Science 10: Signifiant Digits?? Help please if you understand how to do it.?

Significant Digits
Scientific measurement are always uncertain. Even the best measuring instruments have limitations, and readings from them always contain an estimated digits. One way to express the degree of uncertainty is by counting the number of significant digits in a measurement. More significant digits means greater certainty.

2. The diameter of a pipe is measured as 2.54cm using a ruler. Using an electronic caliper, the diameter of the same pipe is read as 2.5431cm.
a. In each measurement, which digits is uncertain?
b. Which emasurment has less uncertainty? How do you know?
c. Which measuring instrument is more precise? How do you know??

Also explain please, I'm confused about significant digits.

Digits imply Precision...

BUT certainty is closely related to accuracy...

Precision and accuracy are NOT the same...

An instrument can be way off in accuracy but still be very precise...
