MORE Answered by sebassandin Expert-Verified Answer Answer Answer: $ K(2000 K)=0.722 $ $ K(3000 K)=23.5 $ Explanation: Hello, In this case, in terms of the Gibbs free energy of the given reaction, the equilibrium constant is computed as shown below: $ K=\exp \left(-\frac{\Delta G}{R T}\right) $ In such a way, since the given Gibbs correspond to formation of $ X $, they will equal the Gibbs free energy of those reactions. Thus, at each temperature we obtain: \[ \begin{array}{l} K(2000 K)=\exp \left(-\frac{5410 \mathrm{~J} / \mathrm{mol}}{8.314 J /(\text { mol*K }) * 2000 K}\right) \\ K(2000 K)=0.722 \end{array} \] \[ K(3000 K)=\exp \left(-\frac{-52480 \mathrm{~J} / \mathrm{mol}}{8.314 \mathrm{~J} /(\mathrm{mol} * K) * 3000 \mathrm{~K}}\right) \] $ K(3000 K)=23.5 $ Best regards. 0 1 5.0

A radio receives electromagnetic waveforms via the antenna as some type of modulated carrier wave. While the carrier wave is in the hundreds-to-thousands of kilohertz, the base band of the audio signal is in 20-20,000 Hz range. Sometimes, noise may be coupled into the system in the base band, and this noise must be filtered out. Consider a system that picks up an undesired frequency of 8761 Hz. As an engineer, you are asked to design an RLC filter to eliminate the undesired frequency, while minimally affecting the desired audio frequency band. Consider the following circuit: Notch Filter Configuration Using R, L, C $v_i(t)$ R $+V_R-$ $i(t)$ $+\ C V_C$ $v_o(t)$ $+\ L V_L$ 1. Determine the following: (a) Find the frequency domain transfer function, $H(j\omega)$. (b) Determine the value of $\omega$ (in terms of R, L, and C) when $|H(j\omega)| = 0$. (c) Determine the value of $|H(j\omega)|$ for $\omega = 0$ and $\omega = \infty$.

Identifying Analogical Arguments Analogical arguments are arguments based on comparison. They use the perceived similarities between two things to infer some further similarity that has yet to be observed. So, in other words, because two things are similar in one or more respects, what is true of one thing is argued to be true of another thing. Question 1 (1 point) "Explaining a joke is like dissecting a frog. They both lead to understanding, and they both die in the process." - E.B. White Determine if an analogy is present. If an analogy is present, determine whether it is illustrative or argumentative. Question 1 options: No analogy Illustrative analogy Argumentative analogy Question 2 (1 point) "Choosing not to exercise may be foolish and hazardous to your health. But, it doesnâ€™t harm anyone except yourself. In the same way, choosing not to wear a seatbelt is also foolish and hazardous to your health. Thus, it probably doesnâ€™t harm anyone but yourself." Determine if an analogy is present. If an analogy is present, determine whether it is illustrative or argumentative. Question 2 options: No analogy Illustrative analogy Argumentative analogy Question 3 (1 point) "Life is like a box of chocolates; you never know what youâ€™re going to get." - Forrest Gump Determine if an analogy is present. If an analogy is present, determine whether it is illustrative or argumentative. Question 3 options: No analogy Illustrative analogy Argumentative analogy Question 4 (1 point) "Most things true of me are also true of Jones. We are both alike in general behavior, nervous system, etc. And I generally feel pain when showing outward pain behavior. So, it's likely that Jones does, too." Determine if an analogy is present. If an analogy is present, determine whether it is illustrative or argumentative. Question 4 options: No analogy Illustrative analogy Argumentative analogy Question 5 (1 point) â€œThe economy is like an oil tanker: It takes a lot to get going, but it takes a lot to slow it down.â€ Determine if an analogy is present. If an analogy is present, determine whether it is illustrative or argumentative. Question 5 options: No analogy Illustrative analogy Argumentative analogy
