What are the three fundamental dimensions used in Physics?
Length, mass, and time are the three fundamental dimensions on which the measurement of all physical quantities is dependent.
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
What are three physical quantities with units?
Length. Meter Mass. Kilogram Time. Second
Which physical quantities does not have units?
specific gravity
Which physical quantities does not have any units?
specific gravity
Give at least 10 physical quantities and their units?
Write about 10 instruments which are used to measure different physical quantities i.e. - mass, volume, time and temperature
Why do you need to measure physical quantities and express them using the appropriate units?
to know what is the measure
What are the physical quantities and units included in determining speed?
-- The physical quantities involved in speed are distance and time. -- Some popular units of distance include the mile, foot, kilometer, smoot, and parsec. -- Some popular units of time include the second, month, week, fortnight, and year.
Which of these physical quantities does not have any units specific gravity resistance distance inertia?
what is the smallest prime number
What are the quantities in the metric system?
The units are: -- Kilogram -- Meter -- Second. All of the other units in the metric system are fractions, multiples, or combinations of these three.
Types of physical quantities?
Physical Quantities are of TWO types: 1) Fundamental Quantities. 2) Derived Quantities.
Why is it important to have clearly defined quantities and units in measurement?
Because.... There are two types of physical quantities. Fundamental and derived. Fundamental units cannot be derived from any of the two types of units while derived units can be derived from these two types of units. It's important to be clearly defined as there are so many indices of the base number. And no one can derive the units if they aren't properly defined
What are the fundamental quantities?
The fundamental units are those of the SI system - The unit of Temperature, Kelvin; of Time, the second; of Mass, Kilogram; of brightness, the Candela; of physical quantity, the Mole; and of electrical current, the Ampere. With these units, all fundamental quantities may be described.Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
Ratio that compares 2 quantities measured in different units?
ratio that compares 2 quantities measured in diiferent units
