Help me answer these 10 questions on resonance in Physics

HWIO: Resonance 1. A standing wave i3rcl harmonic) in an open-closed pipe has a frequency of f3: 226 Hz. The speed of sound is 340 m/s. What is the wavelength of this standing wave? meters. What is the length of the pipe? meters (v = A" fn and A": 4L) 2. The 4'\" harmonic of a standing wave on a string with tied ends is 444Hz. What is the fundamental frequency f1: ? 3. The resonant frequency of a circuit is 655 Hz, and the bandwidth is 200 Hz. The upper and lower cutoff frequencies are and 4. A resonant curve has a peak at 800Hz and a bandwidth of 275Hz. What is the 0. factor of this curve? 5. If a resonant cavity amplifies signals of frequencies in the range of 300-450 Hz, then it acts as a filter. 6. If a resonant cavity amplies all signals above 300 Hz, then it is a filter. if 7-10 TRUE OR FALSE 7. If you vibrate an object, it will have sustained oscillations only at its NATURAL frequency. 8. At resonance, amplitude of oscillation and energy are maximized. 9. Most resonant systems in nature are broadly tuned. 10. In a resonance curve, the lower cutoff frequency of a resonant curve is 5dB below max intensity
