Assume the full-scale value of the analog input voltage to a particular ADC is $10 \mathrm{~V}$. a. If this is a 3-bit device, what is the resolution of the output? b. If this is an 8-bit device, what is its resolution? c. Make a general comment about the relationship between the number of bits and the resolution of an ADC.

Assume that the given figure represents a model of the auxiliary output port of a car. The output current is $i=1 \mathrm{~A}$ when $v=$ $0 \mathrm{~V}$. The output voltage is $v=12 \mathrm{~V}$ when a $20-\Omega$ resistor is connected between the terminals Suppose you wanted to charge a $12-\mathrm{V}$ battery by connecting the battery at the port. How much current would the port deliver to the battery?

Titration of the $\mathrm{I}_2$ produced from $0.1045 \mathrm{~g}$ of primary standard $\mathrm{KIO}_3$ required $30.72 \mathrm{~mL}$ of sodium thiosulfate.

$$\begin{gathered} \mathrm{IO}_3^{-}+5 \mathrm{I}^{-}+6 \mathrm{H}^{+} \rightarrow 3 \mathrm{I}_2+3 \mathrm{H}_2 \mathrm{O} \\ \mathrm{I}_2+2 \mathrm{~S}_2 \mathrm{O}_3^{2-} \rightarrow 2 \mathrm{I}^{-}+\mathrm{S}_4 \mathrm{O}_6^{2-} \end{gathered}$$

What is the output of the following program segment?

int temp[5];

for (int i = 0; i < 5; i++)
    temp[i] = static_cast<int>(pow(i, 2.0));
    
for (int i = 0; i < 5; i++)
    cout << temp[i] << " ";
    
temp[4] = temp[3] * temp[2];
temp[3] = temp[4] - temp[2];
temp[0] = temp[5] / temp[1];

for (int i = 0; i < 5; i++)
    cout << temp[i] << " ";
cout << endl;

To learn how nested for loops work, do a walk-through of the following program segments and determine, in each case, the exact output.

const int M = 10;
const int N = 10;
int i, j;
for (i = 1; i <= M; i++)
{
     for (j = 1; j <= N; j++)
         cout << setw(3) << M * (i - 1) + j;
     cout << endl;
}

Suppose you reflect a triangle in Quadrant I over the y-axis, then translate the image 2 units left and 3 units down. Is there a single transformation that maps the preimage onto the image? Explain your reasoning.

The circuit shown as above is an example of a low-pass filter. (Assume that the output is connected to a load that draws only an insignificant amount of current.) If the input voltage is given by $V_{\text {in }}=$ $V_{\text {in peak }} \cos \omega t$, verify that the output voltage is $V_{\text {out }}=V_{\mathrm{L}} \cos (\omega t-\delta)$ where $V_{\mathrm{L}}=V_{\text {in poak }} / \sqrt{1+(\omega R C)^2}$.

Write the rule shown In each table.

$$\begin{matrix} \text{Input} & \text{.} & \text{Output}\\ \text{2} & \text{?} & \text{10}\\ \text{4} & \text{?} & \text{20}\\ \text{6} & \text{?} & \text{30}\\ \text{8} & \text{?} & \text{40}\\ \end{matrix}$$

In 1866 Texas cowhands used the Chisholm Trail to drive cattle north to the railroads in Kansas. The average rate r that the cattle could be moved along the trail was 11 miles per day.

Make a table of input t and output d for t = 7,14, and 28 . Then graph the data.

I have a power supply that produces an output of $25 \mathrm{~V}$ dc. I want three regulated outputs of approximately $15 \mathrm{~V}, 15.7 \mathrm{~V}$, and $16.4 \mathrm{~V}$. Show me a circuit that will produce these outputs.

Sketch and label the figure. Mark the figures.Trapezoid ZOID with $\overline{Z O} \| \overline{I D}$

Suppose that the input is 38 35 71 14 -1. What is the output of the following code? Assume all variables are properly declared.

cin >> sum;
cin >> num;
for (j = 1; j <= 3; j++)
{
    cin >> num;
    sum = sum + num;
}
cout << "Sum = " << sum << endl;

Which of the following elements occur naturally as diatomic molecules: He, O, F, I, Ne?

Let A, B, and C be $n \times n$ matrices. (a) Suppose that $\mathbf{A B}=\mathbf{O}_{n}$, and A is nonsingular. What must B be? (b) If $\mathbf{A B}=\mathbf{I}_{n}$, is it possible for AC to equal $\mathbf{O}_{n}$ if $\mathbf{C} \neq \mathbf{O}_{n}$? Why or why not?
