A dentist's chair makes use of hydraulic system to move patients up and down. Together, the chair and a patient exert a downward force of 2,269 N. The chair is attached to a large piston with an area of 1,221 cm2. To move the chair, a
pump applies force to a small piston with an area of 88.12 cm? What force must be exerted on the small piston to lift
the chair?

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
