Calculate the torque produced by a motor that has 500 windings across a 30cm diameter rotating core. The core is 0.6 M long inside a 50 tesla magnetic field. The resistance of the wire is 30 ohms when 12 volts are applied.

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
