several lemons are placed on a spring scale at a grocery store. If the the lemons have a combined mass of 1.01kg, what is the spring force in the spring while the objects are being weighed?

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

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
