Question

Meter scale is used to measure ______________.

Answer 1

Hint: Measurement is determination of the magnitude of any physical quantity. The device used for measurement should be available easily. Example: Wooden scale is easily available.

Complete step-by-step answer:

There are seven fundamental physical quantities. These fundamental quantities are: Length, mass, time, temperature, current, amount of substance and luminosity. The unit of these fundamental quantities are: Meter, kilogram, second, kelvin, ampere, mol and candela respectively.
Length is one of the fundamental units in the system of measurement. The SI unit of length is meter. The meter scale is the apparatus for measurement of the length of any object. Example: The length of the square is 5 meters. Here, 5 is the magnitude of the length and meter is the unit of length. 1 meter of the meter scale is divided into 100 centimeters.
Meter scale is used to measure Length.

Note: The meter scale reading does not change with temperature and other physical quantities. The scale used for the measurement should not be affected by the physical environment. It should be available easily. Thus, to make any device for the measurement of physical quantity, above criteria should be kept in mind.
