Determine the magnitude of the transfer function M=\frac{\sqrt{\left(c^{2} \omega^{2}\right)}}{\sqrt{\left(-m \omega^{2}+k\right)^{2}+c^{2} \omega^{2}}} M=\frac{\sqrt{\left(c^{2} \omega^{2}\right)+k^{2}}}{\sqrt{\left(-m \omega^{2}+k\right)^{2}+c^{2} \omega^{2}}} M=\frac{-c^{2} \omega^{2}}{\sqrt{\left(-m \omega^{2}+k\right)^{2}+c^{2} \omega^{2}}}
