Awire carries a steady current of 2.20 a. a straight section of the wire is 0.750 m long and lies along the y axis within a uniform magnetic field, = 2.00 t. if the current is in the positive y direction, what is the magnetic force on the section of wire?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
