Question

Mention Fundamental quantities Give their units along
with symbals. What are derived units Explain with example​

Answer 1

In physics, there are seven fundamental physical quantities that are measured in base or physical fundamental units: length, mass, time, electric current temperature, amount of substance, and luminous intensity. ... All other units are made by mathematically combining the fundamental units. These are called derived units.

Units of measurement derived from the mathematical combination of SI base units are called SI-derived units. For example, the ratio of the SI unit for distance (meter; m) and the SI unit for time (second; s) gives the SI-derived unit for speed (meter per second; m/s).
