What is the ratio between two different quantities?

The ratio between two different quantities is the rate . When expressed in words, "per" separates the two measurements described; for example, miles per gallon, feet per second.

What is the difference between supply and quantity supplied?

Supply is the amount of a product offered for sale at all possible prices that can succeed in a market; while quantity supplied is the amount that producers are willing and able to supply are a certain price.

What is ratio between two different quantities?

A ratio is basically a comparison of two different quantities to each other. You often find ratios in their simplest form. For example, if, in one container, you had 500ml of water and in another you had 1000ml, this is a ration of 500 to 1000 which is written as 500:1000 . However, t ( Full Answer )

What is the difference between a vector and a scalar quantity?

Vectors are quantities that have a size and a direction. Examples: Displacement, velocity, acceleration, momentum, force. Scalars are quantities that have a size but no direction. Examples: Temperature, cost, speed, length, height, width, age,energy. = Scalar quantities have only magnitude. Vect ( Full Answer )

What is the difference between a change in demand and a change in quantity demanded?

In economics, demand is defined as the quantity of a good or service consumers are willing and able to buy at a range of prices . A change in demand occurs when a demand factor/condition changes. The four main demand factors are: . Consumer tastes, fashions and preferences. . Consumer inc ( Full Answer )

Differences between Demand and quantity demand?

Demand refers to the entire relationship between the prices and thequality of the product. Quality demand refers to one particularpoint on the demand curve.

What is the difference between derived quantities and fundamental quantities?

In the SI system , there are two categories of unit: the Base Unit and the Derived Unit . There is no such category as 'fundamental unit'. There are seven Base Units. These are: the metre, kilogram, second, ampere, kelvin, candela, and mole. All other units are Derived Units, and these a ( Full Answer )

What is the difference between fundamental and derived quantities?

Fundamental units cannot be derived right from any other one. kilogram in no way is connected to second or metre or kelvin. But derived is the one which has been got right from thefundamentals. ex: density has unit kg / m^3 Here fundamental kg and m have been used. Fundamental units are seven in num ( Full Answer )

What is the difference between unit of measure and quantity?

Difference between vector and scalar quantity?

A vector is a quantity with a direction that matters, like force, velocity, acceleration, etc. A scalar is a quantity with no direction, like temperature, cost, mass, etc.

What are Physical quantities?

They are properties that you can measure and be verified by another party. Usually, standards are available to eliminate any difference in measurement methods and definitions. For example, we can measure length, speed, weight, humidity, temperature, and time, with certainty. Those are physical quant ( Full Answer )

The differences between scalar quantities and vector quantities?

A scalar quantity is just a number e.g. 3 miles A vector quantity is a number with directions e.g. 3 miles south So the difference between them is that vector has a particular direction to go with but a scalar quantity is just a number.

What is the difference between vector and scalor quantity?

Vectors include information about their direction, and are incomplete without it. Examples are displacement, velocity, acceleration, momentum, magnetic field. (Velocity is speed with direction.) Scalars are complete without stating any direction. Examples are temperature, cost, mass, speed. ( ( Full Answer )

What is the difference between physics and applied physics?

Physics is an umbrella term, while applied physics is a sub-category of physics. Some other sub-categories are... Theoretical Physics Astrophysics Partical Physics Applied Physics is one of the most common though least glammerous types of physics, since it involves more real world applications. ( Full Answer )

Ratio between two different quantities?

A ratio between two quantities, usually with differing units, is called the rate . When describing the units of a rate, "per" usually separates them. For instance: beats per minute, miles per hour, gallons per mile.

What is the fundamental differences between demand and quantity?

demand = how much people want it quantity (supply) = how much you have/can sell When the demand drops, the supply increases, and when the supply increases, the demand drops, but it will turn around again, and when the supply is low, the demand increases, and when the demand increases, and the supply ( Full Answer )

What is difference between base quantity and derived quantity?
