“The particles in the pulse travel from one place to another.” This sentence is wrong about the propagation of a pulse because particles do not travel in a pulse. They just stay in one place moving up and down and interact with each other. Because the particles are moving, energy are transferred through the medium from one place to another.

-“The wavelength is 0.20 s.” This is wrong because wavelength’s unit is meter and it measures the distance between two adjacent locations in the disturbance, not the time one particle takes to finish one vibration.
-“The wave continues to travel for 0.20 s before stopping.” This sentence is wrong because period does not measure the time the medium takes to stop moving. Period is the measure of the time one particle takes to complete one vibration and start to repeat it again. We do not know if one particle will stop after one vibration.

It does not indicate the longitudinal speed of the wave or the speed of one particle (vibrational speed). We cannot have the transverse speed of the particles since they do not move transversally.
-“The wave disturbance travels 300 m for each wavelength.” The speed of the wave does not determine how long the wave disturbance travels for each wavelength. We do not have enough information to determine that.
20.5
-“The wave continues to travel for 4.0 m before stopping.” This sentence is wrong because we do not know if the wave will stop after it travelled for 4.0 m. The wave can continues moving after 4.0 m and the wavelength measures the distance between two adjacent locations in the disturbance.
-“The period of the wave is 4.0 m.” This sentence is wrong because period’s unit is second(s) or minute(s), etc. Period does not measure distance, it measures the time one particle takes to complete one vibration so it cannot be in meter.
In longitudinal waves the object doesn’t exactly follow the waves fully instead the object moves in a back and forth motion while the waves continues to move forward through the object. While in transverse waves the object doesn’t follow the waves as well and just moves up and down in the same position.
The subject with type first and type second diabetes who does not receive standard care, comply with the prescriptions or poorly controlled metabolism regarded by the test physician.
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.

Spectrum sensing: Cognitive radio technology will enable the users to determine which portions of the spectrum is available and detect the presence of licensed users when a user operates in a licensed band. A CR user can be allocated to only an unused portion of the spectrum. Therefore, a CR user should monitor the available spectrum bands, and then detect spectrum holes. Spectrum sensing is a basic functionality in CR networks, and hence it is closely related to other spectrum management functions as well as layering protocols to provide information on spectrum availability.
Graph 2 represents that patient A has a much lower initial glucose concentration than patient B. The glucose concentration of patient A reached its maximum in the first 30 minutes, this is due to the quick release of insulin from the body. Whereas, patient B had a slower reaction to releasing insulin which allowed for longer time to be taken for glucose concentration to reach its maximum. The sudden decrease of the glucose concentration in patient A displays the conversion of glucose molecules being stored as energy. In comparison, the gradual change of the slope show that as patient B releases small amount of insulin, it takes more time for glucose molecules to be converted as energy. It can be concluded that patient B has diabetes as the
Premise: A team of three contestants answer a series seven questions by attempting to diffuse seven bombs before they explode. On each question, one contestant will have a certain amount of time to clip the wires that lead to the correct answers on each bomb. Each teammate must answer at least one question in the game. Successfully diffusing a bomb adds the money at stake for the question to the team bank. If a contestant clips a wire which leads to an incorrect answer or if time expires, the bomb explodes, sliming the contestant with a mystery substance (maple syrup, pesto, tomato sauce, etc.), and eliminates them from the game without adding any money to the team bank. Here’s how the game is structured for each bomb:
A more detailed implementation description is shown in Figure~\ref{fig:block_HHC_shaw}. The components of the harmonic amplitude vector $Y$ are the Fourier coefficients of the measured vibration at the frequency $\omega$. The Fourier coefficients are obtained by integrating the demodulated vibration signal over one sampling period $T^s$. As for the control adjustments $\Delta u_c$ and $\Delta u_s$, they are obtained as the product of the components $Y$, and the inverse of the control response matrix $T$. The control adjustments are sampled and added to the control signal amplitudes of the previous time step, generating the current control amplitude vector $U_k$. The controller output is obtained by summing the modulated components of the control

DSDV is a proactive, hop-by-hop distance vector routing protocol where the routing table is maintained by each and every network node. The routing table consists of all the nodes required to reach destination also including the nodes to which packets are not sent. The routing table is kept updated at every time after each entry. In order to avoid the routing loops, DSDV uses the concept of sequence numbers to maintain the originality of route at all times. For the network in figure. 1 below, the routing table for node A can be seen in table. 1 which contains information about all possible paths reachable by node A, along with the next hop, number of hops and sequence number.
The Wave, by Todd Strasser, is a novel about a school-wide experiment about how the German people could have followed Hitler and the Nazis. Two characters Laurie Saunders and Robert Billings showed a dramatic change in their actions, popularity, and their emotions from the Wave experiment. Together they had a huge impact at their school, Gordon High.
Doubts of the the wave erupted for Laurie because of the insight her mother gave her about the wave. Lauries mother explained how no one will be able to express themselves or be independent while participating in the experiment. She got lost in the unity part of the wave and didn't see what was really happening until it was pointed out by her
As time passes, the other teachers and a handful of students become more troubled with the effects of the Wave (the expression
The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:
