Can a quantity have constant value and be dimensionless?

Yes. Conversion factors will generally be dimensionless constants.

Is the magnitude of a vector quantity a dimensionless number?

Yes, the magnitude of a vector is a scalar.

Is relative dielectric constant dimensionless?

Correct: it is a dimensionless number.

Is calcium's relative value per ounce pound or ton?

Relative value is a dimensionless quantity, and so it shouldn't matter what units you want to use, as long as you are consistent.

How do you prove dimensionless groups?

A dimensionless number has no units. The units of all variables that compose the dimensionless number (product or ratio) must cancel each other.

Which dimensionless quantity has unit?

If a quantity is "dimensionless", that means it has no units, and it's just a number.

Is specific weight is a dimensionless quantity?

energy/mass example: calories/gram

Can a quantity have units but still be dimensionless?

No. "Dimensionless" means there are NO units involved.

What are dimensionless numbers?

the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.

Does a dimensionless quantity have a unit?

No, a dimensionless quantity does not have a unit because it represents a pure number without any physical dimension. Examples of dimensionless quantities include ratios, proportions, and mathematical constants.

Can a quantity have constant value and be dimensionless?

Yes. Conversion factors will generally be dimensionless constants.

Can a quantity be dimensionless and have no units?

Yes, a dimensionless quantity is a quantity that does not have any physical dimensions or units. It is a pure number or ratio that represents a comparison between two quantities. Examples of dimensionless quantities include angles, ratios, and pure numbers like pi.

Can a quantity have unit and still be diamensionless?

No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.

Is the magnitude of a vector quantity a dimensionless number?

Yes, the magnitude of a vector is a scalar.

Which of the following is dimensionless quantity a. stress b. strain c. momentum d. force?

Strain is dimensionless quantity because strain is the ratio of the same quantities like change in length/original length,,change in volume/original volume. e.g tensile strain=(change in length)/(original length)=m/m (S.I unit) so its a dimensionless quantity.

Can a quantity have units but still be dimension less give example?

Yes, a quantity can have units but still be dimensionless if the units cancel out when they are raised to the power of 0. For example, specific volume (volume per mass) has units of m^3/kg, but when you divide volume by mass, the units cancel out and it becomes dimensionless.

What are the units that friction is measured in?

The coefficient of friction is dimensionless; it has no units.
