A measure of how much one economic variable responds to changes in another economic variable. Click again to see term 👆 1/99 THIS SET IS OFTEN IN FOLDERS WITH The price elasticity of demand (PED) is a measure of how much the quantity demanded changes with a change in price. The PED for a given good is determined by one or a combination of the following factors: Availability of substitute goods: The more possible substitutes there are for a given good or service, the greater the elasticity. When several close substitutes are available, consumers can easily switch from one good to another even if there is only a small change in price.

The scalar physical quantity is the physical quantity that has magnitude only and has no direction, to describe the scalar physical quantity, It is enough to know its magnitude only by giving its numeric and its measuring unit, such as we say the body mass equals 10 kilograms. The age-old way we measure time and distance is changing. the speed of light in a vacuum—and from now on fix its numerical value at our best-measured value, without uncertainty.

What does MEASURED QUANTITY mean? To express any measured quantity, one should know the following: (a) The unit in which that quantity is measured, (b) The numerical value of the measure. The numerical value gives the number of times the unit is contained in the quantity.
