1. The result is a frequency of vibration higher than the theoretical frequency. 2. The pitch of a note is determined by the frequency of vibrations . 3. In general, the higher the frequency of vibration , the higher the perceived pitch. 4. This adsorption occurs at the characteristic frequencies of vibration of the gas and dust. 5. Scanned synthesis involves a slow dynamic system whose frequencies of vibration are below about 15 Hz. 6. Taller buildings have their own frequencies of vibration . 7. Higher frequency of vibration improves component stratification along the screen and leads to better separation efficiency. 8. The frequency of vibration of the vocal folds is determined by their length, tension, and mass. 9. Singing requires a lot of fine motor control, using muscles to help change the frequency of vibration . 10. For high frequency of vibrations \ nu the kinetic energy can be large compared to the potential energy.
