A pilot sets out to fly form B to A ,and wishes to set a course to offset a 32kph easterly wind The aur craft can fly at a speed 800kph in still air. A is 250km form B on a bearing of 30°.1.Illustrate the information above with a triangle of velocities 2.on what course must the aircraft be set 3.At what speed must the aircraft travel 4.How long will it take to travel to A to B.​ Maths:Vector Application

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
