Two long and straight conductors are parallel to the z-axis. conductor 1 carries a current i-10 a in the +z direction and is located at (-15.0 cm, 0). conductor 2 carries a current of 15 a in the -z direction and is located at (-15.0 cm, +20.0 cm). (a) what are the coordinates of the point where the net magnetic field due to the two conductors is zero? (b) if a third long and straight conductor, parallel to the z-axis and carrying a current is 20 a (same direction as ii) is placed at the origin, find the magnitude and direction of the magnetic force per unit length on this conductor due to the first two.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?
