Question

Explain my the last digit and a measurement is uncertain

Answer 1

[AI-generated answer — Bot GPT 3.5]

The last digit in a measurement is uncertain because it is an estimate or approximation of the actual value. In most measurements, there is always some level of uncertainty due to factors such as the limitations of the measuring instrument, human error, or the inherent variability in the quantity being measured. The last digit may be rounded to a certain extent in order to simplify the value for practical purposes, but it is important to acknowledge that it is not an exact representation of the true value. Therefore, the last digit is considered uncertain.
