The amount of pressure exerted by a solid is based on
the mass of the object.
the mass of the object and the area of the bottom surface.
the density of the object and the frictional coefficient of the surface it's
contacting.
the mass of the object and the density of the material it's contacting.

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects

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
