Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
Can a quantity have units but still be dimension less give example?
No, "dimensionless" means, precisely, that there are no units.
Does a dimensionless quantity have a unit?
"Dimensionless" means it doesn't have a unit.
How to Find Volume when given mass and specific gravity?
Volume = mass / specific gravity. Units are cubic centimeters and grams or cubic meters and tonnes. s.g. has no units : it is a dimensionless quantity.
What are the dimensionless quantity?
A dimensionless quantity is one that has only a number, not a unit, and should therefore be the same in any system of units. This often happens when a quantity is the ratio of two measurements of the same kind. For example, the index of refraction can be considered the ratio of two speeds (the speed of light in a vacuum, and the speed of light in the corresponding substance); if both speeds are expressed in meters/second, when taking the ratio, the units disappear, and only a number without units - a "dimensionless" unit - remains. If you convert the speeds in this example to some other unit, for example kilometers per second, both speeds will be a thousand times less; but the ratio will still be the same.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
Which dimensionless quantity has unit?
If a quantity is "dimensionless", that means it has no units, and it's just a number.
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.
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 that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
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.
What is the rule of dimensionless quantity?
infinity
Can a quantity have constant value and be dimensionless?
Yes. Conversion factors will generally be dimensionless constants.
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.
How to Find Volume when given mass and specific gravity?
Volume = mass / specific gravity. Units are cubic centimeters and grams or cubic meters and tonnes. s.g. has no units : it is a dimensionless quantity.
