Hi!

Option A is correct.

In cooking, convection is the phenomena that causes molecules with a higher energy at the bottom of a container to travel upwards, and the molecules at the top with a lower energy to sink to the bottom and replace them.

Mechanical convection describes this phenomena as a result of the application of an external force.

This phenomena is restricted to substances that are in liquid, or gaseous state, as molecules of a substance in solid state have a very restricted movement.

Hence, options B, C and D are incorrect.

Hope this helps!

One of two alternatives will be selected to reduce flood damage in a rural community in central Arizona. The estimates associate

pochemuha

Answer:

Since the incremental B/C of 58.21 is less greater 1, it implies that the alternative that should be selected is Channel.

Explanation:

The alternative that should be selected can be determined using the Benefit-Cost (B/C) analysis as follows:

Incremental B/C = [Incremental Flood damage savings * ((1 + r)^-3 + (1 + r)^-9 + ((1 + r)^-18)] / [Incremental initial cost + (Incremental Annual Maintenance cost * ((1 - (1 / (1 + r))^n) / r))] ............... (1)

Where:

Incremental initial cost = Channel initial cost - Retention pond initial cost = $1,500,000 - $880,000 = $620,000

Incremental Annual Maintenance cost = Channel Annual Maintenance - Retention pond Annual Maintenance = $30,000 - $92,000 = -$62,000

Incremental flood damage savings = Channel Incremental flood damage savings - Retention pond incremental flood damage savings = $625,000 - $200,000 = $425,000

r = Discount rate = 8%, or 0.08

n = number of years = 20

Substituting all the relevant values into equation (1), we have:

Incremental B/C = [425000 * ((1+0.08)^-3 + (1+0.08)^-9 + (1+0.08)^-18)] / [$620,000 - ($62,000 * ((1 - (1 / (1 + 0.08))^20) / 0.08))]

Incremental B/C = $656,340.35 / $11,274.86

Incremental B/C = 58.2127235166936

Rounding to 2 decimal places, we have:

Incremental B/C = 58.21

Since the incremental B/C of 58.21 is less greater 1, it implies that the alternative that should be selected is Channel.

A T-bill quote sheet has 60-day T-bill quotes with a 4.95 ask and a 4.89 bid. If the bill has a $10,000 face value, an investor

In-s [12.5K]

Answer:The correct answer is a). $9,918.50

Explanation: In selling, the investor will use the bid price of $4.89 alongside the face value of the bill.

That is to say, the face value * (1-(bid price * no. of days)/days in a year) = 10000 * (1-(0.0489*60)/360) = $9,918.50

Prepare Job-Order Cost Sheets, Predetermined Overhead Rate, Ending Balance of WIP, Finished Goods, and COGS At the beginning of

vova2212 [387]

Answer and Explanation:

1. The computation of overhead rate based on direct labor cost is shown below:-

Overhead rate = Overhead applied × 100 ÷ Direct labor cost

= 888 × 100 ÷ 1,200

= 74%

2. The Preparation of job-order cost sheet for the four jobs is shown below:

Particulars Job 86 Job 87 Job 88 Job 89

Beginning balance $6,888 $6,820

Direct materials $3,000 $7,000 $2,100 $1,500

Direct labor $800 $6,000 $900 $500

Applied overhead

is 74% of direct labor $592 $4,440 $666 $370

Total $11,280 $24,260 $3,666 $2,370

3. The computation of ending balances of Work in Process and Finished Goods is shown below:-

Work in process of Job 88 = $3,666

Finished goods = Total of Job 86 + Total of Job 89

= $11,280 + $2,370

= $13,650

4. The computation of the Cost of Goods Sold for March is shown below:-

Cost of goods sold is

= Job 87

= $24,260

Motown records was created by Berry Gordy Jr. who is an American record executive, record producer, song writer, film producer and television producer. The Motown record company played a very important role in the racial integration of popular music as an African-American owned label that got crossover success. Motown was the most successful record label of soul music. Motown producers believed "resolutely" in KISS principle (keep it simple stupid) and they used Pop production techniques such as the use of orchestral string sections, charted horn sections, and carefully arranged support vocals. Complex arrangements and melismatic vocal riffs were avoided.
