Uncertainty is calculate overall not separate lower or upper limit
Thanks for the reply can you also explain how to calculate the uncertainty for M/J 2011 variant 52 Q2)b ) for V/E

Uncertainty is calculate overall not separate lower or upper limit
Im sorry bt im also a bit confused with the absolute uncertainty thing....il let u knw as soon as i find out...
so part 2d...if u rearrange the main equation given to the form y=mx+c...the gradient will be (p/v)....in part d they have given the volume and u have already found the gradient in part c(iii)...so the value of (P) would be volume into gradient.....
uncertainty of V/E=(error in V/V + error in E/E)x(V/E)Thanks for the reply can you also explain how to calculate the uncertainty for M/J 2011 variant 52 Q2)b ) for V/E
uncertainty of V/E=(error in V/V + error in E/E)x(V/E)
I dont think calibration is required just u should know how to calculate value from CROHow do you calibrate a C.R.O with a known light intensity? Could someone explain it to me?
v=.2/thow to calculate v in o/n/11/53??
are u saying that it should be ..[0.5/54.4*10^-2]*1.83 OR [0.5/54.4]*1.83???hey i did this q, its 2012 May/ June,,,,,were u taking inverse of 54.5 x 10^-2 ???or just 54.5, cuz make sure u do, but off course u wud've done it by now
no the error is fine (0.5/54.5) but in calulating 1/L you shud take into account the real value which is 54.5x10^2,,,,so ure error is fine and the value that u quoted 1.83 is good tooare u saying that it should be ..[0.5/54.4*10^-2]*1.83 OR [0.5/54.4]*1.83???
i think he means this:
1st add the uncertainty to the given value = A + a = X
then subtract the uncertainty from the given value = A - a = Y
then subtract the two and and divide by 2 -----> (X -Y)/2
Hope i helped!

Yes... definitely
