Q. What is the greatest possible error for a measurement of 2 tons?____ tons
Determine Precision: Determine the precision for the measurement of 2 tons.Since the measurement is given as 2 tons without any decimal or fractional parts, the precision is to the nearest whole ton.Precision: 1 ton
Calculate Error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the precision.Greatest possible error =2Precision=21 ton=0.5 tons
