The gravitational effect of the moon on bodies of water on the earth create a simple harmonnic motion (SHM) which manifests itself as semi-diurnal tides: that is, two hight tides and two low tides in approximately one day. The interval between two high todes (or two low tides) is approx 12 hours and 25 minutes.
The tidal effect is very well modelled by SHM, for which the sine (or cosine) waves are solutions.
The gravitational effect of the sun and local geography also play a part in tides.
Electromagnet radiation must be converted to mechanical movement within the range of audio (20-20khz) to be heard.
Gamma waves have the shortest wavelength of any electromagnetic wave in the EM spectrum, the shortest wavelength means highest cyclic frequency, and highest intensity of any EM wave. (energy transferance by gamma waves is the strongest) *intensity is a measure of the height of the sine wave as opposed to to length, essentially more energy in a smaller crossectional area.
Yes, they can. Normal sound waves (the curvy kind) are called sinusoidal, because when graphed, they use equations with the trigonometry function sine. However, sound waves can also be triangular (pointed instead of normal curves), square (flattening at the top or bottom of the curve), or "sawblade" which is shaped like a saw blade. You can listen to examples of each of these on the wikipedia page for "non-sinusoidal sound waves" which I don't have the link for not but its pretty easy to find.
A simple wave function can be expressed as a trigonometric function of either sine or cosine. lamba = A sine(a+bt) or lamba = A cosine(a+bt) where lamba = the y value of the wave A= magnitude of the wave a= phase angle b= frequency. the derivative of sine is cosine and the derivative of cosine is -sine so the derivative of a sine wave function would be y'=Ab cosine(a+bt) """"""""""""""""""" cosine wave function would be y' =-Ab sine(a+bt)
Urban legends say that at 5 Hz, the "brown note", loud sound waves can make you lose control of your bowels. However, this is just a legend and has been proven false.
The obvious answer is the relationships between the sides and angles of triangles. Waves in the sea are an example of a sine wave. Tidal Experts and Meterologists alike use sine waves to help predict tides. Music will also emit waves that may often look like a sine wave and pure notes will look like sine or cosine waves. The speed of a swinging pendulum can be plotted as a sine wave as well as the sound of a tuning fork.

Waves are periodic function, as is the sine function.
a)set of sine waves b)set of sine waves with phase zero
See the link belowA sine wave is computed by a mathematical function. A pure sine wave in a physical sense would exactly match the calculated value in the function at every point in time.

Yes, because all sound waves can be modelled as sine (or cosine) waves, or combinations of sine waves.
None - except that we have a grasp of the mathematical properties of sine waves. Sine waves seldom occur in nature ... but they often come close enough to be approximated by a sine wave.
Do you mean "How do sine waves generate ?" Or perhaps you mean "How are sine waves generated?" Or something else, perhaps? No one can answer a question that is incomprehensible.
