    T1 and T2

    nwz..um in 2005 it came it was 2 marks, even then it was an application question u could pretty much make it up on the spot

    T1 and T2

    T1 and T2 are relaxation times . By distinguishing between the relaxation times of different tissues, computers can determine the type of tissue and thus produce an image. T1 images are produced by rapidly turning the radio pulse on and off. As a result T1 tissue continuosly energise and relax...

    the aether

    hey guys i just wanted to ask a quick question...a property of the hypothetical aether was that it has to be very elastic to allow the propagation of light..why does it have to be elastic? for wat wave property does this feature accomdate? thanks =)

    Photoelectric effect question

    I believe both an increase in intensity and frequency would yield a larger photocurrent: Increase in intensity; would mean more electrons are being librerated as there are more photons bombarding the metal surface. Since current is a flow of electrons, the more electrons that a liberated the...

    graphs

    y=e^f(x) 1. when f(x) = 0 , y=1 2. y CANNOT be negative, a good way to check if ur graph is correct or not. y=ln{f(x)} 1.When f(x) = 0, a vertical asymptote exist at the corresponding x value 2. When f(x)=1, y=0 3.f(x) CANNOT be < 0, to draw y, in other words whenever f(x) is <0 ignore dat...

    roots of equations

    hey guys, just wanted to ask a quick question. if you had to find the sum of the roots of the equation x^3-3x+5=0, how do u got about doing it since in this particular question the powers of x do not fall from cubic to quadratic to linear, rather it falls from cubic to linear. in other words...

    Estimate your Raw Mark

    ah sorry must say an agar plate in a closed petri dish
  13. H

    Estimate your Raw Mark

    welll if u said a petri dish containing the nutrient agar it would be allright it depends entirely on how u set out ur procedure to investigate microbes in drinking water

    ~~Mathematics Revising Game~~

    ive attached the solution to the derivative question 2e^2x - e^x = 0 e^x(2e^X-1)=0 e^x=o has no solution 2e^x=1 e^x=0.5 x=ln0.5

    ~~Mathematics Revising Game~~

    if u mean for the question :find the derivative of y=ln(e^x sin^2 x) thats incorrect...u should start off with y'=u'v+v'u ---------- f(x)
