A boy throws a ball of mass 0.24 kg straight upward with an initial speed of 24 m/s. When the ball returns to the boy, its speed is 15 m/s. How much work (in J) does air resistance do on the ball during its flight

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.

It maybe because uranus is made of gas but uranus has a solid core in the middle
