Three balls with masses of 1.0 kg, 1.0 kg, and 4.0 kg are located at coordinates (8.0m,6.0m), (7.5m,5.0m), and (2.5m,4.5m), respectively, and are connected by massless rods.1.what is the x-coordinate of the center of mass? 2.for the three balls above, what is the y-coordinate of the center of mass?

Ithink it is c ,i hope i you

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.

Dshould be the right answer i think

Bis the answerhope it !
