Question 16 (5 points) A physics class has been split into four groups to complete the following activity: "create and act out a play that models the creation and propagation of sound waves in a gas (like air)." Below is what each group came up with: Group A: The students sit in a row, with the first person holding a ball labeled "energy." The student at the beginning stands up, then passes the ball to the student next to them before sitting back down. This continues for each student consecutively to the end of the row Group B: The students stood closely together in a line with their arms locked tight. Then the student at the beginning of the line passes the "energy" ball to the person next to them, keeping the locked arms, causing the ball to move quickly down the line Group C: The students stood spread out randomly along the classroom. One student began jogging with the "energy" ball till he hit another student, and then locked arms with them. The two students then continued running, and locking arms with other students. This continued until all the students were moving as one large group with the ball at the other end of the classroom Group D: The students stood spread out randomly along the classroom. The first person moves the "energy" ball across their body from left to right, and passes that ball to the closest person on their right. This process is repeated until the ball had been tossed to every person in the classroom at least once, from one end of the room to the other. Which group created and acted out a play that most accurately models the creation and propagation of sound waves in a gas (like air)?

Explanation / Answer

sound is a longitudinal wave and the propogation of energy in gas in the form of sound is such that the particles of the gas osscilate in the direction of propogation of energy such that energy is passed on from one point to the other.

henc eform the given four examples
Group D has the most close approximation of transfer of energy in gas, because when two people collide and transfger energy ball, the enrgy is transferred due to collision from one molecule of the gas to the another and this process continues till the energy has dissipated due to constant collisions of the gas molecules and dissipation of energy due to internal losses of the gas
