Concept explainers
Interpretation:
This is to be explained that all the measurements are uncertain.
Concept introduction:
The term accuracy is mostly used for the difference between a measured result and the actual exact result.
Answer to Problem 1RQ
For certain calculation, there is a chance to have the difference between the calculated value and actual values. Hence, all measurements are uncertain.
Explanation of Solution
Most instruments also have a degree of accuracy and student can be sure of how accurate something is up to that degree. A ruler has a degree of accuracy down to a millimeter in which one make a guess between values of millimeters.
For any experiment, there is some error that can be possible which results the answer to vary from the true value that means uncertainty occurred.
