course also says that Force due to gravity exerted by any object on another is equal to (Gm)/r2, or at least it is implied you know how to derive that equation. Judging from the picture, this is probably the sort of information the examiners wanted us to regurgitate, I think you're...

    Yes, but if you find the conventional current, the electrons will be concentrated on the opposite side of the conductor. There's also the case of whether or not eddy currents are formed, which people seem to keep ignoring me about xD Also, what about the poor physics ladies xD

    Nice resource, but does the same apply for a thin conductor?

    If you're talking about Q9 (it referred to a thin conductor, so I'm not sure), then there was a velocity indicated down the page.

    Sure, the Earth moves between the sun and the moon but at the same time the moon is orbiting the earth because it is a natural satellite lol. That may be where you're a bit confused. Think about if it was a solar eclipse (I think this is an alright analogy), then the moon would have...

    If anyone can tell me EXACTLY which direction the force is, I may be able to help. Otherwise, I interpreted the thin conductor as a medium for eddy currents XP

    By the formula for gravitational attraction the Sun affects the force. Hence, it is B, as the distance between the sun and the moon has increased.
