A patient with a 15-year history of Parkinson’s Disease has been taking Levodopa/Carbidopa for 12 years. What will the therapist likely note during this patient’s “off” times?

A company is about to install a Linux server to provide e‑commerce services to external users. The manager of the production support team wants to allow six (6) employees to have full access to this server so they can perform appropriate support and maintenance activities. Explain how the manager should allow these employees to have full access to the server using best practice as discussed in this course. Also explain why this best practice is better than alternative ways to provide full access.

In a typical Linux system there is a file named exam1.pdf .  The ACL for that file is shown as “–rw-r—–” . In plain English explain the access to that file for users of the system.  Your answer must cover all users of the system.

A user starts a typical Linux system in VMware Workstation Pro 17. The first screen he sees shows “vmware” in large text, with some smaller text but the screen changes too quickly to read it. The next screen begins with “GNU GRUB”. Explain the process that is showing this screen, and what the process will do if the user does not interact with it.

A student has just installed a Debian system. She wants to compile some C code, so she decides to install the package gcc. Show the command(s) she should use to install that package, using best practice as discussed in a lecture in this course.

A typical computer has one solid-state drive.  It has a CD/DVD drive and there is a CD‑ROM in the drive.  It has two USB ports, one of which has a USB device inserted into it.  It has an Ethernet network port connected to a local area network (LAN). Which device will be used to boot this computer?

See the previous question. The user wants to change some settings in the process that shows the first screen, but is unable to press the required key quickly enough. Explain what the user should do to easily access the function that allows him to change the required settings.

See the previous question. The student decides she no longer needs to compile C code, but now needs to compile some C++ code. She installs the package g++.  She then issues a command to remove the package gcc.  The output shows that both gcc and g++ will be removed. Explain why g++ will also be removed if she proceeds to remove gcc.

Problem 4 (30 Points – Bernoulli’s Equation). In the fountain shown in Figure P.4, water exits from the ground with a velocity of 7.5 m/s and reaches a height h above the ground before falling again. The water source is 4 m below the ground. Water is collected below the ground through a 6 cm diameter circular pipe and the diameter of the circular opening on the ground is 8 cm. Consider the flow to be incompressible, steady, and frictionless. For water, consider ρ = 998 kg/m3. Determine: (a) The height, h. (b )The mass flow rate in the fountain. (c) The velocity and the absolute pressure at the location where water is collected below the ground.

Problem 3 (20 Points – Mass Conservation). At a piping junction, a water stream at 20°C is divided as shown in Figure P.3. Water enters the inlet at section (1) with a flow rate of 20 gal/min. In section (2), the average velocity is 2.5 m/s, and in section (3), a showerhead is attached to the outlet. There are 100 holes with an equal diameter of 1 mm at the showerhead opening. Assuming uniform shower flow and circular cross-section for all the pipes, estimate the exit velocity from each hole of the showerhead jets. Consider, 1 gal = 3.79 L. Figure P.3
