Sound waves are introduced to a medium by a vibration. For example, a vibrating guitar string forces surrounding air molecules to be compressed and expanded. This creates a pressure disturbance consisting of an alternating bands of compressions and rarefactions. The vibration travels from particle to particle through the medium, transporting energy as it moves. The amount of energy which is transported past a given area of the medium per unit of time is known as the intensity of the sound wave and is reported as power area . All BUT one of these factors influence the intensity of a sound wave. That is A) the density of the medium. B) the amplitude of the wave. C) the source of the sound wave. D) your distance from the sound source.

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
