If i am throwing away trash out of a five story building and i throw out a pair of socks into a dumpster below, which will fall faster the socks that a folded together in a ball or the ones that are just flying loose and completely unfolded? why?

I'll do it rn and then answer

Velocity is the speed of an object in a certain direction so you'd need to know speed and direction

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.

Lexy is correct because angle r is between the incident wave,  n  = 0, and a diffracted wave.
