In the figure, a radar station detects an airplane approaching directly from the east. at first observation, the airplane is at distance d1 = 320 m from the station and at angle θ1 = 31° above the horizon. the airplane is tracked through an angular change δθ = 124° in the vertical east–west plane; its distance is then d2 = 800 m. find the (a) magnitude and (b) direction of the airplane's displacement during this period. give the direction as an angle relative to due west, with a positive angle being above the horizon and a negative angle being below the horizon.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
