A dumbbell-shaped object is composed by two equal masses, mm , connected by a rod of negligible mass and length rr . If I1I1 is the moment of inertia of this object with respect to an axis passing through the center of the rod and perpendicular to it and I2I2 is the moment of inertia with respect to an axis passing through one of the masses, it follows that

A) acceleration. this seems to be the one that makes sense.

Iknow the first part it is the average star i am not 100% sure

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 fusion
