Final answer:

The Newton (N) and the Pascal (Pa) are two examples of derived units in the SI system; the Newton is a unit of force and the Pascal is a unit of pressure.

Step-by-step explanation:

The student asked for two examples of derived units in the SI system. Derived units are combinations of the seven base units that are part of the SI system. The base units include measures such as meters for length, kilograms for mass, and seconds for time.

Among the options presented (A) Newton (N), (B) Pascal (Pa), (C) Meter (m), and (D) Second (s), the derived units are:

  • Newton (N), which is a unit of force and can be expressed as kg·m/s² (kilogram meter per second squared).
  • Pascal (Pa), which is a unit of pressure and can be defined as a force of one Newton per square meter, or N/m².

The meter (m) and second (s) are both base units of the SI system, not derived ones.

Remembering that force is equal to mass multiplied by acceleration (F = ma) from Newton's Second Law can help identify that a Newton is a derived unit, as it involves kilograms (mass) and meters per second squared (acceleration). A Pascal is also derived, relating force in Newtons to an area measured in square meters.
