The coordinate plane below shows the path of a bicyclist. Each square represents 10 meters. B(0,3)

C (2,3)

A(0.0)

F(4,0)

D(2,-1)

E (4, -1)

A)what is the displacement of the cyclist? B)what is the distance traveled by the cyclist? C) if the whole trip takes 30 seconds , what is the average speed of the cyclist? D) if the whole trip takes 39 seconds, what is the average velocity of the cyclist E) between points A and B the cyclist increases his speed form 2 m/s to 5 m/s in a time of 2 seconds .what is magnitude of his acceleration?

Is it b the answer and yes

It indicates no change in temperature and the process of matter changing its state

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.
