Researchers doing a study comparing time spent on social media and time spent on studying randomly sampled 200 students at a major university. They found that students in the sample spent an average of 2.2 hours per day on social media and an average of 1.8 hours per day on studying. If all the students at the university in fact spent 2.3 hours per day on studying, with a standard deviation of 2 hours, the shape of the sampling distribution of the sample average time spent studying is:

PROBLEM A 8m tall fence runs parallel to the side of a house 3m away. What is the length of the shortest ladder that clears the fence and reaches the house? Assume that the vertical wall of the house and the horizontal ground have infinite extent. Use calculus to solve the problem. Hints: You will need the following concepts - Pythagoras theorem, similar triangles, derivatives (chain rule and product rule). Criteria for passing the project: \begin{itemize} \item The diagram depicting the problem is well drawn \item The mathematical formulations are well structured. The variables are properly defined. \item The solution approach uses the principles of calculus and is self explanatory without missing steps. \item The final solution is correct with appropriate units. \end{itemize}

ME 301 Homework 5 Due: Wednesday, October 2, 2019 1. A piston-cylinder with a volume of 0.25 m^3 holds 1 kg of air (R = 0.287 kJ/kgK) at a temperature of 100°C. How much heat is added to the piston-cylinder? 2. A piston-cylinder with a volume of 0.25 m^3 holds 1 kg of H2O at a pressure of 100 kPa. Heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. How much heat is added to the piston-cylinder? 3. Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature by 400°C from an initial temperature of T = 27°C and pressure of P = 1 MPa. The process is an isobaric process. Find the final pressure, P_b, and the heat transfer to the air. 4. A balloon with a volume of 0.5 m^3 is filled with air at a temperature of 20°C and a pressure of 100 kPa. If the balloon is well insulated and atmospheric pressure is 100 kPa, how much electrical power will the resistance heater need to dissipate to heat up the balloon? 5. Air in a closed system undergoes an isothermal process from an initial state at temperature T = 100°C and pressure P = 500 kPa to a final state at pressure P = 100 kPa. If there is 1 kg of air in the system, find: a) the initial volume, V, b) the work done, W_2, and c) the heat transfer, Q_2. 6. Saturated water vapor is cooled and condensed into saturated liquid water in an isobaric process at a pressure of 100 kPa. Find: a) the heat transferred per kg of H2O, q, and b) the work done per kg of H2O, w. 7. Two pressurized containers are connected with a valve. Before the valve is opened, container A contains m = 2 kg of steam at a pressure of P = 1 MPa and a temperature of T = 300°C, while container B contains m = 3 kg of a saturated liquid-vapor mixture at a temperature T = 150°C and quality x = 0.5. The valve is opened and the two containers are allowed to come to thermal and mechanical equilibrium at a pressure of P = 300 kPa. Find: a) the temperature of the final state, T_s, and b) the heat transferred from the tanks, Q. 8. Copper rods are to be heated in a furnace from an initial temperature of T = 20°C to a final temperature of T = 200°C. The process calls for 60 steel rods per minute to be heated. Each copper rod has a radius of 0.5 cm and a length of 10 cm. What is the rate that heat must be transferred from the furnace to the copper rods? Assume the density and specific heat of the balls are given to be p = 8900 kg/m^3 and c = 0.393 kJ/kg°C.
