Question

state 7 fundamental quantity with their SI units ? ​

Answer 1

Answer:

The value of a physical quantity is usually expressed as the product of a number and a unit. The unit represents a specific example or prototype of the quantity concerned, which is used as a point of reference. The number represents the ratio of the value of the quantity to the unit. In the case of the kilogram, the prototype is a platinum-iridium cylinder held under tightly controlled conditions in a vault at the BIPM, although there are a number of identical copies kept under identical conditions located throughout the world. A quantity of two kilograms (2 kg) would have exactly twice the mass of the prototype or one of its copies. There are seven base quantities used in the International System of Units. The seven base quantities and their corresponding units are:

length (metre)

mass (kilogram)

time (second)

electric current (ampere)

thermodynamic temperature (kelvin)

amount of substance (mole)

luminous intensity (candela)
