Constant
The rate of change refers to how a quantity changes in relation to another quantity, typically expressed as a ratio. It is often represented as a value, indicating the change per unit of the independent variable. However, the absolute value of a rate of change can be considered to focus solely on the magnitude of the change without regard to direction. Thus, while the rate of change itself is a value, its absolute value can also be relevant in specific contexts.
a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
The part of a math sentence whose value is always the same and is represented by a numeral is called a "constant." Constants are fixed values that do not change, such as numbers like 5, -3, or π. In contrast to variables, which can represent different values, constants provide a specific quantity in mathematical expressions and equations.
By two amounts of change I assume mean absolute amounts. Assume the following: Quantity 1 begins at 6 and changes to 3. The absolute value of the change is 3 and the percent change is 50% Quantity 2 begins at 30 and changes to 27. The absolute value of the change is 3 and the percent change is 10%
An unknown changeable quantity refers to a variable in mathematics or science whose value is not fixed and can vary or change under different conditions. It is often represented by symbols, such as ( x ) or ( y ), in equations or expressions. This concept is crucial for understanding relationships and functions, as it allows for the exploration of how different factors influence outcomes.
Yes. Although it can also be used for constants whose value is not yet known.
A variable

the output of a function; a variable whose value depends on the value of the input.

Comparator is usually a substance which compares two quantities; one quantity is the processed one and the other is a standard value to which the processed value has to be compared. Hysteresis is a property in which the change in the magnetization lags behind change in the magnetic field. Now, Hysteresis comparator can be described as a comparator which compares a processed quantity with a quantity whose value is standard for hysteresis property., the difference being given as the output
No, the magnitude of a quantity does not change with a change in the system of units. The numerical value representing the quantity may change based on the system of units used, but the magnitude itself remains constant.
no.

It means 5 multiplied by M. M is a variable, meaning a quantity whose value is not known.
A variable is a quantity which changes its value through out the program or its lifetime. But a constant is a quantity which does not change its value through out its life time. There are 5 basic constants.
a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
