An object, initially at rest, is subject to an acceleration of 34 m/s2. how long will it take for that object to travel 3400 m?

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire
