Asquare loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. the loop has total resistance of 0.8 ohms. it begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 t pointing out of the page. finally it leaves the field. 1. when totally in the field, what is the magnitude of the magnetic flux through the loop? 2. as the loop enters the field, what is the magnitude of the induced emf around the loop?

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
