i dont understand how least count helps us to take a reading from a vernier calliper. i mean, what is the importance of least count, in taking readings from a measuring instrument. thank you.

can the physical balance measure both mass and weights??

give a reason !!!

Name the instrument used to measure

1. diameter of the needle

2. thicknesss of the paper

3. diameter of a pencil

4.depth of a beaker

5. length of a table

6 diameter of a bob

 are there any precautions 2 take before using the beam balance?

define unit ?

A Stop watch has a circular dial divided into 120 divisions. What is its least count?
