Athree-phase overhead line 200km long has resistance = 0.16ω/km and conductor diameter of 2cm with spacing 4m, 5m and 6m transposed. find: (a) the abcd constants, (b) the vs, is, pfs, i when the line is delivering full load of 50mw at 132kv and 0.8 lagging pf,(c) efficiency of transmission, and (d) the receiving-end voltage regulation.

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?
