The resistivity of a material is 2x10-3Ωm. What is the conductivity\n

The next element is345640

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.

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .

I'd go with c) winter because that such a small angle. i think summer is 70-90, and autumn/spring are like 40-70.
