Suppose the magnetic field of the preceding problem oscillates with time according to $B = B _ { 0 } \sin \omega t$. What then is the emf induced in the loop when its trailing side is a distance d from the right edge of the magnetic field region?

Product structure is declared as follows:

struct Product
{
    char description[50];   // Product Description
    int partNum;            // Part Number
    double cost;            // Product Cost
};

Write a loop that will display the contents of the entire array you created in Question 11.4.

Find the work which is done by the force field $\boldsymbol{\Phi}(x, y)=\left(x^2+y^2\right)(\mathbf{i}+\mathbf{j})$ around the loop $(x, y)$ $=(\cos t, \sin t), 0 \leqslant t \leqslant 2 \pi$.

Fish ________________ systems pump blood in a single loop through a heart with two main chambers.

A principal node is a. a closed path or loop where the algebraic sum of the voltages must equal zero. b. the simplest possible closed path around a circuit. c. a junction where branch currents can combine or divide. d. none of the above.

The magnetic flux through a 25-loop wire coil changes by $2.6 \times 10^{-4} \mathrm{T} \cdot \mathrm{m}^{2}$ and produces an induced emf of 1.7 V. How much time is required for this change in magnetic flux?

In a program you need to store the populations of $12$ countries.

a. Define two arrays that may be used in parallel to store the names of the countries and their populations.

b. Write a loop that uses these arrays to print each country’s name and its population.n 3(a).

A square loop 24.0 cm on a side has a resistance of $5.20 \Omega .$ It is initially in a 0.665-T magnetic field, with its plane perpendicular to $\overrightarrow{\mathbf{B}}$, but is removed from the field in 40.0 ms. Calculate the electric energy dissipated in this process.

Exercises refer to the following algorithm segment. For each positive integer n, let

$$a_n$$

be the number of iterations of the while loop. while (n>0), n :=n div 2, end while. Trace the action of this algorithm segment on n when the initial value of n is 27.

A charged particle moving around a circular orbit at uniform speed has a centripetal acceleration and therefore produces a radiation field. However, a uniform current flowing around the circular loop does not produce a radiation field. Is this a contradiction? Explain.

Write a program with a loop that lets the user enter a series of integers. The user should enter −99 to signal the end of the series. After all the numbers have been entered, the program should display the largest and smallest numbers entered.

An inverting amplifier must provide an input impedance of approximately 10 $k \Omega$ and a nominal gain of 4. If the op amp exhibits an open-loop gain of 1000 and an output impedance of 1 $k \Omega$, determine the gain error.

Show that the statement $m \geq x$ for all $x \in\left\{x_{1}, x_{2}, \ldots, x_{i}\right\}$ is a loop invariant for the loop in the following pseudocode segment. Preconditions: $\left\{x_{1}, x_{2}, \ldots, x_{n}\right\} \subseteq \mathbf{Z}$

$$\begin{array}{l}{i \leftarrow 1} \\ {m \leftarrow x_{1}} \\ {\text { while } i<n \text { do }}\end{array} \\ \begin{array}{l} \ulcorner {i \leftarrow i+1} \\ {\text { if } x_{i}>m \text { then }} \\ \llcorner {m \leftarrow x_{i}}\end{array}$$

The feedback current amplifier in Fig. P10.26 utilizes an op amp with an input differential resistance $R_{i d}$, an open-loop gain $\mu$, and an output resistance $r_o$. The output current $I_o$ that is delivered to the load resistance $R_L$ is sensed by the feedback network composed of the two resistances $R_M$ and $R_F$, and a fraction $I_f$ is fed back to the amplifier input node. Find expressions for $A \equiv I_o / I_i$,$\beta \equiv I_f / I_o$, and $A_f \equiv I_o / I_s$, assuming that the feedback causes the voltage at the input node to be near ground. If the loop gain is large, what does the closed-loop current gain become? State precisely the condition under which this is obtained. For $\mu=10^4 \mathrm{~V} / \mathrm{V}, R_{\text {id }}=1 \mathrm{M} \Omega, r_o=100 \Omega$, $R_L=10 \mathrm{k} \Omega, R_M=100 \Omega$, and $R_F=10 \mathrm{k} \Omega$, find $A$, $\beta$, and $A_f$.
