A solid sphere of radius 25 cm is positioned at the top of an incline that makes 26◦ angle with the horizontal. This initial position of the sphere is a vertical distance 1.9 m above its position when at the bottom of the incline. The sphere is released and moves down the incline. 25 cm M µ ℓ 26◦ 1.9 m Calculate the speed of the sphere when it reaches the bottom of the incline if it rolls without slipping. The acceleration of gravity is 9.8 m/s 2 . The moment of inertia of a spherewith respect to an axis through its center is 2 5 M R2 . Answer in units of m/s.

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.
