Chapter 2.4, Problem 6QQ

Interpretation Introduction

Interpretation:

The uncertainty in the measurement 56.00 is what value has to be selected from the given options.

Concept Introduction:

Whenever a measurement is made, the significant figures in the measured quantity give the actual measurement.  For this the significant figures should be recognized first. The significant figures may be non-zero digit and zero digit.  But Zero may be or may not be a significant figure.  The number of significant figures gives more information about the degree of uncertainty.  This uncertainty is determined from the last digit.  One should also note in which place the last digit appears, either in the tenth, or hundredth or thousandth place.
