4/0 aluminum concentric neutral cable is to be used for a single-phase lateral. The neutral is #10 copper. The cable has a full neutral (see Appendix B). Determine the impedance of the cable and the resulting phase impedance matrix in Ω/mile assuming the cable is connected to phase b.

Determine the phase admittance matrix in μS/mile for the single-phase concentric neutral cable of Problem

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong
