Using the video, the assigned course reading (specifically Introduction to Epidemiology, and the video How Nurses Use Epidemiology) consider the following:How did John Snow use the web of causation related to cholera? Why do you believe that Snow was successful or unsuccessful in establishing a cause? Remember to cite evidence to support your position. It can be from the resources within the course.Select a disease/outbreak to research. Discuss the level of the disease and type of transmission. As you review the selected disease/outbreak, describe the investigative strategies used, and explain how these aligned (or did not align) with strategies used by John Snow. Use one scholarly journal to support your research.

(Estimated time allowance: 7 minutes) The following information is obtained from the financial statements of a corporation. Click heree for formatted shell excel file. Market: Expected return is 12%. Risk-free rate is 1.38. The tax rate is 40%. Common stock: Each share of stock is currently trading for $52. Last year, the company paid a dividend of $5.31 per share. The dividend is expected to grow by 6 percent per year indefinitely. The stock has a beta is 1.20. The corporation has 600,000 shares outstanding. What is the average cost of common equity (Re) for this company? For your answer, round to the nearest .1%. Do not use the % sign in your answer. For example, if the answer is 9.23%, enter your answer as 9.2; Do not enter it as .0923, 0.0923, or 9.23%.

Head On Collision Points: 20 A mass $M_2$=5.90 kg slides on a surface with negligible friction and collides head-on with mass $M_1$. $v_0$ $M_2$ $M_1$ $v_2$ $M_2$ $M_1$ After Before Before the collision, $M_2$ has a speed $v_0$=5.50 m/s and $M_1$ is at rest. After the collision, $M_2$ has speed $v_2$=2.90 m/s and $M_1$ has speed $v_1$=3.50 m/s, both in the initial direction of $M_2$ (see figure). Calculate the mass of $M_1$. Submit Answer Tries 0/100 For the collision above, select the one best answer for the statement below. The collision is inelastic. Submit Answer Tries 0/100

4. A 1kg mass is attached to a spring with constant $k = 2 \frac{N}{m}$. The system is initially at rest at the equilibrium position in a medium with a damping factor of $\gamma = 2 \frac{N s}{m}$. At $t = 5s$ the system receives a unit impulse. Write the equation of motion and solve it. Sketch the graph of the solution and calculate $\lim_{t \to \infty} y(t)$.
