Answer:
Proof in explanation.
Explanation:
a.
Pa is the unit of pressure and pressure is given as:
[tex]Pressure = \frac{Force}{Area}[/tex]
The units are:
[tex]Pa = \frac{N}{m^2}[/tex]
N is itself a derived unit. Hence, it is proven that Pa is a derived unit.
b.
Pa is the unit of work and work is given as:
W = (Force)(Displacement)
The units are:
J = (N)(m)
N is itself a derived unit. Hence, it is proven that J is a derived unit.
