A dentist's chair with a person in it weighs 1950 N. The output plunger of a hydraulic system starts to lift the chair when the dental assistant's foot exerts a force of 44 N on the input piston. Neglecting any difference in the heights of the piston and the plunger, what is the ratio of the area of the plunger to the area of the piston? Aplunger Apiston
