3. you are measuring a distance using a caliper to measure something and you measure it to the nearest 0.01 mm. however, you have misread the scale and listed the measurement as 8.62 mm when it really should have been 9.62 mm. is this a mistake in accuracy or precision, or both?

Answer

Vernier caliper measure nearest to 0.01 mm.

If the correct reading of the experiment is 9.62 mm.

But you misread it and listed it as 8.62 mm.

This is Clearly the case of mistake in Accuracy.

Because the reading is wrong and answer is not accurate hence it is mistake in accuracy.

To Judge weather the reading is precise or not we should have a range where the result is acceptable but in  the question no range is given. So, we cannot comment on precision.
