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.
Median.
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.
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.
A linear relationship
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.
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 called direct variation.
You multiply or divide the first quantity by the number and then you do the same for the other quantity.
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
Fundamental quantities r those which r independent of other quantities and r scaler and on the other hand derived quantities r those which depends on fundamental quantities!! For example metre sqaure!
a change in supply is the shift in supply curve due to change in price of other commodities and other factors like taste,weather,income e.t.c while a change in quantity supply is the change in price of the commodity itself that affect the quantity supply,here the supply curve remain constant but there will be a movement along the supply curve.
