Plz help What is the range of a projectile launched at an angle 25º with an intial velocity of 27 m/s and
traveled in the air for 2.5 s?

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .

Ithink it is letter b, i may be wrong but i think that is the answer

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.
