It'll be useful to compare the size of an atom with something familiar; how about the thickness of a sheet of paper? The diameter of a hydrogen atom is about 1 Ă 10-10 m and the thickness of a piece of paper is about 0.05 mm. How many hydrogen atoms stacked up would it take to equal the thickness of the paper? Give your calculations and answer in the text box below; your answer should be a whole number.

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
