Fundamental Quantities in SI Units

Fundamental quantities are basic physical quantities in the International System of Units (SI) that cannot be derived from other quantities.
Examples include length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

SI Unit for Electric Current

The correct SI unit for measuring electric current is the ampere (A).
The ampere is defined as the amount of electric charge passing a point in an electric circuit per unit time.

SI Unit for Temperature

The correct SI unit for measuring temperature is the kelvin (K).
The kelvin is the SI base unit of temperature and is one of the key quantities in thermodynamics.

Mathematical Concepts: Rate of Change

The mathematical concept that deals with the rate of change of a function is calculus.
Specifically, derivatives in calculus provide a method to determine how a function changes as its input changes.

Set of Integers

A set of numbers that includes both positive and negative whole numbers, as well as zero, is known as the set of integers.
This set is commonly denoted as ℤ, which includes {..., -3, -2, -1, 0, 1, 2, 3, ...}.

Mathematical Object: Matrix

A matrix represents a mathematical object consisting of a rectangular array of numbers or symbols.
Matrices are used for various applications, including solving systems of equations, transformations, and more in linear algebra.
