The production of sound during speech or singing is a complicated process. Let's concentrate on the mouth. A typical depth for the human mouth is about 7.4 cm , although this number can vary. (Check it against your own mouth.). We can model the mouth as an organ pipe that is open at the back of the throat.

a) What are the wavelengths of the first four harmonics you can produce if your mouth is open?

Express your answers in centimeters separated by commas.

b) What are the frequencies of the first four harmonics you can produce if your mouth is open? Use 351 m/sm/s for the speed of sound.

Express your answer in hertz separated by commas.

c) What are the wavelengths of the first four harmonics you can produce if your mouth is closed?

Express your answers in centimeters separated by commas.

d) What are the frequencies of the first four harmonics you can produce if your mouth is closed? Use 351 m/sm/s for the speed of sound.

Express your answer in hertz separated by commas.

Summary of the United States and China

Summary must be at least 250-words or more in length

Conclusion to summarize your findings, and

Reference page (Reference page must be at the end of your paper and on a separate page).

A.Prepare general journal entries to record the March 16 sale using the

1. FIFO inventory valuation method.
2. LIFO inventory valuation method.

Glucose (C6H12O6) is the primary source of metabolic energy for vertebrates.

a)Determine the amount of available glucose in 500g of sucrose

b)Write a balanced chemical reaction for the combustion of glucose. The products of the combustion are carbon dioxide and liquid water.

c)Using tabulated Gfo values, calculate the free energy of reaction for the combustion of glucose.

d)A normal human body requires approximately 2000 kJ of energy to sustain itself. Assuming that glucose is the primary source of metabolic energy, how many grams of glucose must be consumed in order to provide 2000 kJ of energy?

e)The metabolism of glucose in vertebrate systems requires a number of steps, which when added together result in the reaction from part (a). Explain why it is possible to calculate the metabolic energy even though there is more than one step in the process.

Write reactions that correspond to the following changes.

a)Gof for solid Aluminum oxide

b) the standard free energy of combustion of liquid ethanol, C2H5OH(l).

c)the standard enthalpy of neutralization of barium hydroxide solution by aqueous hydrochloric acid.

d) aqueous HCl

] Accreting, spinning, magnetized systems tend to:

1. Accelerate
2. Grow in mass
3. Produce jets
4. Produce supernovae
5. Cannot be predicted

[28] If space had been found to be negatively curved, the other evidence might have us conclude that:

1. The universe will re-collapse
2. The need for dark energy is even greater
3. There might be little or no dark energy
4. Omega =1 exactly
5. None of the above

[29] The “anthropic principle” addresses the idea that:

1. The universe seems conducive to life
2. The universe is homogeneous everywhere
3. The universe can be explained via rational explanations
4. The study of cosmology is common to all human cultures
5. None of the above

30. The “principle of equivalence” states that:
    1. Masses of fundamental particles are the same everywhere
    2. All universes in a multiverse are similar  
    3. Acceleration in a gravitational field in similar to the acceleration by a rocket D) Mass and energy are equivalent (E = mc²)

31. Type Ia supernovae are:
    1. Exploding neutron stars
    2. Exploding hydrogen rich white dwarf stars
    3. Exploding helium / carbon white dwarf stars
    4. Exploding massive stars stripped of their hydrogen envelopes
    5. Exploding hydrogen-rich massive stars

For data to be actionable and valuable to business professionals, it has to be clearly and effectively communicated to the right stakeholders. Sharing data with the relevant people is often done via a verbal presentation, using data visualisations as an aid. There are a number of factors to consider when you are planning a presentation of your findings to a specific audience - you should determine the exact topic to report on, as well as the way you should report it. Consider, for example, how data presentation may differ if you are reporting to finance executives as opposed to human resource managers.

Discuss what factors you think need to be considered when it comes to presenting data to different target audiences or stakeholders. Consider the following questions to help guide your response:

• To whom must you report which statistics?

• What amount of detail is necessary for you to communicate the findings
• Are there any industry-specific considerations?
• Are there any business-role-specific considerations?  

Share your thoughts and insights with your peers on the class-wide forum, and include in your discussion any personal insights you have gained from your professional experience.

a. Does not support personal experience

b. Results in an intended outcome

d. All of the above
