the same as the base unit OF time.
Base units need not have ANY volume. A second is the base unit for measuring time and it has no volume!
derived units come from basic units such as length, time, electrical current.AnswerIn SI, Derived Units are any units that are not Base Units. There are seven Base Units, from which all Derived Units are formed. For example, a coulomb (derived unit) is equal to an ampere second (both Base Units).
The base unit of time is the second.
For length Meter and for time Second.
In the SI, it is DEFINED as a base unit, together with the unit of length, the unit of time, and a few others. Other units are derived from these base units.
no, but i sure as can imagine a system of base units in which "amount of substance", "thermodynamic temperature", and "luminous intensity" are not included (they can be derived from the base units) and one where electic charge replaces electric current as a base unit.
The SI, or metric, system is devided into two sets of units; base units and derived units. The base units are used to define all other units. There are seven base units. metre, m. length. kilogram, kg, mass. second, s, time. ampere, A, electrical current. kelvin,K, temperature. candela, cd, luminous intensity. mole, mol, amount of substance.

Derived units are simply more complex because they are made up of several (that is, usually, by more than one) base unit. It is just the way they are defined; for example, in the SI, distance and time are base units, while speed is a derived unit (distance / time). You can just as well invent a system of units where - for example - time and speed are base units; in this case, distance would be a derived unit.
The area of a triangle is half base times height so any triangles whose base times height is 60 units will have an area of 30 square units e.g. base = 10 units, height = 6 units; base = 5 units, height = 12 units; base = 7.5 units, height = 8 units.
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
suplementary units are dimendionless and are not derived from other (base) units while derived units are derived from base units and they do have dimionsions.
