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: ± .07 percent relative uncertainty: ± 8 % 9.2(±0.4)×([5.4(±0.3)×10−3]+[5.6(±0 .1)×10−3])= 0.06 absolute uncertainty: ± percent relative uncertainty: ±
