Q. What is the greatest possible error for a measurement of 2 metric tons?____ metric tons
Determine precision: Determine the precision for the measurement of 2 metric tons.Since the measurement is given as 2 metric tons without any decimal or further precision, the precision is to the nearest whole metric ton.Precision: 1 metric ton
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.Greatest possible error =2Precision=21 metric ton=0.5 metric tons
