    Question: Locus & Parabola

    Let P have points at (x,y) I would assume that u would know the distance formula, so just use that, but since u r squaring it, then u do not need the square roots. From then on, just simplify. and then make y in terms of x and then u should have ur locus. if u dont know what distance formula is...

    Simple question on eco growth and environment

    FIRSTLY, 'velocity' is wrong, increasing economic growth does not provide INCREASED spending on environmental protection, because from the PPC as EG increases the funding for EP decreases. Therefore there is not positive impact for EP, because as we increase EG we produce more goods and...

    dot point help

    the main reason superconductor would be considered beneficial for society is that it has zero resistance, and with zero resistance and the flow of cooper pairs without the generation of heat, allows better flow of electricity. Transmission lines- with super conductors there would be no heat...

    2 simple questions need to clarify

    i am just remember planks constant as 6.626e-34 off the top of my head so if i am wrong tell me..... Threshold F Using E=hf - work constant therefore when E=0 0=(6.626e-34)f - (3e-19) therefore u should get f= 4.5e14 as threshold frequency Threshold wavelength Using c=f lambda...

    how about... x/(x^2 + 2x -2)
  8. A

    Integration again

    actually i know how to do it now..... here is another one 1/(x^2 +x +1)

    effects of inflation?

    Superconductors

    I dont think so, you only need to know their properties, common examples and what critical temperatures are, becasue i have looked through some past HSC papers and they had tables of superconductors which are given to u. In other words all u really need is the scientific development of...
