What is the Relative Uncertainty and Absolute Uncertainty?
log (104 plusminus 3 / 8 plusminus 1)
10^ (1.234 plusminus 0.001)
a)
log (104) = 2.0170333393
log(104 + 1.375) = 2.02273758763
log(104 - 1.375)= 2.01125317013
absolute certainty = max( 2.02273758763 - 2.0170333393 , 2.0170333393 -2.01125317013)
= max( 0.00570424833 , 0.00578016917)
= 0.00578016917
relative uncertainty
= 0.00578016917/2.0170333393
= 0.00286567854
b)
10^1.234 = 17.1395730751
10^ 1.235 = 17.1790838716
10^1.233 = 17.1001531509
absolute uncertainty = max( 17.1395730751 - 17.1001531509 , 17.1790838716- 17.1395730751)
= max(0.0394199242, 0.0395107965)
= 0.0395107965
relative uncertainty
= 0.0395107965/ 17.1395730751
= 0.00230523807
= 2.3%
