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

cos(x) csc(x) = cot(x).

For f(x) = 3x+2,  g(x) = 5-2x, (

Why was the Constitutional Convention called?

Suppose members of the Republican Party prefer that a Republican be elected president in the next election, but they disagree about which particular member of the party would be the best choice. The problem facing members of the Republican Party is best described as a/an 

Public opinion polls generally indicate that most Americans support high levels of government services and benefits, though they are opposed to raising taxes to pay for them. This pair of stylized facts is most indicative of a/an
