ExplanationThe Vernier caliper measures in increments of 0.01 mm.
#10
In precision measurement, what is the 'zero error' of an instrument?
The error when the instrument reads zero when it should not
ExplanationZero error indicates inaccuracies when the instrument should read zero.
#11
Which of the following is a common technique for reducing measurement errors?
Calibrating instruments regularly
ExplanationRegular calibration ensures accuracy and minimizes errors.
