Webb4 mars 2024 · 1. The uncertainty of a rule is the smallest division, because a length is the difference between two points. The right-hand end of the object is 4.35 ± 0.05 (in the corresponding units), but the left-hand end is subjected to the same uncertainty. Therefore, the length of the object will be. ( 4.35 ± 0.05) − ( 0.00 ± 0.05) or 4.3 ± 0.1.
