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 is a ratio that compares two quantities that are measured in different units?
what is it
What are those derived quantities in units?
Derived quantities are physical quantities that are derived from base quantities through mathematical operations like addition, subtraction, multiplication, or division. These derived quantities are also represented in units based on the units of the base quantities used in their calculation. Examples of derived quantities include velocity, acceleration, and density.

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.
What is a derived unit?
A derived unit is a unit of measurement that is created by combining base units through multiplication or division. It is used to express physical quantities that are derived from fundamental physical quantities. Examples of derived units include the newton (N) for force and the joule (J) for energy.
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 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
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
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.
