Question

take g = 9.8 m/s²

1. the si unit for density is

(a) kg/m²
(b) newton (n)
(c) pascal
(d) watts
(e) none of the above

Explanation:

Density is defined as mass per unit volume. The SI - unit of mass is kilogram (kg) and the SI - unit of volume is cubic - meter ($m^{3}$). So, the SI - unit of density is $kg/m^{3}$. Given options (a) $kg/m^{2}$ is not the unit of density, (b) Newton (N) is the unit of force, (c) Pascal is the unit of pressure, (d) Watts is the unit of power.

Answer:

E. none of the above
