1. A dipole array consists of three, z-directed dipole elements placed along the y-axis at y=0, d and 2d. The 3 half-wave dipoles are uniformly excited. (a) Plot the radiation pattern in the xy-plane ($$|E_\theta|$$ vs. $$\phi$$) in polar form for d=$$\lambda/2$$ using the graphical method. (b) Repeat for d=$$3\lambda/4$$ and d=$$1\lambda$$. Describe what you observe as d is increased. Top View 1 2 3 $$\angle 0^\circ$$ $$\angle 0^\circ$$ $$\angle 0^\circ$$ y x $$\phi$$

Lions can run at speeds up to approximately 80.0 km/h. A hungry 109 kg lion running northward at top speed attacks and holds onto a 36.5 kg Thomson's gazelle running eastward at 79.0 km/h. Find the final speed $v_f$ of the lion-gazelle system just after the lion attacks. Find the angle $\theta$ between the final velocity of the lion-gazelle system and the East axis, with positive angles measured counterclockwise from the East axis. $v_f = \text{_____ m/s}$ $\theta = \text{_____}$
