10. Which of the open-loop functions has the following Bode plots: Magnitude (8) Phase (de) 0 -50 -100 -90 -135 -180 -270 (a) G(s) = 10 24 s(s+2)(s+6) (c) G(s) = 24 s² (s+6) 10⁰ G(s) = Bode Diagram Frequency (radise) 10 24 s² (s+2)(s+6) (b) G(s)=- 10² (d) G(s) = 10 s² +0.5s +10 11. Determine the number of unstable open-loop poles for the following system, s-3 s(s+6)(s-10)(s-12) (a) P=3 (b) P=2 (c) P = 4 (d) P = 5 12. For the system in Problem 11, the closed-loop system is stable if and only if (a) the Nyquist diagram encircles the (-1, 0) point twice clockwise (b) the Nyquist diagram does not encircle the (-1,0) point (c) the Nyquist diagram encircles the (-1, 0) point twice counterclockwise (d) the Nyquist diagram encircles the (-1, 0) point three times counterclockwise 13. Consider the following Nyquist Diagram,
