Asingle-phase overhead transmission line consists of two solid aluminum conductors having a radius of 3 cm with a spacing 3.5 m between centers. (a) determine the total line inductance in mh/m. (b) given the operating frequency to be 60 hz, find the total inductive reactance of the line in v/km and in v/mi. (c) if the spacing is doubled to 7 m, how does the reactance change? 4.14 (a) in practice, one deals

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
