Is this true that conversion factor is a ratio of equivalent values used to express the same units in different quantities?
No. The same quantities in different units.
What does units agree mean?
In mathematics, two quantities are said to be in units agreement if they have the same units of measure. For example, if two quantities are both measured in meters, then they are in units agreement. If one quantity is measured in meters and the other is measured in centimeters, then they are not in units agreement.
Must quantities have different units before they can be added or subtracted?
no
What is a ratio that compares two quantities that are measured in different units?
what is it
Two quantities that have the same units have the same dimensionality?
True-
What is the following units that can only describe scalar quantities?
seconds grams
Which of the following are units that can only describe scalar quantities?
the units of mass gm and kg in CGS and SI system ,units of distance-m and km are some units which describe scalar quantity.
Ratio that compares 2 quantities measured in different units?
ratio that compares 2 quantities measured in diiferent units
What are subsidiary quantities and units in SI?
Subsidiary quantities and units are bigger or smaller than main units of measurement. For example, centimeters and kilometers are both based on meters.
Is this true that conversion factor is a ratio of equivalent values used to express the same units in different quantities?
No. The same quantities in different units.
5 What is absolute Units?
a unit defined in terms of units of fundamental quantities
What are the units of vector and scalar quantities?
The units will vary, depending on what you want to measure.
Which physical quantities does not have units?
specific gravity
What are derived quantities what are the fundamental quantities?
Fundamental quantities are quantities that can be measured such as mass, length and temperature. Derived quantities are quantities that has to be calculated such as pressure, volume and work done.AnswerThe SI does not define 'fundamental quantity', instead it uses the term 'Base Unit'. All other units are 'Derived Units', so-called because they are each derived from combinations of Base Units.
What are the importance of using standard units in measurements?
# Units allows use to compare quatities that are not in the same space, place or time # units also indicates the physics quantities measured or been measure as each quantities has particlar units
