A flask is charged with 1.800 atm of N2O4(g)and 1.00 atm of NO2(g) at 250 ∘C , and the following equilibrium is achieved: N2O4(g)⇌2NO2(g) After equilibrium is reached, the partial pressure of NO2 is 0.513 atm . What is the equilibrium partial pressure of N2O4?

What fallacy does the following argument commit? Cathy says it's okay to remove hearts from patients who have been declared dead by cardiac standards even if it might be possible to start their hearts again using CPR. She must want doctors to kill patients willy-nilly and harvest their organs! Group of answer choices Red herring Ad hominem Straw man Genetic fallacy

Texts: You throw up a rock with an initial velocity of 4.0 m/s from a 23.0 m cliff. a) What is the maximum height (relative to the base of the cliff) the rock reaches? b) How fast was the rock traveling the instant it struck the ground? c) How long does it take the rock until it hits the ground, from the instant you threw it?
4. Find the general solution of the following inhomogeneous systems. Use either eigenvector decomposi-tion or undetermined coefficients method. These problems can be solved by hand, but you can also use technology to assist you at any stage. When using technology always report on what function you use. \begin{align*} (a) \frac{d}{dt} \begin{bmatrix} x_1\\x_2 \end{bmatrix} &= \begin{bmatrix} -2 & 5\\5 & -2 \end{bmatrix} \begin{bmatrix} x_1\\x_2 \end{bmatrix} + \begin{bmatrix} 3e^{-2t} \\e^{-2t} \end{bmatrix} \\ (b) \frac{d}{dt} \begin{bmatrix} x_1\\x_2 \end{bmatrix} &= \begin{bmatrix} 2 & -1\\3 & -2 \end{bmatrix} \begin{bmatrix} x_1\\x_2 \end{bmatrix} + \begin{bmatrix} \cos 3t\\4 \end{bmatrix} \end{align*}

(1 point) Find an equation of the plane that contains the points \(P(-2, 1, -4)\), \(Q(2, 0, -9)\), and \(R(0, 4, -5)\).
Por una superficie horizontal no conductora rueda sin deslizar un anillo de masa m = 2 g con velocidad constante, que posee una distribucion de cargas uniforme. Tras conectar un campo magnetico uniforme horizontal B = 0.2 T perpendicularmente al plano del anillo, la fuerza de presion del anillo sobre la superficie disminuye a la mitad. Determina la velocidad con que rueda el anillo si su carga total es q = 2 µc ($2 \times 10^{-6}$ c) Ov = 0 Ov = $2 \times 10^2$ m/s Ov = $24.5 \times 10^3$ m/s Ov = 24 m/s Ov = $2.4 \times 10^{-3}$ m/s Ov = 245 m/s Ov = $24.5 \times 10^6$ m/s Ov = $24.5 \times 10^3$ m/s Ov = $24.5 \times 10^5$ m/s Ov = 21 m/s
