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.....

What is the relationship between two quantities in which the ratio of one quantity to the other quantity is constant?
A linear relationship
When a rate of change varies from point to point the relationship is what?
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.
What is the correlation between two quantities?
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.
How is a rate a measure of one quantity per unit of another quantity?
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
Which graph shows quantities and how they vary by other factors?
A bar graph.
What is an independent quantity in math?
It is a quantity that is not affected by other quantities. It may or may not affect them.
What is derived quantity?
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.
What is a foundamental quantity?
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.
What are derived quantities what are the fundamental quantities?
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 what does the other do?
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.
What is the quantity of two quantities in which the ratio of one quantitie to the other quantity is constant?
It is called direct variation.
What is the difference between saying that one quantity is proportional to another and saying it is equal to another?
When two quantities are proportional, it means that they change in a consistent ratio. If one quantity is equal to another, it means that they have the same value. Proportional relationships involve a constant factor, while equal relationships involve identical values.
What is the relationship between two quantities in which the ratio of one quantity to the other quantity is constant?
A linear relationship
What is the difference between a fundamental and derived quantity?
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.
When a rate of change varies from point to point the relationship is what?
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.
What is a relationship between two quantities in which the ratio of one quantity to other quantity is constant?
It is called direct variation.
Why is the electric current a base quantity?
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.
