A city in the Pacific Northwest has hundreds of sensors along a natural fault line. These sensors are part of an early detection and warning system, and they are constantly recording and storing seismic data for analysis. The sensor data are then used to predict the likelihood of an earthquake occurring at any given moment, how powerful the earthquake(s) will be, and the epicenter within a 15-mile radius. What kind of Big Data usage is this an example of?

It is d, all the other ones say incorrect answer .

Aliquid is an answer i 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.
