Feedback in general is the process in which changing one quantity changes a second quantity, and the change in the second quantity in turn changes the first.Positive feedback amplifies the change in the first quantity while negative feedback reduces it.....
A linear relationship
it is a proportional relationship because a proportional relationship is known as a relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
It is a measure of the extent to which a linear change in one quantity is accompanied by a linear change in the other quantity. Note that only linear changes are measured and that there is no causality.
A bar graph.
This is the definition of rate. It describes how one quantity relates to another as a ratio: meters per second, miles per hour, dollars per gallon. for example
It is a quantity that is not affected by other quantities. It may or may not affect them.
Derived quantities are quantities which are made or found from other major quantities. There are two types of quantities. Ones are which are recognized throughout the world and using them other quantities are made.
A fundamental quantity is a physical quantity that is independent and not defined in terms of other physical quantities. These fundamental quantities form the basis for the measurement of other physical quantities. Examples of fundamental quantities include mass, length, time, and electric charge.
Fundamental quantities are quantities that can be measured such as mass, length and temperature. Derived quantities are quantities that has to be calculated such as pressure, volume and work done.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.
If two quantities are directly proportional, when one quantity increases by 10 percent, the other quantity will also increase by 10 percent. This means that the relationship between the two quantities remains consistent as they change by the same proportion.
It is called direct variation.
When one quantity is proportional to another, it indicates that one quantity is dependent on the other by a factor and increases/decreases with the other quantity. When the two quantities are equal, the output of both the quantities is said to be the same.
A linear relationship
A fundamental quantity is a physical quantity that cannot be defined in terms of other physical quantities, while a derived quantity is a physical quantity that is defined in terms of fundamental quantities through mathematical relationships. Examples of fundamental quantities include mass, length, and time, while examples of derived quantities include velocity, acceleration, and energy.

Electric current is considered a base quantity because it is an independent physical quantity that cannot be defined in terms of other fundamental quantities. It is a fundamental building block in physics and is used to define other electrical quantities such as voltage and resistance.
