What is the difference between a base unit from a derived unit?
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
Are dogs more complex than humans?
Considering senses, dogs are more complex, dogs have 6 senses, whereas humans av 5.
How many units of alchol can a women have a week?
1 4 units for woman in aweek is the recommended amount according to the bbc news website
Are older fossils more complex?
no because older fossile are more primitive animals.
Can you have more than one variable in an experiment?
Yes you can, but the more variables you have the more complex the problem becomes.
Why are derived units more complex than fundamental units and why is it important to know whether a unit is derived or fundamental?
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.
Mention differences between fundamental and derived units?
The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.
Why are there 7 fundamental physical quantities and not more?
If you look at the definitions of the SI units, and especially the derived units, you'll see that all the derived units are derived from other units. It might actually be possible to have even less base units, but that would make the system of units unnecessarily confusing.
What is the Difference between derived quantity and fundamental quantity?
The quantity which has only direction is called fundamental quantity.Example-Direct current.The quantity which has both magnitude and direction is called derived quantity.Example-Altranating current.
What are fundamental units?
Fundamental unitsFundamental units, or base units, are those that cannot be decomposed into more basic units. (Note that "basic" does not mean "smaller.") Derived units, on the other hand, are those that are defined in terms of other units, which may be base units or other derived units. In the SI system, the base unit of length is the meter, the base unit of mass is the kilogram, and the base unit of time is the second. The base unit of electrical current is the ampere which is defined in terms of the force between parallel, current-carrying conductors.One of a set of unrelated units of measurement, which are arbitrarily defined and from which other units are derived. For example, in the SI system the fundamental units are the meter, kilogram, and second.
What is a derived unit?
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).
What is different of derived and fundamental quantities?
Fundamental quantities are such things as the kilogram ( a physical mass of metal), the Metre (now defined by reference to atomic oscillations).[In detail, metre, second, kg, mole, Kelvin, candela.]Derived quantities are such things as the force due to gravity, acceleration, and more obvious ones such as ml, cm, and so on.AnswerThe SI does not define 'fundamental quantity', instead it uses the term 'Base Unit'. All other units are 'Derived Units', so-called because they are each derived from combinations of Base 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 is difference between base quantity and derived quantity?
Base quantities (Scalar Quantities) :Independent quantities who have single standard units.- time /seconds-distance/metersDerived Quantities (Vector Quantities):Quantities derived by multiplying or dividing 2 base quantities.- Velocity = distance/timeunit of Velocity = m/s

Is a cubic meter a SI unit?
m can mean milli or 10-3 and as such is a multiplier not a unit m = mass (kg) or other is a fundamental and not a derived unit M = moles is a fundamental unit m = meter is a fundamental unit and not derived
A unit of measure made of a combination of two or more base units is called?
derived
