    1. A busy commuter train station might seem like a very individualized place. Tens of thousands or hundreds of thousands of strangers flow through with a singular purpose: to get where they need to go.

      It seems at first that theres just a lot of random people going in random directions going to random places but the more we dive into this we will discover the details behind our everyday sights.

    1. form a lattice that minimizes repulsion between like charges while maximizing the attraction between opposite charges. Second, the anion and cation are different entities, and may have completely different volumes.

      Enthalpy of hydration is negative because adding H2O within the lattice neutralizes the repulsion between ions with like charges. Neutralizing the repulsion decreases the potential energy withing the lattice and therefore results in a negative enthalpy.

    1. For a solution with a nonvolatile solute dissolved in a volatile solvent the vapor pressure is due to the solvent

      the vapor pressure of a solution equals the mole fraction of solvent times the vapor pressure of the pure solvent, so adding a nonvolatile solute lowers vapor pressure.

    1. Earth orbiting satellites, control and monitoring stations across the Earth, and GPS receivers owned by individuals.

      These 3 types help with the global postioning system and are 3 parts that are importnant for thier own reasons

    1. Latitude and longitude comprises a grid system of lines encircling the globe and is used to determine the locations of points on the earth. Lines of latitude, also called parallels, run east - west. Latitude lines always run parallel to each other, and hence, they are always an equal distance apart. Latitude lines never converge or cross.

      Lattitude and longitude both have huge factors in geography used for being important for thier own reasons

    1. A model is simply a representation of a real thing. You have seen and used models in the past, like a globe which is a model of the earth. Geographers construct models to analyze geographic processes because the real object of study may be too large to examine, the processes which created it operate over too long of a time frame, or experimentation might actually harm or destroy it.

      Models help show the real world. It helps geographers understand more and explain and predict what will happen

    1. Large scale maps, such as 1:24000 scale maps show a smaller area in great detail. Small scale maps have the least detail but show large areas.

      Large scale maps and small scale maps are key in geography due to the different factors because some show bigger or smaller based on what scale

    2. An isoline is a line that connects points of equal value. For instance, the brown contour lines on United States topographic map connect points of equal elevation.

      Isolines are very important because they help show patterns and sapatial data

    3. The information collected to create a map is called spatial data. Any object or characteristic that has a location can be considered spatial data. Maps can depict two kinds of data. Qualitative map data is in the form of a quality and expresses the presence or absence of the subject on a map, like the kind of vegetation present occupying a region. Quantitative map data is expressed as a numerical value, like elevation in meters, or temperature is degrees celsius.

      There are many types of data and they all come together to help create these maps in geography. They each have thier own functions

    1. Newton’s third law has practical uses in analyzing the origin of forces and understanding which forces are external to a system.

      Force need to be actions for it too work

    2. body exerts a force on a second body,

      When the first body and the second body both have equal magnitude and opposite direction and the force start itself exerts.

    3. net external force is in the same direction as acceleration

      This is when an external force is being added and their going in the same type of direction as accleleration.

    4. net external force is in the same direction as acceleration

      This is when an external force is being added and their going in the same type of direction as accleleration.

    5. (which is a net external force) for there to be any change in velocity (either a change in magnitude or direction).

      The external force is change inn velocity meaning time or displacement or acceleration were to change the place of the initially velocity.

    6. Bridges, buildings, fences, roads, swimming pools, towers and many more constructions can only be created to be reliable with a proper understanding of Newton’s laws.

      More stuff like building that are used in houses and building these was made by netwons laws

    7. irplanes, boats, cars, cannons, elevators, rockets, satellites, space shuttles, trains, trucks, and many more.

      NEwton laws were discoved by each other these and many more weapons that were made.

    8. A body at rest remains at rest,

      This mean that IV because that the beginning of where we started and this is gonna remain the same at a constant velocity needs to be move by external force

    1. The corresponding velocity versus time graph should indicate a negative value in this range because the slope of the line in the position versus time graph is negative.

      But x-axis let it stays negative and the slope of the line in h position.

    2. Because the slope is constant on the position versus time graph, the value on the y-axis is a constant on the velocity versus time graph.

      WHen heading to the Y-axis remainds constanst.

    3. by an upward sloping line,

      Slope is going to be heading upward meaning it head postive. Heading in a constasnt way which is the same way and let the VI in constasnt way.

    4. 30-minute round trip to the store, the total distance traveled is 6 km

      Take around 30 mins for total distance to be 6 km and the as was 2km/h and the displace was zero and so was av.

    1. velocity remains constant, the position changes at a constant rate.

      In the first image when the journey increase the velocity mains constanst and the posittion changes at constant rate

    2. To find displacement, we use the equation Δx=xf−x0Δx=xf−x0\Delta x=x_{\mathrm{f}}-x_{0}. This is straightforward since the initial and final positions are given.

      When finding the displacement of both equation we used this

    3. xxx-axis so that + means to the right and − means to the left for displacements, velocities, and accelerations.

      A displacement holds 2km and a positive sign going to the right. B displacement is -1.5km going to the left.

    4. For velocity and acceleration we are also considering time. Velocity is the change in displacement over a period of time.

      1) Displacement & Speed & Time and Acceleration are considered velocity quantity.

    1. Are you a “traditional” or “returning” student? List an important advantage you have as a result of being in this classification: __________________________________________________________________

      I am a traditional student and one advantage is to finish my work on time and to keep up with it

    2. __________________________________________________________________

      I am a traditional student, an advantage id have is have a higher chance of remembering things I learned in high school compared to a returning student.

