the force exerted by a colomn of air is
This is called equilibrium.
A change in quantity demanded
A change in quantity demanded
Elastic
perfectly elastic demand the quantity change by infinitely large amount proportion due to the small change in price, is called perfectly elastic demand. perfectly inelastic demand the quantity demand doesn't change at all due to the change in price is called perfectly inelastic demand. relatively elastic demand the quantity demand changes by a little more percentage than the change in price is called relatively elastic demand. relatively inelastic demand the percentage change in quantity demand is less than the percentage change change in its price is called relatively inelastic demand unitary elastic demand the percentage change in quantity demand is equal to the percentage change in price is called unitary elastic demand
This is called equilibrium.
It is called a variable.
A change in quantity demanded
It means that there is a quantity called momentum; the total quantity of which doesn't change.
It is called a variable.

They take the place of an unknown quantity. They can change values, thus they are called variables, their quantity varies.
change of any quantity divided by its original quantity
a change in quantity supplied is the result of
Cross-price elasticity.
