At a picnic, there is a contest in which hoses are used to shoot water at a beach ball from three directions. as a result, three forces act on the ball, 1, 2, and 3 (see drawing). the magnitudes of 1 and 2 are f1 = 40.0 newtons and f2 = 80.0 newtons. using a scale drawing and the graphical technique determine the following such that the resultant force acting on the ball is zero.

This did i unseated, sorry

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.
