Students have asked these similar questions

A known accurate measure of physical quantity is termed as a standard. These Standards of Measurement are used to determine the values of other physical quantities by the comparison method. Also, depending on the functions and applications, different types of standards of measurement are classified in categories. State the frameworks of the International Standards, Primary Standards and Secondary Standards of measurement.

a) how many significant figures are in the numbers 999.0 and 1000.0? b) if the uncertainty in each number is 10, what is the percent uncertainty in each? (Give your answer to 4 significant figures) c) which is a more meaningful way to express the accuracy of these two numbers, significant figures or percent uncertainties?

It is your responsibility to determine the three fundamental quantities.
