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.

Question
Two different measuring devices are used by students to measure
the length of a metal rod. Students using the first device
report its length as 0.5 m, while those using the second report
0.502 m. Can both answers be correct (choose one)? (a) Yes,
because their values are the same when both are rounded to
the same number of significant figures. (b) No, because they
report different values.
