Quantity is a characteristic of objects and phenomena defined by multitude and magnitude. Multitude answers the question of how many and pertains to discrete objects in a given collection. Counting and ordering are the determining factors of multitude. Magnitude answers the question of how much and pertains to the properties of objects and phenomena in the real world. Measurement is the determining factor of magnitude and is based on infinitely divisible quantities along a continuum.
A vector.
Equilibrium is defined to the price-quantity pair where the quantity demanded is equal to the quantity supplied, represented by the intersection of the demand and supply curves.
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
density is defined as the quantity in mass upon quantity in volume Mass/volume= density
No, power is not a vector quantity. It is a scalar quantity because it only has magnitude, not direction. Power is defined as the rate at which work is done or energy is transferred.
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.
Density
a variable can be defined as a quantity in an equation which explains the behaviour of the given function
Why? Because that's the way speed and velocity are defined.
The quantity of arithmetic cannot be measured and so the density is not defined.
It is Price Elasticity of Supply. It is defined as the ratio of a percentage change in quantity supplied to the percentage change in price (which brought about the change in quantity supplied).
It is Price Elasticity of Supply. It is defined as the ratio of a percentage change in quantity supplied to the percentage change in price (which brought about the change in quantity supplied).
