Write a script to play two-dimensional Tic-Tac-Toe between two human players who alternate entering their moves on the same computer.

Use a 3-by-3 two-dimensional array. Each player indicates their moves by entering a pair of numbers representing the row and column indices of the square in which they want to place their mark, either an 'X' or an 'O'. When the first player moves, place an 'X' in the specified square. When the second player moves, place an 'O' in the specified square. Each move must be to an empty square. After each move, determine whether the game has been won and whether it’s a draw.

Using the Arizona Wuhan seafood market virus isolate, MN997409.1, run BLAST against the RefSeq Representative genomes (refseq_representative_genomes) database, limiting the search to Viruses (taxid: 10239) in the “Organism” field. From the hits returned, construct a phylogenetic tree (Distance tree of results). Examining the BLAST results and the Distance Tree select all that apply:

a)The non-Wuhan virus genome with the lowest E-value and highest identity is the SARS coronavirus

b)The distance tree suggests the Arizona virus is very different from the reference Wuhan seafood market virus isolate

c)The Distance tree suggests that the Wuhan viruses show similarity to a Bat coronavirus – BM48-31/BGR/2008

d)The White-eye corona virus show a significant hit, but with very low Query coverage

3. What is the total overhead variance for the year when the overhead application rate per machine hour is determined under each of the following options: (a) budgeted output, (b) normal capacity, and (c) practical capacity? Indicate whether each variance is favorable (F) or unfavorable (U). (Do not round intermediate calculations. Round your answers to the nearest whole dollar amount.)

5. What is the Overhead Efficiency Variance (= Variable Overhead Efficiency Variance) for the year when the overhead application rate per machine hour is determined under each of the following options: (a) budgeted output, (b) normal capacity, and (c) practical capacity? Indicate whether each variance is favorable (F) or unfavorable (U).

7. What is the total Overhead Spending Variance for the year under each of the following assumptions regarding the denominator activity level used to set the overhead application rate for the year:

a) budgeted output, (b) normal capacity, and (c) practical capacity? State whether each variance is favorable (F) or unfavorable (U).

8. Break down the Total Overhead Spending Variance (as determined in requirement 7) into: (a) a Fixed Overhead Spending Variance, and

(b) a Variable Overhead Spending Variance. State whether each variance is favorable (F) or unfavorable (U).

Waterways for Chapter 9 (WCP9sum) Summer Waterways Corporation is preparing its budget for the coming year. The first step is to plan for the first quarter of that coming year. Waterways gathered the following information from the managers. Sales: Actual unit sates for November 113,500

Actual unit sales for December 103,100

Expected unit sales for January 114,000

Expected unit sales for February 113,500

Expected unit sales for March 116,000 Expected unit sales for April 126,000

Expected unit sales for May 138,500

Unit selling price $12 Waterways wants to keep 10% of the next month’s unit sales in ending inventory. All sales are on account. 85% of the Accounts Receivable are collected in the month of sale and 15% of the Accounts Receivable are collected in the month after sale. Accounts receivable on December 31 totaled 183,780. Direct Materials: The product uses metal, plastic, and rubber. In total, each unit requires 2 pounds of material at an average cost of 0.75 per pound. Waterways likes to keep 5% of the materials needed for the next month in its ending inventory. Payment for materials is made within 15 days. 50% is paid in the month of purchase and 50% is paid in the month after purchase. Accounts Payable on December totaled $120,595. Raw materials on December 31 totaled 11,295 pounds. Direct Labor: Labor requires 12 minutes per unit for completion and is paid at a rate of $18 per hour. Manufacturing Overhead:

Indirect materials 30 cents per labor hour

Indirect labor 50 cents per labor hour

Utilities 45 cents per labor hour

Maintenance 25 cents per labor hour

Salaries $52,000 per month

Depreciation $16,800 per month

Property taxes $2,675 per month Insurance $2,200 per month

Janitorial $1,800 per month

Selling and Administrative Expenses: Variable selling and administrative cost per unit is $2.40.

Advertising $15,000 per month

Insurance $1,400 per month

Salaries $72,000 per month

Depreciation $2,500 per month

Other fixed costs $3,000 per month

Other Information: The cash balance on December 31 totaled $220,500, but management has decided that it wants to maintain a cash balance of at least $750,000 beginning January 31. Dividends are paid each month at the rate of $2.50 per share for 5,000 shares outstanding. The company has an open line of credit with the First National Bank. The terms of the agreement requires borrowing to be in $1,000 increments at 8% interest. Waterways borrows on the first day of the month and repays on the last day of the month. Reserve repayment, if required, until Waterways can pay the entire amount. A $250,000 equipment purchase is planned for February.

Instructions (Do all parts): Note: All budgets and schedules should be prepared by month for the first quarter (January, February, and March). Round all figures to the nearest dollar. For labor hours round to whole hours.

A bar of length ℓ lies on the ?̂-axis with its center at the origin. A proton sits on the ?̂-axis, a height of ℎ above the center of the bar. The bar carries a total charge of ?, which is distributed uniformly along its area.

a. Find the electric field vector experienced by the proton. I ask that you do solve this integral, though you may use any means necessary to do so (yes, including WolframAlpha).

b. Find the electric field vector experienced by the proton if the bar is infinitely long (but still “centered” on the origin).
