Whiz idea did Issac Newton’s experiments with light support
Light is produced by the interaction of magnetic and electric fields
Light is a wave because it has properties that are similar to radio waves
Light is made of particles because it travels only in a straight path
Light is a wave because it bends around barriers

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
