Therefore, the amplitude of the pendulum’s oscillation is A =0.140 m = 14.0 cm. Example 2 Assume that the head of a jack-in-the-box toy is bouncing upward and downward on a spring. Furthermore, the angular frequency of the oscillation isω=π/6radians/s, and the phase shift isϕ...
Green frogs increase the peak frequency of their calls when suddenly exposed to loud anthropogenic noise34. Playback treatments caused spring peepers Pseudacris crucifer to produce shorter calls, the high-frequency noise treatment caused them to lower the frequency of their calls immediately after the ...
