Makai Estioko May Chang English 101 30 November 2015 Paddle surfing big waves Surfing is the art of riding breakings waves using any number and styles of boards, watercraft, or one’s own body. Surfing has been a part of the Polynesians cultures for thousands of years. Europeans were first introduced to surfing by Lieutenant James King of Captain James Cook’s crew in 1769. Cook wrote about surfing he witnessed while exploring the Hawaiian Islands. Three Hawaiian princes attended St. Matthew’s Hall

somehow encoded as a wave. Everything travels as a wave. Figure 6 represents a basic sine wave. The vertical axis is the volume, or air pressure, or strength, or energy, or amplitude etc. For example this is an ocean wave, and then the vertical axis may be the wave height. If this is a sound wave in the air, then it is the air pressure. If it is a sound wave in a wire, then it is the voltage. The horizontal axis often represents the time or distance that the wave traverses in. waves generally have a

When the transverse waves occur they mostly occur on solid and liquid state. The particles of the transverse waves moves perpendicular where the direction of the wave move. The longitudinal wave is a wave that particles move parallel to the direction where the wave moves. It mostly occur on the air, such as the sound. The difference between the transverse wave and the longitudinal is that transverse travels on a perpendicular way and the longitudinal travels on parallel, they both may transport energy

AC signals. The three types of circuit include the integrator, the AC inverting amplifier and the AC non-inverting amplifier circuit. The integrator circuit was tested with a square-wave and a sinusoidal wave input signal at 1kHz frequency. The results showed that the square-wave input signal produced a triangular wave output whereas the sinusoidal input produced a sinusoidal output signal with a positive 90 degree phase shift. Both output signals were showed to be the integral of their relative input

Earthquakes If one could have stood out in space for a fantastically long time and looked back at the Earth, one would have seen the continents themselves in motion, drifting apart on their crustal plates, held afloat by the fire beneath. That is a poetically turned phrase from Lewis Thomas, which beautifully sums up the mechanics behind plate tectonics, and ultimately behind earthquakes. The following is a brief sketch on earthquakes, their cause and effect, how they are measured, and an area where

Gravitational waves: Understanding and Detection Final draft Physics 222 November 11, 1999 Aaron Astle Dan Hale Dale Kitchen Wesley Krueger Abstract Gravitational waves carry information about catastrophic events in the universe. We give a brief description of gravitational waves with an overview of the current projects underway to detect them. We begin by discussing the theoretical prediction of gravitational waves from Einstein's General Theory of Relativity. We list several possible

Abstract: The purpose of this experiment was to verify the relationship between frequencies, wave length and wave velocity of a transverse wave on a string, as well as the relationship between the spring tension and the number of standing waves formed. Two different strings used in this experiment are white and black in colour; the µ1 value calculated for the white string is 2.73 x 10-3 ±0.00055kg/m with an uncertainty of ±8.2932 x 10-5 kg/m while the µ2 value calculated for the black
