The trough springs a leak when the water level is 1.2 meters and the rate at which the water level is rising drops to 1/6 meters per second. Find the rate at which water is leaking out of the tank when the water level is 1.2 meters

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.

Ithink the answer is d

Idk idk idk idk idk idk idk idk idk ikd idkk
