A hydraulic lift is made by sealing an ideal fluid inside a container with an input piston of cross- sectional area 0.004 m2, and an output piston of cross-sectional area 2 m2. The pistons can slide up or down without friction while keeping the fluid sealed inside. What is the maximum weight that can be lifted when a force of 50 N is applied to the input piston?

25,000N of force will be ouputed

Explanation:

Detailed explanation and calculation is shown in the image below

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
