A bicycle tire of radius 0.40 m and mass 1.7kg is rotating at 62.9 rad/s. What torque is necessary to stop the tire in 2.2 s?
Answer in units of N · m.
This is now my third time asking this question for someone to answer, basically free points.

The duration of a photographic flash is related to an rc time constantly

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.

Ai think hope that
