Question

define the term unit .which are fundamental units

Answer 1

hi there✋✋✋✋


units are standards for measurement of physical quantities that need clear definitions to be useful. Reproducibility of experimental results is central to the scientific method. A standard system of units facilitates this.


The SI units for the seven fundamental measurable qualities are:

1)A , ampere, a unit of electrical current.

2)cd , candela, a unit of luminous intensity.

3)K , kelvin, a unit of absolute temperature.

4)kg , kilogram, a unit of mass.

5)m , meter, a unit of distance.

6)mol , mole, a unit of quantity/counting.

7)s , second, a unit of time.

Heyaa.... Unit is a fixed amount or number used as a standard of measurement....  Now , A fundamental unit a unit of measurement for a measurable physical property from which every other unit for that quantity can be derived. The fundamental unit for a particular measurable quantity is chosen by convention. They are the units of the fundamental dimensions of physics. For example fundamental unit if length is metre ,time is second , mass is kilogram , current is ampere etc .  ✌️✌️✌️ Aryan khanna
