what determines if a measurement taken from a measuring instrument has an uncertainty digit? how does the uncertainty digit affect the number of significant figures that measurement has? explain your answer.
Answer
Brief Explanations:
The uncertainty digit is the last digit in a measurement. It is estimated by the person taking the measurement. For example, if you measure the length of a table with a ruler that has markings every centimeter, you can estimate the measurement to the nearest millimeter. The number of significant figures in a measurement includes all the certain digits plus the one uncertain digit. So, the uncertainty digit is part of the significant figures. It determines the precision of the measurement. If a measurement has more significant figures, it is more precise.
Answer:
The uncertainty digit is the last digit in a measurement, which is estimated. It is included in the significant figures. The number of significant figures is the number of certain digits plus the one uncertain digit. So, the uncertainty digit affects the number of significant figures by being one of them.
