Stop-and-frisk was a problematic policing strategy because: Stop-and-frisk was a problematic policing strategy because: It was deemed to be unconstitutional It was usually based on racist assumptions and created a climate of suspicion It was highly inefficient in terms of generating arrests Actually, stop-and-frisk was great; it was community policing that caused a variety of major problems

(1 point) Explain whether (or not) the following series of read requests will have a lower miss rate on a 32 KiB two-way set associative cache with LRU replacement than on the cache in part (a). The sequence 0, 32768, 0, 32768, 0, 32768,
Under the Harmonized Tariff Schedule, all members of the WTO charge the same rate of duty upon the import of the same or similar products. True or false?
An electron is accelerated from rest through a potential difference that has a magnitude of $2.40 \times 10^7$ V. The mass of the electron is $9.11 \times 10^{-31}$ kg, and the negative charge of the electron has a magnitude of $1.60 \times 10^{-19}$ C. (a) What is the relativistic kinetic energy (in joules) of the electron? (b) What is the speed of the electron? Express your answer as a multiple of $c$, the speed of light in a vacuum.
1 MVA is a three-phase dislocation pole synchronous generator of 3.3 KV. The parameters of this generator are as follows: nd90 = xnd01 = x R = 0 pu (Note: RA is omitted) This generator transfers 0.8 pu active power to the grid with a 0.8 lagging power factor. In this case, V = 1.0 pu I = 0.8 pu cos(θ) = 0.8 a.) Find the internal power factor angle (angle between EA and IA), the Power Angle (angle between EA and VO), and the value of EA (opposite EMC). b.) Since the maximum value of the idle operating voltage is 2 pu (use this value in this option), what are the maximum values of the reactive forces it can attract from the network? c.) Since the maximum value of the idle operating voltage is 2 pu (use this value in this option), what is the maximum active power that this generator can give to the network?
4. (20pt) $f(x) = (x + \frac{\pi}{2})\sin(x)$, with $0 \le x \le \pi$ a) Sketch this function for the defined range b) Determine the Fourier series for $f(x)$ c) Determine the alternative Fourier series with complex coefficients. d) Verify that your results in b) and c) are consistent.
7. Applying the point rule at point a in the circuit below, (A) $I_1 + I_2 = -I_3$ (B) $I_1 + I_2 = I_3$ (C) $I_1 + I_3 = I_2$ (D) $I_1 = I_2 + I_3$ 8. Applying the loop rule to the loop a, b, c, d, a (A) $2V + 3\Omega I_1 - 3I_2 - 5V = 0$ (B) $2V - 3\Omega I_1 + 3\Omega I_2 - 5V = 0$ (C) $-2V - 3\Omega I_1 - 3\Omega I_2 + 5V = 0$
Explain the reason why so many other industrialized nations provide far more social support than the US? What about when it comes to communities and families and their lack of social support compared to others? Explain thoroughly. Must be in your own words.
Assume that you calculated operating leverage factor to be 3. How would you interpret that number?
