In a machine that temperature changes from 20 ∘C∘C up to 120 ∘C∘C a tungsten wire filament 15.0 cmcm  long with a diameter of 1.30 mmmm  will be used. The wire will carry  14.0 AA   at all temperatures ( Resistivity of tungsten at 20 ∘C∘C is 5.25×10−8Ω⋅m5.25×10−8Ω⋅m , the temperature coefficient of resistivity at 20 ∘C∘C is 0.0045 ∘C−1∘C−1 )

Calculate the maximum electric field in this filament?

Calculate the resistance of the filament  with that field?

Calculate the maximum potential drop over the full length of the filament?

16-35 The following are various changes in audit circumstances.

Audit Circumstance

1. The client began experiencing an increase in returns due to product changes that resulted in increased defects.

2. You found several pricing errors in your substantive tests of transactions for sales.

3. In performing substantive tests of transactions for cash receipts, you found that receipts were promptly recorded in customer accounts, but there were delays in depositing the receipts at the bank.

4. The client entered into a new loan agreement with the bank. Accounts receivable are pledged as collateral for the loan.

5. The client did not reconcile the accounts receivable subsidiary records with the accounts receivable balance in the general ledger on a regular basis.

6. Substantive analytical procedures indicated a significant slowing in accounts receivable turnover.

7. The client entered into sales contracts with new customers that differ from the client’s standard sales contracts.

8. The client had a significant increase in sales near year end.

9. Accounts receivable confirmations were ineffective due to a very low response rate in the prior-year audit.

Match each change in audit circumstance with the most likely test of details of balances response. Each response is used once.

a. Expand testing of sales returns after year end and compare the level of returns with the prior year.

b. Send positive confirmations that include requests for information on side agreements and special terms.

c. Increase the number of accounts traced from the accounts receivable trial balance to the accounts receivable subsidiary records.

d. Expand the review of cash receipts after year end to evaluate the collectability of accounts receivable.

e. Increase the sample size for sales cutoff testing for sales recorded before year end.

f. Send a confirmation to the bank confirming amounts pledged as collateral under loan agreements.

g. Increase the sample size for positive confirmation of accounts receivable.

h. While at the client’s premises at year end, obtain information on the last few cash receipts at year end for cash receipts cutoff testing.

i. Perform alternative procedures to test the existence and accuracy of accounts receivable instead of sending positive confirmations.

There are 4 Basic Financial Statements: Income Statement, Balance Sheet, Statement of Changes in Stockholders/Owner’s Equity,...

There are 4 Basic Financial Statements: Income Statement, Balance Sheet, Statement of Changes in Stockholders/Owner’s Equity, and Statement of Cash Flows. The Statement of Cash Flows typically receives the least amount of attention in Accounting textbooks. Further, the news typically focuses on ‘Net Income’ and ‘Quarterly Earnings.’ Also, reference is also made to items on the Balance Sheet. For example, technology companies can be a risky investment because despite their high earnings, there may be very little in the way of tangible assets supporting their business. The Statement of Changes in Stockholder’s Equity really reports only the change in ‘book value’ of the company. A company may have total Stockholder’s Equity of $50 million and 500,000 shares outstanding. The book value of the share is $100 but the stock may be trading in the market anywhere from $85 to $120 per share. Is it wrong to report the stock at book value? What can people learn about stewardship from the Statement of Cash Flows? What insights does it provide that people can’t learn from the other 3 Financial Statements? What are your thoughts on this from a Christian perspective?

Individuals experience various mood states or emotions at varying times every day, both subtle changes and obvious changes, that can result in attitude alternations with both negative and positive effects and impair or facilitate performance. The connections in the brain between emotion and memory have been particularly interesting to researchers given that neural networks that are activated by mood states are linked with neural networks that process basic perceptual functions such as word processing. Dr. Siebert has conducted a number of research experiments inducing various mood states through the use of music and then studying the effects of mood on lexical processing. In this study, higher scores on the Mood State measure reflect higher levels of lexical processing. The average Mood State score is μ = 3. (Dr. Pennie S. Siebert)

To examine changes in teaching self-efficacy, 10 teachers were measured on their self-efficacy toward teaching at the beginning of their teaching career and at the end of their first year and third years of teaching. The teaching self-efficacy scale ranged from 0 to 100 with higher scores reflecting greater teaching self-efficacy. The data are shown here.

A. Conduct a one-factor repeated measures ANOVA to determine mean differences across time, using alpha = .05.

B. Then, use the Bonferroni method to detect if and/or where the differences are among the time points.

Give necessary tables/figures for each.
