A15 kg bucket of water is suspended by a very light rope wrapped around a solid uniform cylinder 0.300 m in diameter with mass 12.0 kg. the cylinder pivots on a frictionless axle through its center. the bucket is released from rest at the top of a well and falls 10.0 m to the water a. what is the tension in the rope while the bucket is falling? b. what is the acceleration of the bucket? c. with what speed does the bucket strike the water? d. what is the time of fall?

Then the answer would be d then

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.