    3. __________________________________________________________________

      I am a traditional student, the advantage is that I don't have a job so after school I go to the town library and study and finish work.

    4. __________________________________________________________________

      I am a traditional student, the advantage is I don't have a job so after practice I'm able to direct my attention straight to my work.

    1. predation

      I heard that because humans over hunted some wolfs that it eventually lead to a river changing its path. Here is the situation I am talking about from google: "human hunting of wolves led to a trophic cascade where the absence of wolves in places like Yellowstone National Park allowed elk populations to boom, overgrazing riverbanks, leading to increased erosion and degraded river systems" Has there been more than one occasion somthing like this has happened and if so has this been studied extensively?

    1. Take composer Hans Zimmer for example. Zimmer has composed scores for more than 150 films, working with dozens of filmmakers. And he understands how music can support and enhance a narrative theme, creating a cohesive whole. In his work with Christopher Nolan, The Dark Knight (2008), Inception (2010), Interstellar (2014), his compositions explore the recurring theme of time:

      i think this is important to understand that music can create emotion and a better movie for the audeince and the plot of the characters.

    2. It’s just for us in the audience. If the kids in the water could hear the theme from JAWS they’d get out of the damn water and we wouldn’t have a movie to watch. It is also always recorded after the final edit of the picture is complete.

      i agree the non diegetic music is onyl for the audience to understand and the actors have to pretend they don't hear the music or it would ruin the film . Jaws is a perfect example of this.

    3. If the music is not a part of the world of the film or tv series, and only the audience can hear it, then it is non-diegetic music. Too abstract? Okay, if a song is playing on a radio in a scene, and the characters are dancing to it, then it is diegetic. But if scary, high-pitched violins start playing as the Final Girl considers going down into the basement to see if the killer is down there (and we all know the killer is down there because those damn violins are playing even though she can’t hear them!), then it is non-diegetic.

      these are some important points to keep in mind is music in the film is heard by the audience and the actors then it is considers diegetic music now if the jusic can only be heard by the audience then it is considered non-diegetic this is all new information to me as well i never this phenomenon had a name to it.

    4. As the use of sound in cinema has become more and more sophisticated over the last century, music has remained central to how filmmakers communicate effectively (and sometimes not so effectively) with an audience. At its best, music can draw us into a cinematic experience, immersing us in a series of authentic, emotional moments

      I agree i think music can be used in various different ways throughout a film not only in the beginning but in scary scenes or sad plots.

    5. Silence can punctuate an emotional moment or put us in the headspace of a character in a way that visuals alone simply cannot.

      silence in a shot can describe a eerie feeling especially in horror movies or emotional shots that are suppose to oimpact the audience.

    6. Now sound can appear to be coming from in front, behind, below or above audiences, creating a 3-D aural experience.

      this makes since because movie theaters are so loud and you can hear everything that has been adding in the sound mixers.

    7. As the century rolled on, newer, hi-fidelity sound reproduction found its way into theaters allowing for more sophisticated surround sound systems, and consequently, more work for sound mixers to create an immersive experience for audiences.

      i think sound mixing rising the tension and emotions of the audience watching the film.

    8. sound mix can be objectively calibrated according to a precise decibel level, or degree of loudness, for each layer of sound. Dialogue within a certain acceptable range of loudness, music in its range, sound effects in theirs. Basic math. On the other hand, the mix can and should be a subjective process, actual humans in a room making adjustments based on the feel of each shot and scene

      this tells me that sound mixing can affect the audios level of loudness or softness. This can be used in intense scenes or emotion romance shots.

    9. , known as a J-cut, or by continuing the audio of the previous shot into the first few seconds of the next, known as an L-cut. This technique is most noticeable in transitions between radically different scenes

      this movie is a great example of J=cut it adds the audio before showing the next clip in the movie this can be used in many different genres comedy and horror.

    10. . Many of these sounds already exist in extensive sound libraries, pre-recorded by sound technicians and made available for editors. But many of them must be created to match exactly what the audience will see on screen. That’s where foley artists come in.

      this is interesting to know that nature, birds, and evrononmetal sounds can be made by a foley artist or are pre recorded in places like the library which leads me to another point the liberty is a great places to record sounds because it is quiet and background noises won't interfere with the audio being recorded.

    11. It involves creating all of the sounds that weren’t recorded on set to make up the rich soundscape of the finished motion picture. In that sense, it is literally more “creative” than picture editing!

      I find this type of editing unique to the production of filmmaking i onced wanted something like this in the production of hollywood movies. not only is this creative but this allows films to perfect the audio for a shot.

    1. Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias.

      I believe that this practice is great, because it will give for accuarate unbiased results.

    1. 2. Summarize the information contained in the chemical equation below. How would this reaction be classified? CaCl2(aq) + Na2CO3(aq)→CaCO3(s) + 2NaCl(aq)

      The equation CaCl₂(aq) + Na₂CO₃(aq) → CaCO₃(s) + 2NaCl(aq) shows that an aqueous solution of calcium chloride reacts with an aqueous solution of sodium carbonate to produce a solid precipitate of calcium carbonate and an aqueous solution of sodium chloride. This is a double displacement reaction that can be further classified as a precipitation reaction because it forms an insoluble solid.
