During the first couple weeks of a new flu outbreak, the disease spreads according to the equation $I(t) = 5000e^{0.066t}$, where $I(t)$ is the number of infected people $t$ days after the outbreak was first identified. Find the rate at which the infected population is growing after 12 days and select the appropriate units. Select an answer

Which of the following algorithms best represents a real-world process that involves both selection and repetition, where selection involves decision making and repetition involves doing something over and over again? Group of answer choices Traffic Light Control: Continuously cycle through green, yellow, and red. If a pedestrian button is pressed, extend the red light duration before continuing the cycle. Password Entry System: Prompt the user to enter a password. If the password is incorrect, display an error and allow up to three more attempts. If correct, grant access. Vending Machine Operation: Wait for money to be inserted. If the correct amount is entered, dispense the selected item; otherwise, display an error message and return the money. Coffee Machine Brewing: Heat water, pour it over coffee grounds, and fill the cup. If the cup is full, stop pouring; otherwise, continue until the max level is reached.

Points: 5) The figure shows a central rod (its linear charge density is uniform) that is surrounded by a concentric metal shell in the shape of cylinder and with interior radius R = 0.0900 m. Both shell and rod are very long. The magnitude of the electric field at a point at radius r = 0.0300 m from the rod is 225 N/C. The electric field outside the shell is zero. What is the magnitude of the surface charge density (C/m²) on the outside surface of the shell? Rod Shell A) 4.67 x 10?? B) 0 C) 6.74 x 10?? D) 7.52 x 10?? E) 2.00 x 10??

L-U its 5. Consider three-bar truss shown in Fig. 5. The truss is not subjected to any external load, but due to a manufacturing imperfection, the middle bar is of length $L+\mu$ in its unstressed configuration. The cross-section of each bar is same with area of A, and the Young's modulus is E. Please (1) Find the forces in bars A, B, and C as a function of the magnitude of the manufacturing imperfection, $\mu$. (2) Find the displacement of point O as a function of $\mu$. (3) please propose a method to reduce or even eliminate the force due to the imperfection. (20) B L 60$^\circ$ C Fig.5 Three bar truss
