To understand the nature of a sound wave, including its properties: frequency, wavelength, loudness, pitch, and timbre. sound is a phenomenon that we experience constantly in our everyday life. therefore, it is important to understand the physical nature of a sound wave and its properties to correct common misconceptions about sound propagation. most generally, a sound wave is a longitudinal wave that propagates in a medium (i. e., air). the particles in the medium oscillate back and forth along the direction of motion of the wave. this displacement of the particles generates a sequence of compressions and rarefactions of the medium. thus, a sound wave can also be described in terms of pressure variations that travel through the medium. the pressure fluctuates at the same frequency with which the particles' positions oscillate. when the human ear perceives sound, it recognizes a series of pressure fluctuations rather than displacements of individual air particles. based on the information presented in the introduction of this problem, what is a sound wave? a. propagation of sound particles that are different from the particles that comprise the mediumb. propagation of energy that does not require a mediumc. propagation of pressure fluctuations in a mediumd. propagation of energy that passes through empty spaces between the particles that comprise the medium

Based on the information presented in the introduction of this given problem, sound wave is a propagation of pressure fluctuations in a medium.

Option C

Explanation:

A sound wave, accordingly, comprises of substituting compressions and rarefactions, or areas of high and low pressure, moving at a specific speed. Put another way, it comprises of an occasional (that is, wavering or vibrating) variety of pressure happening around the balance pressure winning at a specific time and spot.

Balance pressure and the sinusoidal varieties brought about by the section of an unadulterated sound wave. Sound wave requires a medium in order to propagate while the light wave doesn't need the medium to propagate.

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).
