What is measured in metric units?
In the SI system, there are 7 basic units. These are kilogram (mass) meter (distance) second (time) ampere (electric current) kelvin temperature) mole (amount of chemical substance) candela (luminous intensity). There are also derived SI units for other measurements such as meters per second (for speed).
What are the derive of quantities?
The derivative of a quantity represents the rate at which that quantity is changing with respect to another variable, typically time or distance. It is a fundamental concept in calculus and is denoted by the symbol dy/dx, where y is the dependent variable and x is the independent variable. The derivative provides important information about the behavior of a function at a specific point, such as its slope or instantaneous rate of change.
Why is a cubic centimeter a derived unit?
The basic unit is meter. Centimeter and the cubic value are derived from the basic meter.AnswerIt isn't. It's a submultiple of a 'base unit'.
What are the examples of basic quantity?
Length. mass. time (physics)
What are all the measures?
Basic units are: Length meter m mass (weight) kilogram kg time second s electric current amp aTemperature Celsius C or Kelvin K Amount of substance mole mol Luminous intensity candela CD there are many other derived units. seehttp://lamar.colostate.edu/~hillger/basic.htm
How many derived quantity were there name them?
There are seven derived quantities in the International System of Units (SI): frequency, force, pressure, energy, power, electric charge, and electric potential.
Why is area called derived quantity?
An area, in its simplest form is derived by multiplying together two lots of the basic quantities - lengths.
What is the basic unit of electric current?
The basic unit of electric current is the ampere (A). It is defined as the flow of one coulomb of electric charge per second.
What basic unit of electric current?
The basic unit of electric current is the ampere (A), which represents the flow of electric charge through a given point in a circuit per unit of time.
Why current is not derived quantity?
That's because that's the way the scientists who created the SI defined it to be. In the relationship: charge = current x time It is possible to derive any of the three quantities from the other two (the other two would then have to be defined as base quantities). The reason it was defined this way is probably because it was found to be easier to measure a current accurately, than to measre a charge.
What is the Basic Three Electrical Quantities?
The basic three electrical quantities are voltage (V), current (I), and resistance (R). Voltage is the electrical force that moves an electric charge. Current is the flow of electric charge. Resistance is the opposition to the flow of electric current.
What is the basic types of physical quantities in chenistry?
Some of the basic types of physical quantities in chemistry include temperature, mass, quantity, length, and time. Some other physical quantities are amount of substance, electric current, and luminous intensity.
What is the basic unit of electric crrent?
Current is measured in amps
What is the ampere a unit of?
Ampere is the basic unit of electrical current.AnswerThere are, in fact, two answers. The ampere is the SI Base Unit for electric current, but it is also the SI Derived Unit for magnetomotive force.
Why charge is not a basic quantity?
Because charges may be of two kinds i.e. positive and negative. And base quantities never have different kinds but are only of one kinds i.e. length, mass,time etc. That's why charges' are expressed in the dimensions of current and Time and not carry there own dimension.

Is the unit of speed a basic unit or a derived unit?
It is a derived unit. It measure distance traveled per unit of time. For example meter per second or m/s. Speed or velocity as it is sometimes called is derived from the units for distance and time.
What are the differentiate between the basic quantities from derived quantities?
Basic quantities are quantities which can be arrived at without performing any mathematical procedure. Derived quantities are those which can be arrived at only after performing mathematical procedure.
