Andreas93 [3]3 years ago

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.

Exercise 13-17 Swifty Company has been operating for several years, and on December 31, 2017, presented the following balance sh
mixer [17]

Answer:

(a) Current ratio = 2.746

(b) Acid-test ratio = 1.423

(c) Debt to assets ratio = 47.48%  

(d) Return on assets = 6.15%

Explanation:

For Balance Sheet, pleased see attached file.

Current Ratio = Current Asset / Current Liabilities

Current Ratio = 212,800 / 77,500

Current Ratio = 2.746

Acid-Test Ratio = (Current Assets – Inventories) / Current Liabilities

Acid-Test Ratio = (212,800 – 102,500) / 77,500

Acid-Test Ratio = 1.423

Debt to Asset ratio = (Total Liabilities / Total Assets)*100

Debt to Asset ratio = (205,500 / 432,800)*100

Debt to Asset ratio = 47.48%

ROA = (Net Income / Total Assets)*100

ROA = (26,600 / 432,800)*100

ROA = 6.15%

The Current Ratio is a liquidity measure that shows the ratio between current asset and current liabilities. It tells how many dollars of the current asset are per dollar of current debts, that gives an idea of the company`s ability to perform its debts.    

The Quick Ratio is also a liquidity indicator, but using its most liquid assets, to pay its current liabilities at maturity. The inventory, although it is a current asset, is not considered, since it cannot be converted into cash in a very short term.

The difference between the Quick Ratio and the Current Ratio, implies that while both are measures of the company's ability to pay its debts, the quick ratio also tells how much the company depends on its inventory to get that objective.

The Debt to Assets ratio is a financial ratio that shows how much of a company assets is owed to its creditors.  

ROA is a financial indicator that gives an idea as to how efficient a company's management is at using its assets to generate earnings, by determining how profitable a company is relative to its total assets.

Which of the following is false? Economists who advocate discretionary monetary policy argue that it is more likely to achieve t
just olya [345]

Answer: None of the above

Explanation:

All of the above are correct.

For option A, Economists who advocate discretionary monetary policy do indeed believe that the monetary authority using this policy is more flexible to shape the best monetary policy to the existing circumstances.

Option B is also correct because Crowding out occurs when the government increases investment by borrowing which leaves less money for the private sector to borrow so they spend less. The government spent money here yet the private sector did not spend less so it is Zero Crowing out.

Option C by option B's explanation holds true because the entire amount the Government increased by was denied the private sector.

Option D is also true as not all Economists prefer rule-based monetary policy to discretionary monetary policy.

They are all true.
