The cable from drum a turns the double wheel b, which rolls on its hubs without slipping. determine the angular velocity ω and angular acceleration α of drum c for the instant when the angular velocity and angular acceleration of a are 3.9 rad/s and 2.8 rad/s2 respectively, both in the counterclockwise direction. the angular velocity and acceleration of c are positive if counterclockwise, negative if clockwise.

Less force and energy was applied

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.
