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).
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.
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'.
