Question

which of the following measurement is more precise,
(i)2.00mm (ii)2.00cm (iii)2.00m

Answer 1

The word accurate is a synonym for precise. So the most accurate (or precise)
answer is 2.00mm& because it& uses mm (smaller unit then m and cm) as a
measurement unit. We assume that given results are rounded to corresponding units(i.e. (i) to the nearest m, (ii) to the nearest cm, (iii)to the nearest mm).
