Answer:
the instrument that gives this precision is the micrometer screw
Explanation:
The high precision measurements of small parts are the general vernier and the micrometer screw.
In these two instruments the same principle is used: there is a fixed rule and a mobile one that increases precision.
Let's analyze the absolute error or precision of each instrument
* For the vernier, the precision of the fixed rule is 1 mm and there are 20 divisions (the most common); therefore the precision of the instrument is
Δx = 1 mm / 20
Δx = 0.05 mm
* For the micrometer screw, the precision of the fida rule is 0.5 mm and the number of divisions is 50, therefore the precision of the screw is
Δx = 0.5mm / 50
Δx = 0.01 mm
consequently the instrument that gives this precision is the micrometer screw
