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 harmonic mean is a better average when the numbers are defined in relation to some unit. The common example is averaging speed. For example, suppose that you have four 10 km segments to your automobile trip. You drive your car: 1  100 km/hr for the first 10 km. 2  110 km/hr for the second 10 km.
