Which best describes accuracy? a. the smallness of the graduations on a measuring tool b. the reproducibility of a measured value c. the dependence of a measured value on a controlled value d. the agreement between a measured value and an accepted value

Accuracy is defined as the closeness of the measured value to the actual value. Therefore, out of the options, this is best described by A. the smallness of the graduations on a measuring tool. This is because smaller graduations mean that the value can be measured to a smaller level, making it more accurate. Moreover, smaller graduations are able to detect smaller changes, increasing the accuracy of the instrument.

The answer is B. Accuracy is how much the consequence of an estimation, computation, or detail fits in with the right esteem or a standard. Exactness relies on upon how the information is gathered and is normally judged by looking at a few estimations from the same or distinctive sources.

The answer to that would be magnesium
