Shelli is a student describing the resonance of a metal beam. She demonstrates that the sound dims when the beam is vibrated at a certain frequency. What does she most likely say in response to the dimming sound?

“This is not the natural frequency of the beam.”
“This is the natural frequency of the beam.”
“The decibels are increasing.”
“The amplitude is not increasing.”

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
