5. a cyclist is traveling along a level, straight road at 10 m/s in the positive direction with a x; = v. in
magnitude of the velocity for the cyclist is tracked using the following motion graph.
velocity-time graph
velocity (m/s)
0 1 2 3 4 5
time (s)
according to the information and graph shown above, what is the magnitude of the acceleration for the first
two seconds?
a. 2 m/s2 ~
c. 12 m/s2
b. 24 m/s2
d. 1 m/s2

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.
