Are the ones answered also correct?
The precision of a measuring device is given by the difference between two consecutive indicated measurements. In other words, how far apart are the closest indicated values or markings. For example, there are tick marks every millimeter on the ruler. At times, a measurement can be estimated to a smaller difference, but the precision of the device is determined just from the indicated values. What is the precision of the ruler? What is the...
