Three sleds of masses mı, m2, and m3 are on a smooth surface (ice) inclined at an angle relative to the horizontal and
connected by ropes as shown in (Figure 1). Imagine that you
exert force of a known magnitude T on the rope attached to the
first sled.
determine the magnitude of the tension in the rope that connects sled one (mass M1) and sled two (mass M2). determine the magnitude of the tension in the rope that connects sled 2 (mass m2) and sled 3 (mass m3)

Kiloleter, mega leterhope this !

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.
