Two students measure the length of the same object. If the students reported measurements of 3 m and 3.01 m, do you think one of them has made a mistake? Explain your reasoning.

Yes, one of them made a mistake

Explanation:

Even though, the two values obtained in the measurements are close, the student that reported 3.01 m made a mistake.

A meter rule that is calibrated in meters (m) will only have an accuracy of 0.1 m, hence can be read as 3.0 m, 3.1 m, 3.2 m, 3.3 m and so on. A meter rule that is calibrated in meters cannot provide accuracy of up to 0.01 m, hence the student that reported 3.01 m could not have been sure of the .01 added as it couldn't have been read on the meter rule.

NOTE: A meter rule (popularly known as ruler) is an instrument that is used in the measurement of the length of an object. It can be calibrated in centimeter, inch or meter.
