Aperson cannot see clearly objects closer than 2.00 m from her/him. what is the refractive power (in diopters) of the correction lenses that will allow her/him to clearly see objects located 30.0 cm, but not closer, from her eyes? ignore the distance between her/his eyes and the lenses.

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
