Answer:

2.5 * 10^12 Nm-2

Explanation:

Stretching force = 20 * 10^3 N

diameter = 10 * 10^-3 m

extension = 0.2 * 10^-3 m

length of bar = 2m

Young Modulus = stress/strain

stress = Force/Area

Strain = extension/length

Young Modulus = Force/Area/extension/length

But area = πr^2 = 3.142 * (5 *10^-3)^2 = 7.9 * 10^-5 m^2

Stress = 20 * 10^3/7.9 * 10^-5  = 2.5 * 10^8 Nm-2

Strain = 0.2 * 10^-3/2 = 1 * 10^-4

Young Modulus = 2.5 * 10^8/1 * 10^-4  

Young Modulus =  2.5 * 10^12 Nm-2

SVEN [57.7K]

Answer:

Cost-volume-profit analysis.

Explanation:

An important tool in predicting the volume of activity, the costs to be incurred, the sales to be made, and the profit to be earned is cost-volume-profit analysis. It is an important tool in accounting that is used to determine how changes in differing levels of activities such as costs and volume affect a company's operating financial statements, both income and net income. It is also an accounting concept known as the break even analysis.

In order to use this cost-volume-profit analysis, accountants usually make some assumptions and these are;

1. Sales price per unit product is kept constant.

2. Variable costs per unit product are kept constant.

3. Total fixed costs of production are kept constant.

4. All the units produced are sold.

5. The costs accrued are as a result of change in business activities.

6. A company selling more than a product should simply sell in the same mix.

Wimpy Inc. produces and sells a single product. The selling price of the product is $185.00 per unit and its variable cost is $5
Aleonysh [2.5K]

The formula for the calculation is

<u>CM ratio = Unit contribution margin ÷ Unit selling price </u>

The break-even in monthly dollar sales is closest to $578,100

Explanation:

The formula for the calculation is

<u>CM ratio = Unit contribution margin ÷ Unit selling price </u>

<u></u>

<u>Given that </u>

<u>Selling price of the product=</u>$185.00 per unit

variable cost=$55.50 per unit

fixed expense=$404,670 per month

<u></u>

= ($185.00 per unit − $55.50 per unit) ÷ $185.00 per unit

= $129.50 per unit ÷ $185.00 per unit = 0.70

<u>Dollar sales to break even = Fixed expenses ÷ CM ratio </u>

= $404,670 ÷ 0.70

= $578,100

The break-even in monthly dollar sales is closest to $578,100

Wind damage occurs to your car costing $800 to repair. If you have a $500 deductible for collision and full coverage for compreh
Igoryamba

Answer:

$300

Explanation:

Deductible referred to as the amount paid from one's pocket to join the amount of one's loss, while the insurance company balance up the remaining.

The loss which is $800 is a little bit more than deductibles.

Damage=$800

Deductibles=$500

The damages is just $300 more than deductibles.

As stated in the question there is a collision and comprehensive insurance for the driver , therefore the driver will pay $500 from his own pocket.

THE PORTION OF CLAIM THE INSURANCE COMPANY PAY =($800-$500)=$300

$300 will only be received from the company.

In Higher deductibles the premium insurance is reduced in cost.

In lower deductibles there is higher premium but with the cost from one's pocket is low.

Deductible has influence on

one's claim.

Comprehensive insurance is one of automobile insurance,it covers damages or event that occurs to a car that is out of one's control.It covers for replacement or repairment of one's car if damaged by something or to repair bit, other a collision.
