Question

Perform the calculations and determine the absolute and percent relative uncertainty. Express each answer with the correct number of significant figures. To avoid rounding errors, do not round your answers until the very end of your calculations.

[9.8(±0.3)−2.31(±0.01)]8.5(±0.6)= 0.88

absolute uncertainty: ± 0.07

percent relative uncertainty: ± 8 %

****9.2(±0.4)×([5.4(±0.3)×10−3]+[5.6(±0.1)×10−3])= _____________

absolute uncertainty: ± 0.005

percent relative uncertainty: ± 5 %

Answer 1

Firstly, It looks like there is a typo in the sample problem:

It should be [9.8(±0.3)−2.31(±0.01)] divided by 8.5(±0.6)= 0.88
