Input (English): In particle physics, this word names peaks in the cross section of a scattering experiment  corresponding to the indirect observation of short-lived particles. The "width" within which this effect  can take place is equal to the viscous coefficient over the mass, and as that gamma ratio decreases,  this effect becomes more pronounced. In LC circuits, this effect occurs alongside minimum impedance  at one over the square root of (*) inductance times capacitance. The Q-factor can be defined as the  ratio of this effect's associated frequency to the aforementioned width. Via a von Karman vortex street,  this effect destroyed the Tacoma Narrows bridge. For 10 points, name this increase in amplitude that  occurs when an oscillator is driven at its natural frequency.
Output (English): Science
