Ahardworking ant must supply 0.00805 n to pull a small piece of fruit at constant velocity over a distance of 9.80 cm up a small hill to the entrance of the colony. if the coefficient of kinetic friction between the piece of fruit and the 15.8â° sloped hill is 0.400, calculate the work done by the ant by pulling the piece of fruit up the hill.

In physics, the definition of work is simply the product of force exerted and the displacement. Therefore in this case, work done by the ant is:

Work = 0.00805 N * 9.80 cm * (1 m / 100 cm)

Work = 7.889 x 10^-4 J

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.
