The sensitivity of a measuring instrument is the value of the smallest quantity that can be read or estimated with it. What is the smallest part of a centimeter that can be read with the following?
(a) a meterstick with markings at each millimeter
I tried
.01 mm
.05 mm
.1 mm
.01cm
all wrong..
(b) a digital caliper with a fourdigit display
I tried
.0001 in
.01 mm
.01 in
all wrong as well

For a I would think it could be estimated to the nearest 0.5 mm which is 0.05 cm.
For b, the problem doesn't say what the digits mean; i.e., fourdigit display of what length? If it is 1234 then it can be read to 1 in the last place, whatever that last place is.
