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
Does a dimensionless quantity have a unit?
"Dimensionless" means it doesn't have a unit.
What are dimensionless numbers?
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
Can a quantity have constant value and be dimensionless?
Yes. Conversion factors will generally be dimensionless constants.
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.
Is the magnitude of a vector quantity a dimensionless number?
Yes, the magnitude of a vector is a scalar.
Can a quantity have units but still be dimension less give example?
No, "dimensionless" means, precisely, that there are no units.
What are the units of the coefficient of friction?
The coefficient of friction is a scalar quantity which has no direction which does not have an angle.
What are the units that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
What is the unit for energy efficiency?
Efficiency is a dimensionless quantity, i.e. it's just a number, without any unit.
