A factory has a buffer with a capacity of 4 m3 for temporarily storing waste produced by the factory. Each week the factory produces k m3 waste with a probability pk, where p0=1/8, p1=1/2, p2=1/4 and p3=1/8. If the amount of waste produced in one week exceeds the remaining capacity of the buffer, the excess is specially removed at a cost of 30 per m3. At the end of each week there is a regular opportunity to remove the waste from the storage at a fixed cost of 25 and a variable cost of 5 per m3. The following policy is used. If at the end of the week the storage buffer contains more than 2 m3, the buffer is emptied; otherwise, no waste is removed. Determine the ling-run average cost per week. You need to define the states and the transition probability matrix well first.

1. An aluminum ring of radius 5.00 cm and resistance 3.00 × 10–4 O is placed on top of a long air-core solenoid with 1 000 turns per meter and radius 3.00 cm, as shown in the sketch below. Over the area of the end of the solenoid, assume that the axial component of the field produced by the solenoid is half as strong as at the center of the solenoid. Assume the solenoid produces negligible field outside its cross-sectional area. The current in the solenoid is increasing at a rate of 270 A/s. (a) What is the induced current in the ring? At the center of the ring, what are (b) the magnitude and (c) the direction of the magnetic field produced by the induced current in the ring?

2. The square loop in the sketch shown below is made of wires with total series resistance 10.0 O. It is placed in a uniform 0.100-T magnetic field directed perpendicularly into the plane of the paper. The loop, which is hinged at each corner, is pulled as shown until the separation between points A and B is 3.00 m. If this process takes 0.100 s, what is the average current generated in the loop? What is the direction of the current?

3. In the sketch shown below, the bar magnet is moved toward the loop. Is Va – Vb positive, negative, or zero? Explain.

When Patey Pontoons issued 4% bonds on January 1, 2018, with a face amount of $580,000, the market yield for bonds of similar risk and maturity was 5%. The bonds mature December 31, 2021 (4 years). Interest is paid semiannually on June 30 and December 31. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)Required: 5. What is the amount related to the bonds that Patey will report in its balance sheet at December 31, 2018?
6. What is the amount related to the bonds that Patey will report in its income statement for the year ended December 31, 2018? (Ignore income taxes.)
7. Prepare the appropriate journal entries at maturity on December 31, 2021.
