One piston in a hydraulic lift has an area that is twice the area of the other.When the pressure at the smaller piston is increased by$\Delta$p the pressure at the larger piston:
A)increases by 2$\Delta$p
B)increases by $\Delta$p/2
C)increases by $\Delta$p
D)increases by 4$\Delta$p
E)does not change

According to Pascal's principle, a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container. Therefore, if the pressure at the smaller piston is increased, the pressure at the larger piston increases by the same amount, regardless of the difference in area.
