Is there any physical quantity having no dimension but unit only?
Yes. Look at the Wikipedia aritcle on "dimensionless quantity". Here are two examples: 1. Angles, when measured in radians, can be considered the ratio of the arc of a circle to the radius. The result is a dimensionless number. 2. The coefficient of friction, which is the ratio between two forces. Dimensionless quantities often appear as a result of taking the ratio of two measurements.
Why does refractive index not have units?
Because it is the ratio of two speeds (which will have identical units), the units cancel.
What two quantities do you need to know in order to calulate density?
Mass and Volume
What is the quantity of two quantities in which the ratio of one quantitie to the other quantity is constant?
It is called direct variation.
Which two physical quantities must be measured in order to determine the density of a liquid?
Weight (mass) and volume.
What is a ratio that compares two quantities with two kinds of units?
A rate.
What is a ratio that compares two quantities that are measured in different units?
what is it
What is a ratio that compares two quantities with different kinds of units?
A rate.
What is a ratio comparing two quantities with different kinds of units?
A rate.
Ratio that compares two quantities measured in different units?
Its an inequality
A ratio comparing two quantities with different kinds of units?
Rate
Why specific gravity has no unit or dimensionless?
Because it's the ratio of two densities ... the density of the substance of interest to the density of water. In any ratio, the units of both quantities are the same, so the ratio winds up being a dimensionless number.
What is The ratio of two equal quantities each measured in different units?
Conversion factor.
What is a ratio that compares two quantities measured in different units?
it's a rate bro
What are some examples of physical quantities that do not have units?
This often happens if you take the ratio of two quantities. In that case, the units disappear. For example:* A coefficient of friction, defined as the ratio between two forces * The specific gravity, defined as a ratio between two densities
Ratio between two different quantities?
A ratio between two quantities, usually with differing units, is called the rate.When describing the units of a rate, "per" usually separates them.For instance: beats per minute, miles per hour, gallons per mile.
What does the golden ratio means?
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
