Context: In a New York City residence, Pierre Delacroix (Damon Wayans) rises to begin his daily routine. Brushing his teeth, he gives us by voice over a definition of satire. He tells us that with the rise of the Internet, video and interactive games, his field as a television writer has seen a drop in popularity. Meanwhile, in a dilapidated building, squatter Womack (Tommy Davidson) wakes up his friend Manray (Savion Glover) for a day of work. This consists of travelling to the CNS (Continental Network System) building where Delacroix works, and Manray tap dancing to entertain the workers. They then collect money from the workers. The men see Delacroix walk by, and ask him for monetary help in the form of work of some kind.Delacroix walks into a staff meeting late and is immediately castigated by his boss, Thomas Dunwitty (Michael Rapaport). Dunwitty informs the staff that CNS has poor ratings. He says he wants them to write funnier material, and ends the meeting. In the privacy of his office, Dunwitty tells Delacroix that the material Delacroix's been writing for him seems like it's about white people with black faces. Dunwitty asserts that Delacroix is an "oreo" with his Harvard education, because he won't write a "n----r show."The next day, Delacroix and his assistant Sloan Hopkins (Jada Pinkett Smith) talk. They've decided that Manray is the solution to his problem. Delacroix plans to write a show that will be so "offensive and racist," it will prove his point that the network only wants to see black buffoons on the air. Delacroix simply hopes to be fired, so he can be let go of his contract with CNS. Manray and Womack ask at the receptionist's desk for a "Delapoint" and the men working there tell them to step outside. However, Sloan steps into the lobby, sees what's happening, and escorts Manray and Womack to Delacroix's office. Delacroix explains to them that he has an idea for a television pilot, and they can make money with it. His main request is that Manray changes his name to Mantan, in an apparent homage to black character actor Mantan Moreland.On Sloan's walk home, she runs into her big brother Big Blak Afrika F/K/A Julius (Yasiin Bey). In Sloan's apartment, Julius and Sloan argue about his values, and he tells her to introduce him and his political hip-hop crew, the Mau Maus, to Delacroix.Delacroix has another meeting with Dunwitty. Delacroix proposes that the network start a variety show called "Mantan: The New Millenium Minstrel Show." Delacroix says that new faces are needed for the show, and has Sloan bring in Manray and Womack. The two men, respectively renamed "Mantan" and "Sleep'n Eat," will exhibit a range of stereotypical traits, Delacroix explains. Sloan is opposed to the proceedings, and suggests that there will be protest of the show they are planning. To seal the package, Manray dances atop a table in front of Dunwitty -- who immediately leaves to try to sell the show's concept to his executive bosses.Delacroix, Sloan and another woman hold auditions for the show. The first group of people (The Roots) audition to be the show's house band, The Alabama Porch Monkeys. After they perform, a dancer, a vulgar man shouting "I be smackin' my hoes," and a didgeridoo player all audition. The next hopeful is Honeycutt (Thomas Jefferson Byrd), an actor who bungles Shakespearean quotes and proclaims "N----s is a beautiful thing." Sloan's brother's group, the Mau Maus then do a fiery, confrontational performance; Pierre states via voice over that there is no place for them in his plan.Delacroix looks over a revised script for the show and confronts Dunwitty and his co-writer, Jukka about their alterations to it that even he finds racially offensive. Delacroix says that he won't be responsible for their changes, which Dunwitty says are to make the show funnier. Dunwitty says he knows black people better than Delacroix does, telling him, "Look

Context: A mechanical wave is a disturbance in matter that transfers energy from place to place. A mechanical wave starts when matter is disturbed. An example of a mechanical wave is pictured in Figure 19.1. A drop of water falls into a pond. This disturbs the water in the pond. What happens next? The disturbance travels outward from the drop in all directions. This is the wave. A source of energy is needed to start a mechanical wave. In this case, the energy comes from the falling drop of water. The energy of a mechanical wave can travel only through matter. This matter is called the medium (plural, media). The medium in Figure 19.1 is a liquid the water in the pond. But the medium of a mechanical wave can be any state of matter, including a solid or a gas. Its important to note that particles of matter in the medium dont actually travel along with the wave. Only the energy travels. The particles of the medium just vibrate, or move back-and- forth or up-and-down in one spot, always returning to their original positions. As the particles vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on. There are three types of mechanical waves. They differ in how they travel through a medium. The three types are transverse, longitudinal, and surface waves. All three types are described in detail below. A transverse wave is a wave in which the medium vibrates at right angles to the direction that the wave travels. An example of a transverse wave is a wave in a rope, like the one pictured in Figure 19.2. In this wave, energy is provided by a persons hand moving one end of the rope up and down. The direction of the wave is down the length of the rope away from the persons hand. The rope itself moves up and down as the wave passes through it. You can see a brief video of a transverse wave in a rope at this URL: . To see a transverse wave in slow motion, go to this URL: (0:22). MEDIA Click image to the left or use the URL below. URL: A transverse wave can be characterized by the high and low points reached by particles of the medium as the wave passes through. This is illustrated in Figure 19.3. The high points are called crests, and the low points are called troughs. Another example of transverse waves occurs with earthquakes. The disturbance that causes an earthquake sends transverse waves through underground rocks in all directions from the disturbance. Earthquake waves that travel this way are called secondary, or S, waves. An S wave is illustrated in Figure 19.4. A longitudinal wave is a wave in which the medium vibrates in the same direction that the wave travels. An example of a longitudinal wave is a wave in a spring, like the one in Figure 19.5. In this wave, the energy is provided by a persons hand pushing and pulling the spring. The coils of the spring first crowd closer together and then spread farther apart as the disturbance passes through them. The direction of the wave is down the length of the spring, or the same direction in which the coils move. You can see a video of a longitudinal wave in a spring at this URL: http A longitudinal wave can be characterized by the compressions and rarefactions of the medium. This is illustrated in Figure 19.6. Compressions are the places where the coils are crowded together, and rarefactions are the places where the coils are spread apart. Earthquakes cause longitudinal waves as well as transverse waves. The disturbance that causes an earthquake sends longitudinal waves through underground rocks in all directions from the disturbance. Earthquake waves that travel this way are called primary, or P, waves. They are illustrated in Figure 19.7. A surface wave is a wave that travels along the surface of a medium. It combines a transverse wave and a longitudinal wave. Ocean waves are surface waves. They travel on the surface of the water between the ocean

rarefactions.
