Enthalpy is defined as the measure of energy in a thermodynamic system. The value of enthalpy is considered to be equal to the internal energy of the system and the product of pressure and volume. Calorimeter is usually used to obtain the value of enthalpy of a system. 
A coffee cup calorimeter is an effective way of measuring the enthalpy of a system because it is a constant pressure calorimeter. This means that, the heat that is measured in a coffee cup calorimeter is equivalent to the change in enthalpy; also its use result in little or no volume change to the system involved.

Jensen Co. expects to pay €50,000 in one month for its imports from France. It also expects to receive €200,000 for its exports
Julli [10]

Answer:

-$5,873

Explanation:

For computation of maximum one month loss in dollars first we need to find out the net exposure and maximum one month loss in percentage which is shown below:-

Net exposure = Received amount - Paid amount

= €200,000 - €50,000

= €150,000

Maximum one - month loss in Percentage = Next month percentage - (Alpha × Euro percentage)

= 2% - (1.96 × 2.5%)

= -2.9%

Maximum one - month loss in Dollars = Net exposure × Current spot rate of the euro × Maximum one - month loss in Percentage

= €150,000 × $1.35 × (-0.029)

= -$5,873

Vedmedyk [2.9K]

<u>A. According to the constant dividend growth​ model, the value of the firm depends on the current dividend​ level, divided by the equity cost of capital plus the grow rate.</u>

This is the false statement.

<u>Explanation</u>:

The fair value of stock can be calculated using the dividend growth model. While calculating the value of the stock, the growth of the dividends should be considered either in a stable rate or at a different rate during the period at hand.

The dividend growth model is also known as a <u>valuation model</u> as it is used to achieve the value of the stock.

Equity cost is the cost that the firm owes to the equity investors to compensate the risk of their investment.

PRO FORMA INCOME STATEMENT Austin Grocers recently reported the following 2016 income statement (in millions of dollars): Sales
padilas [110]

Answer:

Net income = $169.2

Growth in dividend = 76.25%

Explanation:

The projected figures are as below:

Sales = $700 x (1 + 15%) = $805 <em>(15% increase in sales)</em>

Operating costs including depreciation = $805 x 60% = $483 <em>(60% of sales)</em>

Interest expense = 40 <em>(remain constant)</em>

EBIT = Sales - Operating costs including depreciation = $805 - $483 = $322

EBT = EBIT - Interest expense = $322 - $40 = $282

Net income = EBT x (1 - Tax rate) = $282 x (1 - 40$) = $169.2

Dividend = Net income x Dividend payout ratio = $169.2 x (32/96) = $56.4

Growth in dividend = $56.4/$32 = 76.25%
