2075Which are resistive loads & which one are inductive loads : Refrigerator, Split air conditioner, ceiling fans, well pump, fluoresecent bulbs, T.V, CRT Monitors, Adsl Routers, C.P.U, Printers, Deep Freezers, Speakers, DVD Players, Microwave oven etc. ? Output Power for these Appliances Would be same like this : P = V * A * P.F Or would be changed ? thanks

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
