What else can I help you with?
Is coulomb an S I base unit?
No, a coulomb is a derived unit. A base unit is a unit that isn't made by combining other units. There are seven base units, including metre (length), kilogram (mass), and second (time). Coulomb is the unit of electric charge. One coulomb is the charge delivered by a steady current one ampere in one second. It is derived from the base units ampere (electric current) and second (time).
How many units are in the SI system and can i see them?
The SI has 7 base units: http://en.wikipedia.org/wiki/SI_base_unit Also, the SI has tens of derived units - perhaps hundreds of them, since you can combine the base units in many ways. Those units are ultimately derived from the 7 base units. For example, units for area, volume, speed, force, energy, pressure, electric charge, voltage, and many more, are derived from some of the base units. http://en.wikipedia.org/wiki/SI_derived_unit
How do derived units differ from base unites?
Seven metric base units make up the foundation of SI. And Specific combinations of SI base units yield derived units. That's why the differ.
What happen when time was not included in system of 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.
What is the base unit of measure for the metric system?
the international system of units or SI units have 7 base units for the measurement of different types of quantities. it uses the following units: meter - length kilogram - mass second - time kelvin - temperature ampere - current candela - luminous intensity mole - amount of substance

What are the units of measurement for electric charge in the International System of Units, commonly known as coulombs?
The units of measurement for electric charge in the International System of Units are coulombs.
Differentiate derived units from supplementary units?
Derived units are units formed by combining base units through mathematical operations, such as area (square meters). Supplementary units are units used alongside base units to form the complete set of units in a system, such as the radian for angles in the International System of Units.
What is the charge in units of the electronic charge of an electron?
The unit of charge is coulombs
List three sets of base and height measurements for triangles with areas of 30 square units?
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.
Why current a fundamental quantity though it is flow of charge per unit time?
Ampere = Coloumb / second is the same as saying that Coloumb = Ampere x second. Any of the two electrical units can be derived from the other one. Ampere is NOT a "fundamental quantity"; it is an SI base unit. The base units are not necessarily those that are somehow considered more "fundamental" than others; instead, the base units are those that can be measured with a great accuracy. In the case of current vs. charge, it seems that measuring a current can be done with greater accuracy than measuring a charge directly; therefore, the current is the base unit, and the current is derived. However, this doesn't make current any more "fundamental" than charge.
What are the 3 main base units?
the 3 main base units would be, > ?
What the measurement of units?
The SI has seven base units (kilogram, meter, second, ampere, kelvin, mole, candela), and lots of derived units - for example, meter/second for speed/velocity, coulomb = ampere x second for electrical charge, etc.
A triangle has a base of length 20 units and perimeter of 66 units. If a similar triangle has a base of 15 units what is its perimeter?
49.5 units
What derived units?
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).
Derived units are combinations of?
base units
