Atissue sample from a mammalian heart was measured for its resistivity. held at room temperature, its resistivity is around 1.40 m. calculate the resistance of a tissue sample with 1.00 mm in length and diameter of 2.00 mm. calculate the new resistivity and resistance of the sample when a solution with caand my is introduced and decreases the original resistivity by 32.0%. calculate the old and new conductivities of the sample. which is a better conductor?

Arise 8 run 1 this means go 8 up and 1 across, which is steepest

The answer would be a) -80of

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.
