An older adult patient is admitted to the emergency department (ED) for hypovolemia. After 500 mL of 0.9% NaCl is delivered intravenously over 1 hour, the assessment shows: blood pressure of 167/88 mm Hg, heart rate 110 beats per minute, and crackles bilaterally. What does this indicate? The patient has been properly rehydrated. The patient continues to have a fluid volume deficit. The patient is showing signs of having fluid volume overload. The patient is showing no change in condition.

3. (Electrostatic potential) Consider the electric force field given by \begin{equation} F = \frac{qQ}{\epsilon |r|^3} \mathbf{r} \end{equation} with the charge $Q$ located at the origin and $\mathbf{r} = (x, y, z)$. (a) Verify, whether the function \begin{equation} f(x, y, z) = -\frac{\epsilon qQ}{\sqrt{x^2 + y^2 + z^2}} \end{equation} is a potential function of $\mathbf{F}$. (b) If the charge $q$ moves from the point A to the point B whose distances from the origin are $r_1$ and $r_2$, respectively, find an expression of the work done by the electric force field.

QUESTION 3 (25 MARKS) a) Oscillators are electronic circuits that can generate an output signal without the necessity of an input signal and one of them is called the feedback oscillator. i. Name the two basic components in a feedback oscillator circuit. (CO1: PO1 \textendash{} 2 Marks) ii. If the feedback oscillator has an amplifier component with a voltage gain of 90, identify the necessary attenuation of the feedback circuit in order to sustain oscillation. (CO1: PO1 \textendash{} 2 Marks) iii. Suggest the change required in the feedback oscillator in order for oscillation to begin as the power is turned on. (CO1: PO1 \textendash{} 2 Marks) b) Figure Q3 (b) shows a sinusoidal feedback oscillator called the phase-shift oscillator. Based on this circuit: i. Determine the value of $R_f$ necessary for the circuit to operate as an oscillator. (CO2: PO2 \textendash{} 2 Marks) ii. Determine the frequency of oscillation, $f_r$. (CO2: PO2 \textendash{} 2 Marks) iii. Based on the circuit, modify the oscillator so that it will oscillate at a frequency of 50 kHz. (CO2: PO2 \textendash{} 3 Marks)

A)contextual B)syllogistic C)inductive D)deductive 56)Which of the following is true about the prototype approach to categories and concepts? A)People who have a larger vocabulary develop a more nuanced understanding of concepts B)People think of the most typical example of a category and use that as their prototype C)people develop a prototype (which does not actually exist) by abstracting features of example members of a category D)people learn definitions of concepts by interacting with other people 57)Imagine that it is hot out and you do not have access to an air conditioner. You don't have a fan, but you realize that you can take a newspaper and fold it to form a fan. You have stopped thinking of a newspaper as just something to give you information and started to think of it as a way to cool yourself off. What has happened? A)You used the strategy of working backwards B)You used trial and error C)You overcame functional fixedness D)You used analogical thinking 58)You need to hang a picture on the wall, but you have no hammer. You do have a book, but you only think of a book as an object to read, and not as something to use to pound something into a wall. What are you experiencing? A)analogical thinking B)insight C)trial and error problem solving D)functional fixedness 59)Which type of reasoning always leads to the correct conclusion, as long as the premise is true and good logic is used? A)deductive B)inductive C)contextual D)heuristic 60)What does the typicality effect say with respect to concepts? A)People are more comfortable, and faster, at identifying usual, rather than unusual, examples of a concept B)People develop an image of a concept by using features abstracted from many specific examples of that concept C)People only include typical members in their definition of concepts D)People pay more attention to unusual examples of a concept that stand out from their schema
