HELP URGENT A bacterium has a length of 5.5 10–6 m but seen through a powerful microscope appears to be 1.2 10–3 m. What is the magnification of the microscope?

B) raising the temperature and reducing the volume of the gas.|-/ 

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.
