Question

Two mechanical devices typically used in laboratories to accurately measure small objects or distances are the

Answer 1

Micrometers and Calipers

Step-by-step explanation:

A micrometer can be sometimes called the screw gauge micrometer. It is a device which consists a calibrated screw, which is widely used for measurement of component accurately.

Micrometer can also be used in microscopes to calculate the apparent diameter of microscopic bodies.

A caliper is a device which is used to measure the distance between the 2 opposite sides of small objects. It is mainly used in mechanical engineering, forestry and the labs.
