Explanation / Answer

Algebraic answeR:

(9.8-2.31)/(8.5) = 0.88117 --> 2 sig fig. = 0.88

abs uncertainty --->

0.3+0.01 = 0.31

for division --> (0.31)/(9.8-2.31) = 0.04138

0.6/8.5 = 0.07058

sum = 0.04138+0.07058 = 0.11196

absolute uncertainty --> 0.11196 --> 1 sig fi --> 0.1

% relative = 0.1/0.88*100 = 1.13636 % --> 1 % to 1 sig fig

Q2.

algebraic = 9.2*(5.4*10^-3 + 5.6*10^-3) = 0.1012 --> 2 sig fig --> 0.10

abs --> 0.4/9.2 + (0.3/5.4 + 0.1/5.6) = 0.1168909 --> 1 sig fig --> 0.1

% --> 0.1/0.1*100 = 100%
