The chart below shows four identical wagans loaded with different amounts of bricks. Wagon w
Wagon X
Wagon Y
Wagon z
two pounds of bricks
three pounds of bricks
four pounds of bricks
five pounds of bricks
It the same amount of effort is applied to all four identical wagons, why would Wagon W move farthest?
A It has the least amount of mass, affecting its motion.
B It has the least amount of speed, affecting its motion.
CIt has the greatest amount of gravity, affecting its motion.
D. It has the greatest amount of friction, affecting its motion

Divide 108.2 x 10^6 into 1.5 x 10 and the result will be in au (astronomical units)

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.
