Essay on Method of Limits

These parts make up the sound waves and they travel through a medium which is the material that a wave energy travels through. On page 10 in Activity 2 we had to fill out the table on how to make a louder sound and we learned that to have a louder sound the compressions have to be larger and to increase the frequency the compressions also had to be larger. When we did the activity with the slinkies this was the case because when we had more compressions the sound was louder and the frequency increased. In Activity 1 on page 4 we learned that sound intensity is how much sound energy passes through a certain area in a certain amount of time as it spreads out from the source. Decibels are a unit of measure that indicates the relative intensity of a sound. In Activity 1 on page 5 when we were looking at the table it showed us that as the sound intensity increases the decibel increases because the decibel measured how intense the sound was. According to the chart on page 4 the decibels at a quiet library is 40 dB and the relative intensity is 1000, however if the noise source is some explosions then the decibels is 160 and the relative intensity is

“involves a subject conducting a certain task, in this case recalling a series of numbers, while listening to different kinds of background music. If sound exhibits acoustical variations, or what Perham calls an "acute changing-state," performance is impaired. Steady-state sounds with little acoustical variation don't impair performance nearly as much.”(Cutler).

When I came back and asked the rest of the people in the room if they noticed what was going on, they said they did not realize I was doing it intentionally. They told me that they thought I could not hear the phone since the music I was listening to was louder than the volume of the ringtone. This section of the experiment surprised me, to realize if my phone rang (and if it was something vital) and if truly I could not hear it, the people in the room could have not told me for the first or second time.

This essay will reflect my thoughts on chapter 9. In brief this chapter deals with how the ears allow us to be able to hear and process sound. When I first think of sound I think of the frequency. This makes me think of songs that I listen too in order to determine it 's a high frequency or a low frequency. I 'll be able to determine the amount of hertz that are in songs on the radio. I do feel that it would be hard to determine because most of that music is reordered, hearing people sing a cappella would be easier to determine the amount of hertz present. I know what hertz are, but I 'm still not sure how they are actually determined? Are they sounds just determined by our brain if we have unimpaired hearing. How would someone like my brother with a whole in his ear be able to determine frequency?

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

5. For the following set of scores, compute the range, the unbiased and the biased standard deviations, and the variance. Do the exercise by hand.

Range (X) = Highest Value of Weight – Lowest value of weight = 8.2-7.4 = 0.8

The Supreme Court has been left without a majority vote and is dysfunctional. The current fiasco that is happening in Washington with the court being weakened by other branches of the government is an example of the Supreme Court being diminished by political battling. Therefore, term limits are necessary because they would reduce political fighting, younger judges are more in touch and terms will allow more diversity on the court.

My favorite AP Calculus AB topic is solving limits. This is because limits are fairly simple to solve. AP Calculus AB was extremely difficult for me, so I was happy to find a topic that was somewhat easy for me to understand. I know that a limit is the value that a function or sequence approaches as the input or index approaches some x-value. To solve most limits, I had to use six basic properties of limits: the sum rule, the difference rule, the product rule, the constant multiple rule, the quotient rule, and power rule. Sometimes I had to use substitution, factor the limit first, use the conjugate method, or simplify the complex fraction in the limit. To solve limits involving infinity, I had to look at the highest degree of the numerator and denominator. If the degree of the numerator is equal to the degree of the denominator, the limit is the lead coefficient ratio. If the degree of the numerator is greater than the degree of the denominator, the limit does not exist (DNE), ± ∞. If the degree of the numerator is less than the degree of the denominator. Understanding how to solve limits pleased me. I liked solving limits because I did not have much difficulty doing it.

Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20,000Hz.

To understand these ideas, you first have to have a basic understanding of how sound is created.

We hypothesize that the students will be able to identify the third sound and connect be able to connect it to the sound that it belongs to (either the first one or the second one) proving we have categorical perception does allow us to categorize sounds. The cut out point should be somewhere between 40 and 60 VOT.

Introduction Emergence agitation (EA) was fi rst described in the literature in the early 1960s, where children anesthetized with ether, cyclopropane, or ketamine undergoing tonsillectomy, thyroidectomy, and circumcision experienced crying, thrashing, and disorientation during emergence from anesthesia [1]. EA in children, associated with general anesthesia with the new highly insoluble volatile agents, sevofl urane and desfl urane, has been well described [2]. Th e use of sevofl urane even for anesthesia of short duration continues to be complicated by this phenomenon [3]. Th is has been attributed, in part, to rapid emergence not allowing for acclimation to a strange environment [4].

It is within this framework that I consider important to study the way in which sound is

Based on the chart, the mean was calculated by adding up the sum of the list and divide 18, which the number of the total listed prices. The mean is 135,000, which mean the average of the listed price. Secondly, the median was calculated by listing the number in numerical order from lowest to highest and located the number in the middle 126,000. The median represents the middle number of the listed price. After calculating the median I located the minimum and maximum based the lowest and highest data, which are 48,000 and 338,000. These represent the range of the listed price. Lastly, I used the formula to get the
