What is meant by unit of a physical quantity?
A unit of a physical quantity is a standardized quantity used to express measurements. These units help provide a clear and consistent way to quantify different physical properties such as length, mass, time, and temperature. Units allow for effective communication and comparison of measurements across different contexts.
What is meant by unit of a physical quantity in physics?
The unit of a physical quantity in physics is a standardized way to express and measure that quantity. Units give the quantity a numerical value and specify the scale at which it is being measured. Units are essential for consistency and clarity when communicating about physical quantities.
What are the quantity unit pair?
Quantity unit pairs refer to the combination of a numerical quantity and its corresponding unit of measurement. For example, 5 meters, 10 kilograms, or 20 seconds are all quantity unit pairs. They are used to express measurements in a standardized and clear way.
What is the quantity that expresses magnitude but does not express direction is called a?
Scalar.
What is the difference between ppt and ppm?
Parts per thousand (ppt) is a unit of measurement used to express a very small amount of a substance in a larger sample. Parts per million (ppm) is another unit of measurement that is even smaller than ppt, used to express an even smaller quantity of a substance in a larger sample. Essentially, ppm is 1000 times smaller than ppt.

What the standard unit used to express a quantity of charges?
The unit of measurement for the quantity of an electrical charge is called an electrometer. The quantity of charge can also be measured in directly by a ballistic galvanmotere.

What measurement used to express kilograms?
Kilograms are used to express the metric measurement of mass.
Is heart quantitative or qualitative?
Heart rate is generally a quantitative measurement. You can give a specific number (quantity) for it. You could express heart rate as a qualitative measurement by simply using comparative phrases such as fast, faster, slow slower, dangerously high, dangerously low, etc. Often the quantitative measurement is mapped to the qualitative terms to give a quantitative range that can map to a qualitative term to express the impact of that type of heart rate.

The process of dividing a nominal quantity by a price index in order to express the quantity in real terms is called?
Deflating!

What is a proper unit?
A proper unit is a unit of measurement that is commonly accepted within a specific system of measurement, such as meters in the metric system or pounds in the imperial system. Proper units are used to quantify and express physical quantities accurately and consistently.
