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

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
