At least one of the answers above is NOT correct. 2 of the questions remain unanswered. A rectangular storage container with an open top is to have a volume of 10 m$^3$. The length of its base is twice the width. Material for the base costs $3 per m$^2$. Material for the sides costs $25.6 per m$^2$. Find the dimensions of the container which will minimize cost and the minimum cost. base length = m base width = m height = m minimum cost = $

A company purchased a three-acre tract of land for a building site for $250,000. On the land was a building with an appraised value of $119,000. The company demolished the old building at a cost of $12,300, but was able to sell scrap from the building for $1,650. The cost of title insurance was $910 and attorney fees for reviewing the contract were $460. Property taxes paid were $3,800, of which $240 covered the period subsequent to the purchase date. The capitalized cost of the land is: Multiple Choice A. $265,580. B. $132,150. C. $267,230. D. $267,470.

In his Introduction Jackson discusses attempts to measure the mass of the photon. $m_\gamma \approx 0$ as best we can tell. For all practical measurements so far the photon is massless. This does not have to be in principle. Jackson mentions a Yukawa shape for the scalar potential, $V_Y(r)$. Suppose there is a particle with an electric charge $q$. The Yukawa potential would be $V_Y(r) = \frac{q}{4\pi\epsilon_0} \frac{exp(-\alpha m_\gamma r)}{r}$. (1) Suppose we use the usual connection between the electric potential and the electric field. In this case, $\vec{E}_Y = -\frac{\partial V_Y}{\partial r} \hat{r}$. With this electric field, $\vec{E}_Y$, imagine a charge $q$ surrounded by a sphere of radius $R$. What would be the total electric flux, $\int_S \vec{E}_Y \cdot \hat{n} da$ through the sphere, where $\hat{n}$ is the unit normal vector for the surface element $da$? What is the implication for Gauss's law if the photon mass is non zero?

3. What conditions led to the Haymarket Square riots in 1886? What connection does Robert Koehler's The Strike have to the riots? What role do the women figures have in the painting and how is class distinction emphasized? What was the purpose of the Police Monument following the riots and how is the Haymarket Monument a reaction not only to the Police monument but also to the historical role of women in sculpture? What message does this monument send to viewers? What makes the Statue of Liberty a politically neutral work and how does it appeal to conservatives and radicals at the same time? Why was the statue given to the United States by France?
