    chemistry paper 42

    I know.... Last year for O/N 2013 paper 4s, IIRC the threshold is around 65s.... But this is soo hard.. :( So based from the previous thresholds (and isn't the syllabus changed for this exam session?), then I guess it will be around 55-58.

    Physics: Post your doubts here!

    Have you changed the units to m for the diameters and length? Btw its my way: R=p*l/A 7.5=p*(1750/1000)/(phi*(0.5*0.38*10^-3)^2) 7.5*phi*(0.5*0.38*10^-3)^2=1.75p p=7.5*phi*(0.5*0.38*10^-3)^2/1.75 p=4.8604*10^-7 ohm m.-->4.86*10^-7 ohm m Hope this helps! :D
