Which of the following would cause an increase in a country's aggregate demand?

Pressure with Two Liquids, Hg and Water. An open test tube at 293 K is filled at the bottom with 12.1 cm of Hg, and 5.6 cm of wa

Radda [10]

Answer:

$1170839.28 dyn/cm^2$

16.9816 psia

$117.083928 kN/m^2$

Explanation:

To calculate the absolute pressure in the bottom of tube we need to sum the atmosferic and gauge pressure.

$P_{abs}=P_{atm}+P_G$

And the gauge pressure is given by the contributions of columns of water ( $P_{w}$ ) and mercury( $P_{Hg}$ ), we can calculate the contribution of each column as:

$P= \rho g h$ (*)

where $\rho$ is the respective density, g gravity and h is height.

So we have all the data required to use the above equations ( $P_{atm}$ , height and density of each column) we only need to be carefully with the units.

For simplicity we can to express all pressure contributions in mmHg ( $P_{atm}$ , $P_{w}$ and $P_{Hg}$ ). Note that the units "x" mmHg means the pressure at the bottom of a column of mercury of "x" mm high. For example, in this case we have a column 12.1 cm of Hg, that is a column of 121 mmHg (passing from cm to mm only requires multiply by 10) pressure exerted by that column is 121 mmHg.

Now pressure of 5.6 cm (56 mm) of water would be 56 mm of water, but it is not the same that mmHg, since the density of water is lower, the pressure exerted by 1 mm of water is lower than the exerted by 1 mm of Hg. The conversion between mmHg and mm of water is given by the relation between the densities.

$mmHg=\frac{\rho_w*mmH_2O}{\rho_{Hg}}$

$mmHg=\frac{0.998*mmH_2O}{13.55}=0.0737 mmH_2O$

And pressure of water in mmHg is

$0.0737*56=4.1246 mmHg$

The absolute pressure is:

$P_{abs}=P_{atm}+P_G= 756 + 121 + 4.1246 = 881.1246 mmHg = 88.11246cmHg$

To pass to dyn/cm^2 units we need to use the equation (*)

$P= \rho g h = 13.55 \frac{g}{cm^3} * 980.665 \frac{cm}{s^2} * 88.11246 cmHg = 1170839.28 \frac{g}{cm s^2} = 1170839.28 \frac{dyn}{cm^2}$

Note: We need to use cm Hg for units coherence

Now passing from dyn/ $cm^2$ to kN/ $m^2$ (or kPa) we need to consider that 1 dyn is $10^{-8}$ kN and 1 $cm^2$ is $10^{-4} m^2$ .

$1170839.28 \frac{dyn}{cm^2} * \frac{10^{-8}kN}{1 dyn}*\frac{cm^2}{10^{-4}m^2}=117.083928kN/m^2$

Now passing kN/ $m^2$ to psia. We need to consider that 1 psia is 6.89476.

$117.083928kN/m^2*\frac{1psia}{6.89476kN/m^2}=16.9816 psia$

The focus of what a person or organization ought to do in when faced with a particular situation is referred to as: a. Substanti

galben [10]

Answer:

c. Normative ethics

Explanation:

Ethics involves the study of the moral principles and guidelines that determines how an individual behaves. Since people and organizations operate in a social environment, where they interact with other organizations and people, ethics has to be considered to improve how people and organizations act and behave.

1. Substantive ethics

Substantive ethics involves the formulation of guiding principles that can be used during cases of ethical dilemma.

2. Emotional ethics

It consists of the feeling and intuition that play a major role into how people behave in a given situation.

3. Normative ethics

It involves the study of ethics by looking at how an individual ought to act and the implications of that behavior. It involves asking questions about how one needs to behave in a given situation then considering the ethics of that action. It is a kind of predetermined cause of action that an individual is supposed to apply in order to arrive at specific ethical behavior.

4. Behavioral ethics

Behavioral ethics involves the study of ethical and unethical behavior and coming up with reasons as to why individuals choose to behave ethically or unethically.

Ronald, Ross, and Carol opened a partnership firm. Ronald has a capital of $77,000; Ross has a capital of $119,000; and Carol

gtnhenbr [62]

Answer:

A. Carol, Capital is debited for $4,500

Explanation:

The question says to determine amount to be included in the journal entry to record Ronald's withdrawal from the partnership

Assumption: Equal Profit- loss sharing is the agreement between the existing partners.

First premise: Ronald's Capital in the Partnership = $77,000

However, Ronald received a payment of $86,000 meaning that there is an excess of $86,000-$77,000= $9,000

Since the agreement is equal profit and loss sharing, it means each of Ross and Carol will contribute 1/2 of the $9,000.

The journal entry to record this transaction is as follows:

Particulars Debit Credit

Carol Capital Account $4,500

Ross Capital Account $4,500

Ronald Capital Account $9,000

Being the equal contribution of excess amount paid to Ronald on exit from the partnership by Carol and Ross.

Based on the multiple choices, the correct answer is Carol, Capital is debited for $4,500

A personal trainer is advising a client on caloric distribution. Which of the following falls within the Acceptable Macronutrien

Aleonysh [2.5K]

Answer: C. 0.3

Explanation: The Acceptable Macronutrient Distribution Range (AMDR) usually expressed as percentage of total daily intake of energy is defined as the range of intakes for a particular energy source (protein, fat, carbohydrate etc) that is associated with reduced risk of chronic disease while providing adequate intakes of essential nutrients required by the body. For proteins this is within the range of 10 to 35%, expressed as fraction, 0.1 to 0.35. Option C falls within this range and therefore is the correct answer.

Costs, also called differential costs, are the additional costs from selecting a certain course of action.

Ilia_Sergeevich [38]

It is true that Costs, also called differential costs, are the additional costs from selecting a certain course of action.

<h3>What is differential costs?</h3>

Differential cost serves as the difference between the cost of alternative decisions.

Therefore, It is true that Costs, also called differential costs, are the additional costs from selecting a certain course of action and the cost do take place when a business have several similar options,
