Question

state two difference between base si unit and derived si units

Answer 1

Base SI unit is the unit that used for simple quantity like time=second and length= meter. They only have one unit.Derived unit is more complex because you multiply or divide at least two base SI, making it have more than 1 unit. The example could be velocity which was time/length = m/s The base units in the SI are meter, kilogram, second, kelvin (degree of temperature), ampere (electric current), mole (quantity of substance) and candela (luminosity).Everything else in the SI can be derived from those base units. If it’s not a base unit, it’s a derived unit.
