2. A wave on the ocean has a frequency of 2 hertz and a wavelength of 0.25 meters. How long will it take the wave to travel 1 kilometer?
(Please show work)

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.

Carbon dioxide because it consists of one type of molecule.

Answerok the answer is (all)
