What is a ratio of two quantities that have different units?
It is a rate. For instance, if the quantities are 10 km and 2 hours, then the ratio (10 km)/(2 hours) = 10/2 km/hour = 5 km/h, which is a rate of speed.
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.
Why can quantities with different units never be added or subtracted bwhy can quantities with different units never be added or subtracted but can be multiplied or diviut can be multiplied or divided?
Only like terms can be added or subtracted. 10m and 1s cannot be added; but divided, 10 m/s becomes a velocity.
What are the three physical quantities with units?
The three fundamental physical quantities with units are mass, length, and time. Mass is measured in kilograms (kg), length in meters (m), and time in seconds (s). These quantities form the basis for various derived units and are essential in various scientific calculations and measurements.

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 are derived quantities that are defined in terms of the base quantities in the International System of Units (SI), such as area and volume. Units for these quantities are formed by multiplying or dividing the base units according to their definitions. For example, the unit of speed, meter per second (m/s), is a derived unit formed from the base units of length (meter) and time (second) in SI.
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 is a derived unit?
derived units come from basic units such as length, time, electrical current.AnswerIn SI, Derived Units are any units that are not Base Units. There are seven Base Units, from which all Derived Units are formed. For example, a coulomb (derived unit) is equal to an ampere second (both Base Units).
Which physical quantities does not have units?
specific gravity
What are the units of vector and scalar quantities?
Vector quantities have both magnitude and direction, so they are expressed in units such as meters per second (velocity) or newtons (force). Scalar quantities only have magnitude and are represented by units such as meters (distance) or kilograms (mass).
5 What is absolute Units?
a unit defined in terms of units of fundamental quantities
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
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.
What are those derived quantities in units?
Derived quantities are physical quantities that are calculated from two or more base quantities. They are expressed as a combination of base units using mathematical operations such as multiplication, division, and exponentiation. Examples of derived quantities include velocity (derived from distance and time) and density (derived from mass and volume). These derived quantities play a crucial role in physics and other sciences for describing and understanding complex relationships between different physical quantities.
