Below is a PV diagram showing a cyclic process for 0.0025 moles of an ideal monatomic gas used in an engine. The direction of the cycle is shown by the arrows on the curve. The temperature does NOT change along segment ca – the process is isothermal from point c to point a. The other 2 sections of curve are graphically vertical and horizontal. (a) (6 points) What volume does the gas occupy at point c? (b) (6 points) What is the temperature at points a, b and c? For parts (c), (d) and (e) indicate whether the heat Q has gone into or out of the gas by referring to the sign, positive or negative, of your answer. (c) (6 points) How much heat went into or out of the gas during segment ab? (d) (6 points) How much heat went into or out of the gas during segment bc? (e) (6 points) How much heat went into or out of the gas during segment ca? (f) (6 points) What is the efficiency of the engine? P (atm) 2.1 a b 0.56++ 0.20 C V(x103) m³

Lexington Company is well known for its high-quality men's shoes. It manufactures all of its products in regional facilities throughout North America, trying to source DM locally when possible. Managers in the production area of one of its plants are beginning to work on next year's first-quarter budgets to ensure they'll have the necessary resources available. Sales are expected to be steady, with 3,500 pairs of shoes (one pair is one unit) budgeted in January. February and March have anticipated sales volume of 3,600 units each, while April will be down slightly to 3,400 units. In order to prevent stock-outs, Lexington's policy requires 15% of the following month's sales be held in ending inventory for all of its shoes. This policy is expected to be met on December 31 of this year. Additional DL and MOH information is as follows. Standard DL time 0.50 hours per unit DL rate $13.00 per DL hour Variable-MOH rate $1.40 per DL hour Fixed-MOH costs Supervisor salaries $4,100 per month Depreciation on plant assets $7,000 per month Insurance and taxes $3,800 per month Required a. Prepare Lexington's production budget for Quarter 1 for this facility. b. Prepare the DL budget for Quarter 1 for this facility. c. Prepare the MOH budget for Quarter 1 for this facility, identifying total MOH costs as well as cash outlay amount for MOH. d. In your work, clearly show the connections among these three budgets, identifying which item(s) from the previous budget(s) is (are) needed in the subsequent budgets. Karen Congo Farmer; Amy Fredin.
