W : Build on studentsâ knowledge of literary elements by explaining how to draw conclusions, including determining the theme, based on information in folklore. H : Engage students by using the story Goldilocks and the Three Bears to model how to draw conclusions based on text.
For a signal whose fundamental frequency is f, the second harmonic has a frequency 2 f, the third harmonic has a frequency of 3 f, and so on. Let w represent the wavelength of the signal or wave in a specified medium. The second harmonic has a wavelength of w /2, the third harmonic has a wavelength of w /3, and so on.
The second (symbol: s) (abbreviated s or sec) is the base unit of time in the International System of Units / SystÃ¨me International d'UnitÃ©s (SI). It is qualitatively defined as the second division of the hour by sixty, the first division by sixty being the minute.
