Abox at rest on a ramp is in equilibrium, as shown. what is the force of static friction acting on the box? round your answer to the nearest whole number.

How have the competing explanations' experiments on atoms affected the development of the atomic model?

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

Most short-period comets do not have randomly oriented orbits because
