Consider a gas of diatomic molecules at temperature T, each with moment of inertia I. If Eg is the ground-state energy and Eex is the energy of an excited state, then the Maxwell-Boltzmann distribution predicts that the ratio of the number of molecules in the two states is nex ng = e −(Eex−Eg)/kBT . (1) a) Suppose we consider the excited state to be the ℓth rotational energy level, and the ground state to be ℓ = 0. Show that the ratio in equation (1) is equal to nℓ n0 = (2ℓ + 1)e −[ℓ(ℓ+1)¯h 2 ]/(2IkBT) . (Hint: the ℓth level contains multiple different states with different values of mℓ, all with the same energy. How many different values of mℓ are there for a given value of ℓ?) b) The moment of inertia of the carbon monoxide (CO) molecule is 1.449×10−46 kg·m2 . Use this to determine the numerical value of the ratio nℓ/n0 for a gas of CO molecules at a temperature of 300 K, for the following cases: (i) ℓ = 1 (ii) ℓ = 2 (iii) ℓ = 10 (iv) ℓ = 20 (v) ℓ = 50 c) Comment on your results from part (b). What do you see happening to the ratio as ℓ increases? Why does this happen? What does it tell us about the physical system?

You are assigned the task of determining the bacterial density of newly-grown culture. You decide that you will analyze the sample with two methods, spectrophotometry and dilution plating. Your results show the sample tested using spectrophotometry had a bacteria density that was roughly ten folds that of the plated sample. Please explain in detail.

Question 2 (300-500 words)
Every society, regardless of its wealth and power, must make certain choices
about production and distribution. Specifically, every society faces three basic
economic decisions:
What goods and services to produce and in what quantities?
How to produce these goods and services, or how to use the economy's
resources?
Who gets these goods and services
Briefly explain how these questions are answered in your country. How does the
availability of resources in your country influence the economic decisions fo individuals,
organizations, and government?

Please respond to all the questions below:

1. (a) What is the current U.S. federal debt? (To find this, you can go to US Gov't Dept of Treasury website.) (b) What is the current U.S. federal federal budget deficit?  (Search the internet to find the deficit for last year or an estimate of the deficit for this year. Cite your source.) Explain why our current federal debt is so much larger than our current federal deficit.

2. How would a government deficit likely affect (a) interest rates and investment?

3.  Most state governments are required to balance their budgets. Do you think our federal government should be required to always balance its budget? Briefly explain why or why not. Remember to use economic reasoning!

  1. Clinical assistants in the dental office have various levels of education and credentials. The dentist uses them all to perform the same types of tasks. The credentialed assistants have asked the doctor not to assign specific tasks to the non-credentialed assistants as this is a violation of the state dental practice act. As the administrative assistant, the clinical assistants have asked you to clarify this assignment.

  1. How do you locate the state dental practice act?

  1. What should the dentist do to rectify this situation once the duties are clarified?  
  1. What are some tips for successful records Management?
  1. Explain the use of email in the dental office and the importance of applying common business etiquette to the use of email.
  1. What are the characteristics of effective correspondence?

5.. What are the various types of written communication in a dental office?

I am supposed to answer these conceptual questions with this lab simulator, but I can never get the simulator to work https://phet.colorado.edu/en/simulation/legacy/energy-skate-park

Help please?

Energy State Park Lab Handout

Click on the “Energy State Park Simulation” link to perform simulations in the setup satisfying the given conditions.

Upon opening the simulation, the skate should be alternating between the walls of the skate park with no friction added and with Earth’s gravity. Click on the Show Pie Chart under the Energy Graphs section.

  1. With no friction, will his motion every stop?

  1. What principle can be applied to this situation?

  1. What type of forces are applied here? (Conservative/Non-conservative)

  1. What happens to the skater’s potential energy has he falls down a wall to the valley? What about when he moves up a wall from the valley?

  1. What happens to the skater’s kinetic energy has he falls down a wall to the valley? What about when he moves up a wall from the valley?

  1. Will any kinetic energy be transformed into thermal energy? If so , why? If not, why?

  1. Where does the skater have the maximum potential energy?

  1. Where does the skater have the maximum kinetic energy?

Now change the coefficient of friction to half way between None and Lots.

  1. Are there any non-conservative forces in this simulation? If so what force?

  1. With friction, will the skater ever stop?

  1. Would thermal energy be created with this situation?

Conceptual Questions:

  1. What is the formula for kinetic energy?

  1. What is the formula for gravitational potential energy?

  1. If the 75 kg skater reaches a maximum height of 5 feet, what is his maximum gravitational potential energy? (Hint: remember to convert to meters).

  1. Is gravitational potential energy a conservative or non-conservative force? Is friction force a conservative or non-conservation force?
