The figure shows, in cross section, several conductors that carry currents through the plane of the figure. The currents have the magnitudes $I_1 = 4.4$ A, $I_2 = 5.7$ A, and $I_3 = 2.5$ A, and the directions shown. Four paths, labeled a through d, are shown. (Figure 1) What is the line integral $\oint \vec{B} \cdot d\vec{l}$ for the path d? The integral involves going around the path in the counterclockwise direction. Express your answer using two significant figures.

The bob of a simple plane pendulum of mass $m_0$ and length $l_0$ is connected to two small blocks, one of mass $m_1$ by a dashpot, and the other of mass $m_2$ by a spring. The dashpot (with dashpot constant $c$) and spring (with spring constant $k$) are both ideal and massless. The spring is unstreched when the pendulum is vertical and the masses are at the positions shown. An external force $F(t)$ acts on $m_2$. Assume small motions such that the dashpot and the spring remain almost horizontal at all times. Note that gravity acts. i. How many degrees of freedom does the system have? Pick generalized coordinates and describe the generalized coordinates clearly. ii. Find the equation(s) of motion using Lagrangian approach.

Question Completion Status: Question 1 A flat surface of a furnace losses heat to the surrounding that has a temperature T = 45°C and convective heat transfer coefficient of 12 W/(m².K). The area of this surface is 10 m². The surface temperature is maintained at 326.85°C and its spectral emissivity is given as: $\begin{cases} \epsilon_1 = 0.2 & 0 \leq \lambda < 5 \text{µm} \\ \epsilon_2 = 0.9 & 5 \text{µm} \leq \lambda < 10 \text{µm} \\ \epsilon_3 = 0.6 & 10 \text{µm} \leq \lambda < 15 \text{µm} \\ \epsilon_4 = 0.1 & 15 \text{µm} \leq \lambda < \infty \end{cases}$ Take the Stefan-Boltzmann constant, $\sigma = 5.67 \times 10^{-8} \text{W}/(\text{m}^2.\text{K}^4)$. Determine the total rate of heat losses from the surface in kW. Thereafter, choose the correct value from the values provided below. $\circ$a. 42.3 $\circ$b. 114.3 $\circ$c. 72.0 $\circ$d.

Powell Company owns an 80% interest in Sauter, Inc. On January 1, 20X1, Sauter issued $400,000 of 10-year, 12% bonds at a premium of $25,000. On December 31, 20X5, 5 years after the original issuance, Powell purchased all of the outstanding bonds for $390,000. Both firms use the straight-line method of amortization. What is the gain on retirement on the 20X5 consolidated income statement?
