Final answer:
The m · kg/s unit is classified as a derived unit made from the combination of three SI base units: meter, kilogram, and second. Option C is correct .
Step-by-step explanation:
The unit m · kg/s is a unit of measurement for momentum or mass flow rate and can be understood in the context of physics, particularly when discussing motion and the properties of fluids. This unit is a derived unit, made from a combination of three base units within the SI (International System of Units).
The SI base units are the meter (m) for length, the kilogram (kg) for mass, and the second (s) for time. When these base units are combined through mathematical operations such as multiplication or division, we get what are known as derived units. Therefore, the unit m · kg/s is composed of the base units meter (m), kilogram (kg), and second (s). Hence, the correct answer to the question is: C. derived unit; base units
