Atrough is filled with a liquid of density 815 kg/m3. the ends of the trough are equilateral triangles with sides 6 m long and vertex at the bottom. find the hydrostatic force on one end of the trough. (use 9.8 m/s2 for the acceleration due to gravity.)

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.

+10 that is always the common denominator
