please see ms. ans is really confusing. it seems error is divided by 10.Got your question!!!!!!!!!!!
Error in T=(error in t/t)xT (10 is constant so has no error)
For error of T^2=(2(error in T/T))xT^2
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Q1. How do we change the speed of the rotating device?
Yes or u can change the setting on the fan.Fan has a motor. How do you change it's speed?
Use a variable resistor.
lets take t= 50 +- 0.2Did u even try doing it????
I got answer correct by this way and verified by marking scheme.Constant dont contribute in the errors.
Assalamoalaikum
can anyone plz tell me how to find the absolute uncertainties in Q2b
http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s10_qp_51.pdf
Xc = V0 / I0
So, (Error in Xc) / Xc = [ (Error in V0) / V0 ] + [ (Error in I0) / I0 ]
eg for first row:
Error in Xc = { [ 0.2/5 ] + [ (0.2x10^-3) / (15 x 10^-3) ] } x 330
Error in Xc = 18
Hope that helped
thanx alot
can u also plz tell me how to do Q2 e
