What are the advantages of estimating size or magnitude of physical quantity before it is measured?

So that you can immediately spot an outlandish, bogus, unreasonable result of the
measurement if that happens, and repeat the measurement. In other words, to
guard against the dreaded Curse of the Calculator . . . blindly accepting whatever
appears before you, without question, and looking foolish when you report it.

What is the difference between physical property and physical quantity?
The physical property is measured by physical quantities. Examples: a mass is measured in kg, the thermal conductivity is measured by W/m.K, the density is measured by g/cm3.
A physical quantity described by both magnitude and direction is called what?
A physical quantity that is specified by both magnitude and direction is a vector by definition.
What two components do physical values have in the real world magnitude and?
direction
What is a quantity that can be measured?
Physical quantities are quantities that can be measured. For example: water, distance, etc.
What physical quantity is measured in Torr?
pressure
What is the difference between physical property and physical quantity?
The physical property is measured by physical quantities. Examples: a mass is measured in kg, the thermal conductivity is measured by W/m.K, the density is measured by g/cm3.
Which magnitude gives the most information about the physical nature of a star?
absolute bolometric magnitude
A physical quantity that has both magnitude and directions is?
Such a physical quantity is a vector.
What physical quantity has a direction but no magnitude?
scalar
Why is velocity a vector quantity and speed is a scalar quantity?
Because it is: * A property of physical objects * Something that can be measured (or calculated from other quantities) Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.
A physical quantity described by both magnitude and direction is called what?
A physical quantity that is specified by both magnitude and direction is a vector by definition.
Do materials change whenn physical properties are measured?
Yes, materials do change when physical properties are measured.
What physical property can be observed but not measured?
Beauty cannot be measured.
Is Specific charge is scalar or vector?
specific charge is because a physical quantity can be complete only when by giving magnitude only. Here the physical quantity is complete by its magnitude.
How salinity temperature and density are measured by physical oceanographer?
they are measured with parometers
What physical quantity is measured in bars?
Air pressure is measured in bar.
What is 'physical benefits'?
Physical benefits are ones that can be measured physiologically
