    Fuck a duck. All that time and I screwed up in the second line. Probably a good thing I dont do physics anymore :P

    Check out these wacky keyboards..

    If you mean this http://www.artlebedev.com/portfolio/optimus/ then theyre not LEDs, theyre LCDs - about 50 times the cost. I would guess that keyboard would cost more than $3000 if you could buy it

    got some velocity question with projectile

    The HSC is over for me but not my friends, so solving physics problems on the internet will have to settle for amusement :( a) Vertically the velocity is: 40Sin60 = 34.64m/s Using s = ut + 1/2at^2 25 = 0 + 1/2 * 9.8 * t^2 *** Edit: u = 34.64 not zero. I am an idiot, and the...

    taht 2 tube question?

    Yes, I was referring to the people who got 2000A and 200,000A. Does anyone know if you were actually supposed to halve the 220A since it was only one tube? Physics was my last exam and my brain has purged itself of all school-related knowledge.

    taht 2 tube question?

    Sounds like quite a few people used centimeters rather than meters for the distance... Were you supposed to halve the current? Since the force is only acting on one of the wires rather than both, isnt the current needed half of 220...? Even if I messed that bit up, I found this one of the...

    Aether Question

    And I just found this on the board of studies site: Yes, I know its a bit late, but Im trying to avoid study by posting this. It worked, kinda.

    Aether Question

    The two questions are not linked on the paper, or am I missing something? Sorry to sound like a total idiot, but I still dont understand how to answer that question. Can someone give an example response that would get full marks? [hr] Edit: Helper, I reread your post a few more times and...

    Aether Question

    Thats what confused me originally. Saying that it is invisble, all-pervasive and that light travels though it is really just giving properties. It seems like a retarded question, since the features of the aether model are really based on the aethers properties.

    Aether Question

    This is question 18 from the 2003 HSC: And this is the note from the markers: How would you give two features of the aether model without giving properties?

    Powerplay / Grass Roots

    Is anyone else using Grass Roots as a support text for powerplay? My teacher told me that it is a great text to use for powerplay, and I used it in the trials (14/20, didnt answer the question properly...), but the feedback I got from it isnt all that helpful. Basically I am just arguing...
