Please fill in/answer the below questions.
**Understanding Significant Figures and Uncertainty** This table illustrates a fundamental concept in scientific measurements: significant figures and uncertainty. It is essential for ensuring precision and accuracy in scientific data. | Underline Significant Figures | Underline the Uncertain Number | Write the Uncertainty | |-------------------------------|-------------------------------|-----------------------| | 24040 | 24040 | | | 0.04800 | 0.04800 | | | 4.020 | 4.020 | | | 1.08 x 10^-5 | 1.08 x 10^-5 | | | 0.0022 | 0.0022 | | | 9000000 | 9000000 | | | 2.00 x 10^-5 | 2.00 x 10^-5 | | | 8.60 x 10^2 | 8.60 x 10^2 | | | 0.000460 | 0.000460 | | | 2.50 x 10^2 | 2.50 x 10^2 | | | 129.000 | 129.000 | | | 55980 | 55980 | | **Explanation:** - **Underline Significant Figures:** This column identifies which digits in each number contribute to its precision. These are the measured or known figures. - **Underline the Uncertain Number:** This column highlights the number that is uncertain or estimated. In scientific measurements, this usually involves the last significant figure. - **Write the Uncertainty:** Although this column is left blank in this table, typically, uncertainty is expressed as a range or margin of error, indicating the reliability of the last significant figure. Significant figures reflect the precision of a measurement, while uncertainty provides insight into its accuracy and reliability. Understanding these concepts is crucial for data analysis and interpretation in experiments and calculations.
