An object is placed 40 cm in front of a converging lens with a focal length of 30 cm. The lens is situated 100 cm in front of a plane mirror. F F do 100 cm A. Determine the location of the first image, $d_i$, formed by the converging lens, expressing your answer in units of cm. B. Determine the location of the image created by the plane mirror from the converging lens's image, $d_i'$. (Hint: you will need to find the location of the image from part A in relation to the mirror.) Again, use units of cm. C. Find the location of the final image created by the system, $d_i''$, formed by the reflected image from part B going back through the lens. (Hint: what is that image's distance from the lens?) Again, express your answer in units of cm. D. Which of the images, if any, are virtual images? There can be more than one correct answer. (Hint: for real images, the light rays need to actually converge at the image location!) a. The first image formed by the lens, $d_i$. b. The image formed by the plane mirror, $d_i'$. c. The final image, $d_i''$. d. None of the above.

If the magnitude of the electric field in air exceeds roughly 3 × 10^6 N/C. the air breaks down and a spark forms. For a two-disk capacitor of radius 92 cm with a gap of 1 mm, what is the maximum charge (plus and minus) that can be placed on the disks without a spark forming (which would permit charge to flow from one disk to the other)? ‡ C

Dog Up! Franks is looking at a new sausage system with an installed cost of $928,200. This cost will be depreciated straight-line to zero over the project's 5-year life, at the end of which the sausage system can be scrapped for $142,800. The sausage system will save the firm $285,600 per year in pretax operating costs, and the system requires an initial investment in net working capital of $66,640. If the tax rate is 25 percent and the discount rate is 11 percent, what is the NPV of this project?

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10.Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for the Miami International Airport. The file miami contains the ratings obtained from the sample of 50 business travelers. (Note: In your answer document, include the output obtained using Excel’s Descriptive Statistics tool) a) Provide a point estimate of the population mean number of ratings. b) At 95%confidence, what is the margin of error? c) What is the 95% confidence interval estimate of the mean?

A strain gage is glued to the outside of a thin-walled cylindrical pressure vessel in the orientation shown below when the internal pressure $p$ is 0. The vessel has a 250 mm diameter and 5 mm wall thickness. The material properties are $E = 200 \text{ GPa}$, $\nu = 0.25$ and yield stress $\sigma_Y = 100 \text{ MPa}$. If the gage reading $\varepsilon_g$ is $100 \times 10^{-6}$: (a) (5%) Express $\varepsilon_g$ in terms of $\sigma_1$, $\sigma_2$, $E$ and $\nu$. (Hint: $\varepsilon(\theta) = \varepsilon_x \cos^2 \theta + \varepsilon_y \sin^2 \theta + \gamma_{xy} \sin \theta \cos \theta$) (b) (5%) Determine the internal pressure $p$ of the vessel. (c) (5%) Determine the increase in radius $\Delta r$ due to the internal pressure. (d) (10%) Draw the Mohr's stress circles (all three), showing the principal stresses and the absolute maximum shear stress. Will the vessel yield according to the maximum-shear-stress criterion?
