    Mechanics PAPER4 2009/ 41

    Resolve both tensions [call them T1(tension in the shorter string) and T2(tension in the longer string)] into vertical and horizontal components. As the system is in equilibrium, the horizontal components of T1 and T2 are equal this gives you an equation T1sin36.9 = T2sin53.6 which simplifies o...

    Physics Paper 1

    about may june 06 Q 24, the amplitude doesnt double as the intensity doubles. Say for example the initial waveform had and Intensity I with A =5 thus I=k(5)^2 (since Intensity depends on the square of the amplitude- hence the constant k comes out to be I/25. Now in the second wave the 2I=kA^2...

    Chemistry Applications

    Is the booklet sufficient to study NMR spectroscopy? And can someone please tell me which part do I focus on in the bit on 'Green Chemistry and Sustainability where they talk about Oil Slicks, Flourinated boons, its just so much to learn :S

    Trig Identities Maths easy.

    cos@/sin@ - sin@/cos@ (cos^2@ - sin^2@)/sin@cos@ As the numerator is equal to cos2@ hence cos2@/sin@cos@ Multiply numerator and denominator by 2 you get 2cos2@/2sin@cos@ (Sin2@ =2sin@cos@) it becomes 2cos2@/sin2@ which equals RHS

    Angle between tangents/line. Math P1.

    The gradient is also defined as Tan (Theta), thus you should find the gradient at a point on the curve and find tan inverse of that gradient. The angel you get is the angel made by the tangent (at that point on the curve) with the x axis, it helps to extend the line to the axis and draw the...

    Organic Chemistry

    Can somebody please tell me... when we react say aq. Bromine with 4-Aminomethybenzene, do the Br groups join the ring relative to the Amino group or the Methyl Group? (both are 2,4 directing groups)
