Q. What is the greatest possible error for a measurement of 25 centimeters?___ centimeters
Determine Precision: Determine the precision for the measurement of 25 centimeters.Since the measurement is given as 25 centimeters without any decimal places or further precision, we can assume that the measurement is precise to the nearest whole centimeter.Precision: 1 centimeter
Calculate Error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision. In this case, the precision is 1 centimeter, so the greatest possible error is half of that.Greatest possible error =2Precision=21cm=0.5 centimeters
