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
Standard use of measurement used by scientist?
There are 7 SI units (Systeme International d'Units) from which all other measurements are derived. These are: Length (metre) Mass (kilogram) Time (second) Temperature Interval (Kelvin) Electric Current (ampere) Amount of Substance (mole) Luminous Intensity (caldela) All other units aere derived from combinations of these 7 base units
Are older fossils more complex?
no because older fossile are more primitive animals.
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 combinations of fundamental units and are more complex because they represent physical quantities that are derived from basic quantities. It is important to know whether a unit is derived or fundamental because derived units are dependent on fundamental units and understanding this relationship is crucial for accurately interpreting and applying equations in various scientific and engineering fields.
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 length is fundamental unit?
Length is considered a fundamental unit because it is a basic physical quantity that cannot be derived from other physical quantities. It serves as a building block for other derived units and is essential for defining more complex physical concepts. As such, length is a fundamental aspect of measurement systems and forms the basis for our understanding of space in the physical world.
Why are there 7 fundamental physical quantities and not more?
The 7 fundamental physical quantities were chosen because they are considered independent and cannot be derived from other physical quantities. These 7 quantities (length, mass, time, electric current, temperature, amount of substance, and luminous intensity) form the basis for all other physical measurements in the International System of Units (SI). Additional fundamental quantities can be derived from these 7, making them sufficient for describing physical phenomena comprehensively.
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 is a derived unit?
A derived unit is a unit of measurement that is created by combining base units through multiplication or division. It is used to express physical quantities that are derived from fundamental physical quantities. Examples of derived units include the newton (N) for force and the joule (J) for energy.
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.
How do you describe derived units?
Derived units are made by combining base units using mathematical operations such as multiplication and division. They are used to express physical quantities and their combination is necessary to represent more complex measurements, such as velocity or volume. Examples of derived units include meters per second for velocity or cubic meters for volume.
What are fundamental units?
Fundamental units are the basic units of measurement in a system of units, typically defined independently of other units. In the International System of Units (SI), the fundamental units include the meter for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity. These units form the basis for deriving all other units of measurement.
Why is pressure a derived quantity?
Pressure is considered a derived quantity because it is calculated from fundamental quantities (force and area). Pressure is defined as force per unit area, so it cannot be measured directly but is derived from other measurements.
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.
