Please Give all places after decimal A metal wire of mass 57 kg slides without friction on two horizontal rails spaced a distance of 16 m apart. The track lies in a vertical uniform magnetic field of 13 T. A constant current 45 A from a generator flows down one rail, across the wire, down the other rail back to the generator. Find the velocity of the wire at t = 29 s, assuming it to be at rest at t = 0. Answer in units of m/s 016 10.0 points At what distance from a long, straight wire carrying a current of 8 A is the magnetic field due to the wire equal to the strength of the Earth's field, approximately 2 × 10-5 T?
