The pressure in an axisymmetric extension around a sphere of radius $R$ is $P(r, \theta) = -5\mu \alpha \left(\frac{R}{r}\right)^3 (3\cos^2(\theta) - 1)$. where $\mu$ and $\alpha$ are constants. Compute the component of the pressure gradient at the of the sphere.

In some scenarios, the pressure is a solution of the equation \frac{\partial^2 p}{\partial x^2} + \frac{\partial^2 p}{\partial y^2} = 0. $^1$Henry Darcy was a 19th century French engineer. 3. Show by substitution that $p = -x - 2y$ is a solution of the pressure equation above and calculate the corresponding velocity $v$ assuming $\lambda = 1$. Find and plot the contours of $p$ and add arrows indicating the direction of the flow. This plot should be sketched by hand. Briefly describe this flow in words.

A home-based software company offers projects on multiple expertise. As the business grows, company wants to create online presence. After approval of front-end design, the conflict arises at back-end programming. To display the expertise (in languages) of programmers, some argue that tree like structure with most-in-demand languages as parent nodes is acceptable. Some are inclined to sort the abovementioned tree and then display it. Remaining votes are in favor of both strategies. You are designated to create a visual representation of both techniques. Following are the total expertise offered by the company. \begin{itemize} \item Java \item C# \item C \item C++ \item Go \item R \item Swift \item PHP \end{itemize} Note: Demand of each language is determined by sum of their ASCII code values.
