Astar of mass 3 × 1030 kg is located at < 6 × 1012, 2 × 1012, 0> m. a planet of mass 6 × 1024 kg is located at < 4 × 1012, 4 × 1012, 0> m and is moving with a velocity of < 0.6 × 104, 1.1 × 104, 0> m/s. (a) during a time interval of 1 × 106 seconds, what is the change in the planet's velocity?

The rearrangement of particles in a physical change. hope 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.
