the surface of area of a small piston a is 0.01m^2, the surface area of the big piston A is 0.1m^2 and the effort is 150N, calculate the magnitude of the load F? (a)39N (b) 50N (c) 20N (d) 10N

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

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
