Water flows through a horizontal pipe. In a wide section (A1 = 0.0600 m^2), the speed is 3.00 m/s and the (absolute) pressure is 250 000 Pa. In a narrow section, the area is A2 = 0.0200 m^2. Assuming water density is 1 000 kg/m^3, what is the pressure in the narrow section?

4.00 moles of an ideal gas are held at a temperature of 400 K and a volume of 0.0500 m^3. What is the pressure of the gas? (R = 8.314 J/(mol·K)).

A 3.00 kg mass is swung in a vertical circle of radius 1.50 m. If its speed at the very bottom of the circle is 6.00 m/s, what is the tension in the string? (Assume g = 9.80 m/s^2).

A stone is thrown horizontally off a cliff with an initial speed of 20.0 m/s. It hits the ground 60.0 m horizontally away from the base. How high is the cliff? (Assume g = 9.80 m/s^2).

Please reflect on the following FEAP and what you learned about The Learning Environment in this course… To maintain a student-centered learning environment that is safe, organized, equitable, flexible, inclusive, and collaborative, the effective educator consistently: a. Organizes, allocates, and manages the resources of time, space, and attention; b. Manages individual and class behaviors through a well-planned management system; c. Conveys high expectations to all students; d. Respects students’ cultural linguistic and family background; e. Models clear, acceptable oral and written communication skills; f. Maintains a climate of openness, inquiry, fairness and support; g. Integrates current information and communication technologies; h. Adapts the learning environment to accommodate the differing needs and diversity of students; and i. Utilizes current and emerging assistive technologies that enable students to participate in high-quality communication interactions and achieve their educational goals.

  What was the answer to the research question/article purpose? Remember, if we don’t answer our research question/purpose, then our research did not fulfill its intended goal. Remember, if there is more than one purpose, there will be more than one answer for the results section! And, there may be more parts to the results than just 1 answer, even if there’s only 1 purpose statement. Often there are many answers that we need to provide here to earn full credit. This is probably going to be the longest answer for this assignment. [8 points – approximately 3-6 sentences]
