The ratio between two different quantities is the rate . Usually, the second unit is a measure of time.
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.
Kinematic is the branch of physicis that deal with the description of motion but Dynamics is the branch of physicis that deal with the causes of motion.
quantity is amount quality is the condition or value of something in my opinion quality is better than quantity
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.
A unit is the basis of a measurement and the quantity would be howmany of those units there are.
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…o make this clearer, we can simplify the ratio. Seeing as 500 is half of 1000 we can simplify it to a ratio of 1:2 because 1 is obviously half as big as 2! A ratio, quite simply, compares the amount of something to another amount. So in this case, there is 500ml of water in one container for every 1000ml of water in the other container. Ratio is a mathematical comparison of the amount of something. Hope this helps! ( Full Answer )
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…or quantities have bothmagnitude and direction. Temperature and volume are scalar becausethey don't have a particular direction. Velocity and Force (because acceleration actually has a direction)are vector quantities. Velocity is the combination of the scalar quantity of speed with adirection for that speed. Speed is always a positive number butvelocity can be negative and positive because it has a direction.

Demand is the total amount of demand at all possible prices; while quantity demanded is the demand at a particular price.
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…ome. . The price of substitute goods. . The price of complimentary goods. A change in demand is shown visually as a shift of a demand curve. Quantity demanded is defined as the quantity of a good or service consumers are willing and able to buy at a price . A change in quantity demanded is caused only by a change in price. The law of demand states that as the price of a good or service increases (ceteris paribus), the quantity demanded will decrease (and vice versa) . A change in quantity demanded is shown visually as a movement along a demand curve. . Ceteris paribus is a Latin term; it is used in economics to signify that all demand/supply factors remain unchanged. A change in Demand is affected by either a change in productivity or a change in the price of a certain product. And a change in the quantity demanded is affected by either immigration( a large increase in the quantity or laborers) and an shift in minimum wage. Change in quantity demanded as illustrated in a demand curve is the movement along the curve or the response in quantity demanded due to a change in price. Change in demand as illustrated in a demand curve in the movement OF the curve or the expansion or contraction of the demand. (e.g. more consumers in the market) Demand: the people's desire to purchase something. For example, when the Apple Ipod came out, it was in high demand so the suppliers had to make more of them quickly because they were running out and were wanted by the people Quantity: A particular or indefinite amount of something. For exmaple, 2 fish are swimming the the lake. The ocean has a vast amount of water change of demand means increase or decrease in demand due to change in the price of the commodity other than other factors that affect demand.but however change in quantity damand means increase or decrease in demand due to change in factors that affect demand apart from the price of the commodity. A change(shift) in demand refers to a change in the amount of a product or service demamded in regards to changes in expectations,income,demographics,substitutes and expectations and will cause a "shift" in the demand curve. A change in quantity demanded refers to a change of the inputs(resources required to produce that good or service) required to produce the goods or services being demanded. If the price of producing the good or service changes then the quantity demamded will "change" causing a movement along the demand curve. ( Full Answer )
The quantity which has only direction is called fundamental quantity.Example-Direct current.The quantity which has both magnitude and direction is called derived quantity.Example-Altranating current.
Demand refers to the entire relationship between the prices and thequality of the product. Quality demand refers to one particularpoint on the demand curve.
A scalar has only size (amount, or quantity), example: a volume of liquid. A vector requires additionally a direction to define it ,examples: velocity, force.
Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. vectors need bold letters to show them.
Quantity is how much of something that you have. Quality is how long something lasts or how "good" it is.
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…re combinations of Base Units, sometimes given special names. For example, the coulomb is a Derived Unit, and is equivalent to an ampere second, which are both Base Units.. ( Full Answer )
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…ber along with two supplementary. They are kg, m, s, K, Cd, A, mol. Supplementary are rad, Sr. But derived are innumerable. Comment SI doesn't use the term, 'fundamental'. Those units listed aboveare termed 'base' units. 'Supplementary' units are no longerused.. ( Full Answer )

Increase in demand:: It imply rightwaed shift of demand curve. Therefore change in factors other than price. 1. increase in taste increase in demand curve 2. increase in popoulation increase in demand curve 3. increase in income increase demand if normal good 4. fall in income increase demand if an… inferior good 5. increase in price of substitute (pepsi) increase demand for good(coke) 6. fall in price of complement (beer) increase demand for good 7. if we expect the price of the product to increase in the future , our demand today will increase. Increse in quantity demanded:: Movement up the demand curve. Therefore change in price-------- increase in price cause a decrese in quantity demanded, decrese in price cause an increase in quantity demanded . ( Full Answer )
a vector quantity is one which has a magnitude and a diretion.Eg: velocity,displacement,force,weight . A scalar quantity is one which has magnitude but no direction.Eg:tmie mass distance
Vector quantities are those which have both magnitude and direction while scalers quantities have only magnitude or numerical value but no direction.
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.
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…ities. Contrarily, we cannot measure inflation rate, hunger, pain, etc. with certainty. In short they are quantities that can be measured. ( Full Answer )
The difference between demand and quantity demanded is in the definition of them. Demand is the amount of demand at all possible prices; while quantity demanded is the amount of demand at a particular price.
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.
Which quantity helps you better understand the relationships between bond type and physical characteristics electronegativity difference or percent ionic character?
The quainty of this helps because it deals with different scales and most people find the pauling scale to be the easy. the electronegativity kind of help me understand it because the way you have to calculate it and the different scales they use. I found the pauling scale to be easy.

Quantum physics is an area of physics that focuses mainly on the properties and behaviour of sub-atomic particles. Physics in general can be the study of anything from the life cycle of a star to the effects of gravitational fields.
Basic or fundamental quantities are seven in number. They cannot be derived right from one another. Hence they are independent. They are length, mass, time, electric current, temperature, quantity of substance, luminosity. Two sub are there. They are plane angle and solid angle. But derived are many… in number. Just by the name they are derived right from the fundamental. They are area, volume, velocity, acceleration, force, momentum, magnetic induction, electric field, dipole moment, pressure, density etc etc ( Full Answer )
Change in demand is subjective, it could be increase or decrease in the qauntity of good or services asked for, while change in quantity demand is objective, it refers to actual quantity/amount of good or seevices requested /demanded .
A physical property of a material is an intrinsic characteristic ofthis material; examples: density, hardness, refractive index,boiling point etc. This not depends on the material mass. The physical quantity is a measure of the property; examples:g/cm 3 , volt, pascal, coulomb etc.
The physical property is measured by physical quantities. Examples: a mass is measured in kg, the thermal conductivity ismeasured by W/m.K, the density is measured by g/cm 3 .
The terms mass, and quantity of matter, are synonymous. The difference is that mass has only one syllable and quantity of matter has six.
There are several reasons. Measurement units evolved over time. People used different units across countries over time. Even now, you have the Imperial system that has been mostly abandoned by developed countries across the world. But USA, Burma, Liberia and a few Caribbean islands still use the Im…perial system (or a variant). Differences in scale: It would make little sense to measure the distance between two cities in metres, or the size of an ant. In the first case you would use a kilometre, in the second a millimetre. Sometimes the way in which a physical measure is derived will affect its units. Energy can be defined as the ability to do work and so the unit is the same as the unit for work: a Joule. However, thermal energy is defined as the amount of heat required to raise the temperature of 1 gram of pure water by 1 kelvin and in 1 calorie. ( Full Answer )
