Beatrice and Samantha both get accepted to a MD Program at the University of Alaska and are both studying late at night for STEP 1. Beatrice hates the fact that Samantha keeps getting higher scores than her on Uworld, and decides to fill Samantha's car with 5 m^(3) of water to get back at her. The water "initially" was at 20 degrees celsius, but eventually freezes because of the cold Alaskan air which is at a temperature of -40 degrees celsius. Which causes the water to expand and shatters Samantha's windows as it solidifies. How much heat did Beatrice's water give off as it did this? [Water has a density of 1,000 k(g)/(m^(3))] Group of answer choices -670,000 J -6.2 x 10^(6) J -2.5 x 10^(9) J -9.1 x 10^(8) J

When catechol oxidase was combined with catechol, the amount of benzoquinone produced was very high (5 out of 5). However when catechol oxidase was combined with hydroquinone, very little benzoquinone was produced (1 out of 5). What does that mean about the enzyme? ? the enzyme is not specific because it breaks down catechol and hydroquinone equally ? the enzyme is very specific for the substrate catechol ? the enzyme works better with hydroquinone than catechol ? the enzyme is not specific and will produce benzoquinone regardless of the substrate

If $\cos(x) = \frac{1}{14}$ and $\sin(x) < 0$, find $\tan(2x)$. Hint: Remember, $\tan(t) = \frac{\sin(t)}{\cos(t)}$. You can use that along with sine and cosine identities to figure out! Question Help: Message instructor Submit Question Question 3 If $\csc(x) = -\sqrt{17}$ and $x$ is in QIII, find $\cos(2x)$. Question Help: Message instructor Submit Question Suppose $(1, 2)$ lies on the terminal side of angle $x$ when $x$ is drawn in standard position. Find the following: $\sin(2x)$ $\cos(2x)$ In which quadrant does the terminal side of angle $2x$ lie? Answer 1, 2, 3, or 4, Question Help: Message instructor Submit Question Simplify the expression: Give the answer in exact form. Please reduce any fractions, but the radical can be left alone $\sin\left(2\cos^{-1}\left(\frac{5}{7}\right)\right)$

Rewrite the above program in Python, using while loop instead of for loop, to produce the same output. You should keep the print() statement and the variable names unchanged. See below: Sample Program Output Adding 1 to give the total = 1 Adding 3 to give the total = 4 Adding 5 to give the total = 9 Adding 7 to give the total = 16 Adding 9 to give the total = 25 Adding 11 to give the total = 36 Adding 13 to give the total = 49

A liquid will be heated using a perfectly mixed batch tank that includes a heating coil. The liquid volume in the tank is 2.5 m³, the density of liquid and its heat capacity are 400 kg/m³ and 1.5 kJ/kg°C respectively. A saturated steam is used as heating medium which condenses in the coil. The latent heat of steam is 2100kJ/kg and the heat loss to surroundings is given as $Q_{loss} = 0.7(T - T_s)$ in kW. (T is the liquid temperature and $T_s$ is the ambient temperature in °c) If the temperature of liquid is to be controlled by a PID controller, determine its control parameters using Ziegler-Nichols tuning technique. $G_m(s) = \frac{e^{-0.1s}}{0.5s + 1}$, $G_f(s) = \frac{0.5}{s + 1}$
