- Two different measuring devices are used by students to measurethe length of a metal rod. Students using the first devicereport its length as 0.5 m, while those using the second report0.502 m. Can both answers be correct (choose one)? (a) Yes,because their values are the same when both are rounded tothe same number of significant figures. (b) No, because theyreport different values.A lecture period (50.0 min) is close to 1.00 microcentury. (a) How long is a microcentury?
