What quantity and unit does the abbreviation K represent?
Quantity K is metric for 1000. For units, it can also refer to Kelvin temperature. It can also refer to Kinetic energy.
A fraction whose numerator and denominator represent the same quantity but use different units?
A unit conversion ratio
Why is the fundamental value of a quantity not changed when the quantity is multiplied by a conversion factor?
the conversion factor merely changes the number in such a way that it fits the new units the physical quantity is not changed
What are the two parts of measurements?
The quantity (magnitude, numrical value) and the units (eg inch, metre, light year)
What is done to a variable to represent a unknown quality?
Nothing specifically is "done" to the variable; variables are generally used to represent either:* A quantity that is initially unknown (and should be solved for), or * A quantity that can be anything - to analyze what happens no matter what a certain value is.
What quantity do units represent in a value?
they show the magnitude
Is a value a number that represents a quantity or an amount?
Yes, a value can represent a quantity or amount.
what quantity has no units?
Pure numbers, such as counting numbers or mathematical constants, typically have no units attached to them. These quantities are dimensionless and represent a specific value without a particular physical unit of measurement.
Numbers?
A number is an arithmetic value used to represent quantity.
Does magnitude of the quantity change with change in the system of units?
No, the magnitude of a quantity does not change with a change in the system of units. The numerical value representing the quantity may change based on the system of units used, but the magnitude itself remains constant.
What is quantity 50k?
Quantity 50k typically refers to 50,000 units or pieces of a specific item. It is a common abbreviation in the business world to represent a large quantity in a simplified format.
What quantity and unit does the abbreviation K represent?
Quantity K is metric for 1000. For units, it can also refer to Kelvin temperature. It can also refer to Kinetic energy.
Are dimensionless quantity always unitless?
Yes, dimensionless quantities are always unitless. This means they do not have any physical units associated with them, and they represent a pure numerical value that is independent of any specific unit of measurement.
A fraction whose numerator and denominator represent the same quantity but use different units?
A unit conversion ratio
In a conversion factor what is special about the fraction used?
In a conversion factor, the numerator and denominator of the fraction represent the same quantity but are expressed in different units. This allows you to convert from one unit to another.
What is meant by unit of a physical quantity in physics?
The unit of a physical quantity in physics is a standardized way to express and measure that quantity. Units give the quantity a numerical value and specify the scale at which it is being measured. Units are essential for consistency and clarity when communicating about physical quantities.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
