#### Represent each of the following combinations of units in the correct SI form using an appropriate prefix: (a) kN/μs, (b) Mg/mN, and (c) MN/(kg•ms).

Solution:

a) $kN/\mu s=\frac{\left(10^3\right)N}{\left(10^{-6}\right)s}=10^9\:N/s=GN/s$

b) $Mg/mN=\frac{\left(10^6\right)g}{\left(10^{-3}\right)N}=10^9\:g/N=Gg/N$

c) $MN/\left(kg\cdot ms\right)=\frac{10^6\:N}{kg\cdot \left(10^{-3}\right)s}=10^9\:\frac{N}{kg\cdot s}=GN/\left(kg\cdot s\right)$
