A300-mile long, 230 kv loop connects a number of substations. the fault level at the point of supply for the loop is 5000 mva. the loop impedance is 0.5 ohm/mile. the test substation is located 50 miles away of point of supply. plot sag voltage on such bus vs. distance to fault for faults occurring on the 250 mile branch (use 50 mile intervals).

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
