Longitudinal Waves and Guitar Strings
According to the diagram this pressure wave consists of rarefactions and compressions. The compressions are regions of high pressure, whereas the air molecules are compressed within a small region of space. The rarefactions are regions of low pressure, while the air molecules are spread apart. This alternating pattern of compressions and rarefactions is called as a sound wave.
A step-up transformer has a primary coil having of 152 turns and a secondary coil with 3040 turns. The primary coil receives a peak voltage of 98 V. a. What is the effectiv
Two boxes are in contact on a flat table. A force of 75.8 N is applied horizontally to the first box, which in turn pushes horizontally against the second box. The mass of the firs

Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
Generate and plot a sampled sine wave with fs=8kHz, of 4 seconds duration, with frequency ?0 = ?/10 and amplitude A = 1.2. The waveform equation is x(n) = A sin n?
