(a) Draw a vector diagram to scale as much as possible) (b) Calculate the displacement each person/object moves.
1. A bird flying south at 25-km/hour encountered a crosswind giving it a resultant vector of 28-km/hour SE. What is the magnitude and direction of the crosswind?

What is the things about?

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.
