Which of the following characterizes an alpha ray? Choose all that apply. is attracted to the positively charged plate in an electric field is electromagnetic radiation is composed of particles is less penetrating than a gamma ray carries a positive charge

Learned about life itself

B) as the temperature increases, the kinetic energy of the particles increases.|-/

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.
