## anonymous 4 years ago what is the precision for a meter stick, vernier cailper, and micro

1. anonymous

*micrometer

smallest unit of measurement on each of these, on a meter stick its generally 1mm as long as you're using metric, not sure what the smallest unit of measurement on the other two are, but whatever that is is the precision.

okay thank you can you help me figure out what the relative uncertainity of an object of length 2 cm what is the the relative uncertainity is we use the above instruments

4. anonymous

if you measure it to be 2cm with any of the above instruments then the measurement will look like this $2cm \pm precision ~~\text{or }~~2cm \pm uncertainty$ so report plus or minus your precision as your uncertainty.

for meters what would it be
