Answer 2

Answer:

Which of the following is a fundamental unit?​

Explanation:

• What are fundamental units-  fundamental units are base units of measurement of base quantity.
• In this SI system there are in all seven fundamental units- kilograms, meter, candela, second, ampere, kelvin and mole.
• This SI units have some symbols.
• Meter is used for length, second is used for time, kilograms is used for weight, ampere is used for current, kelvin is used for temperature, mole is used for amount of substance, candela is used for luminous intensity.
• Fundamental units can not be derived from another unit.
• It cannot be relate to other fundamental quantity.
• This SI units are used over the world.

Hence, kilograms, meter, candela, second, ampere, kelvin and mole are seven base fundamental units.
