Question

1. which best describes the term derived unit in si? a specific combination of base units with its own name a prefix multiplier for a base unit a conversion factor between base units one of the metric base units that is the foundation of si

Explanation:

Derived units in SI are formed by combining base units. For example, the unit of force, the newton ($N$), is a combination of base units ($kg\cdot m/s^{2}$) and has its own name. A prefix multiplier (like kilo - for $10^{3}$) just scales a base unit. A conversion factor is used to change from one unit system to another (e.g., from inches to meters). The metric base units (like meter for length, kilogram for mass) are the fundamental units, not derived units.

Answer:

a specific combination of base units with its own name
