Length, or the distance between two lengths: Tools used to measure length include a ruler, a Vernier caliper, and a micrometer screw gauge. Vernier calipers and micrometer screw gauges are more precise and can be used to measure the diameter of objects like pipe and wire.

What is the function of apparatus?

The Golgi apparatus is an organelle present in most eukaryotic cells. It is made up of membrane-bound sacs, and is also called a Golgi body, Golgi complex, or dictyosome. The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell.

How do I calculate least count?

The formula of Vernier calliper least counts is determined by dividing the smallest reading of the main scale with the total number of vernier scale divisions. The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm.
