A device has two states: ON and OFF. When it works normally, it spends a random time in the ON state, then a random time in the OFF state, then again in the ON state, and so on. However, when switched from OFF to ON, the device fails with probability 0.05 and a replacement process is triggered immediately. Once a new device is in place, it is turned ON. Suppose that the average durations in the ON and OFF states are 40 and 20 minutes, respectively, and that it takes 20 minutes to replace a failed device.

(a) In the long run what is the rate at which devices are replaced?

(b) In the long run what is the fraction of time that the device is ON?

Kirchoff stated 2 laws concerning currents in an electrical circuit.
[1] One of these states that the sum of the potential changes (voltages) around any closed loop equals zero. What property of the electric potential at a point is the basis for this law?

[2] The other law states that the sum of currents entering a node must equal the sum of the currents leaving the node (or the sum of currents, with signs, at a node equals zero). (a) Given perfect conductors, what is the net charge at a node?

(b)What conservation law, when combined with (a), forms the basis for this second Kirchoff law?

1. State Sales Tax is a complex area due to the enormous volume of taxing jurisdictions, each with different definitions, tax rates and exemptions. Would it make more practical sense to have a Federal Sales Tax (with all associated revenues allocated to the States) and eliminate the complexity at the state level? Do you think States would be in favor of a Federal Sales Tax to replace State and Local Sales taxes?

2. In the aftermath of the Wayfair decision, some taxpayers are concerned that Physical Presence may no longer be required for Income Tax Nexus. Is this concern justified?

50 mL of 2.0 M NaOH is added to a 1.0L buffer solution that is 0.20M in HF and 0.20M in KF. The ka for HF is 3.5 x 10^-4.

1. Write the reaction or the buffer only including states and excluding spectator ions.

2. Write the neutralization reaction that occurs after the addition of LiOH including states and excluding spectator ions.

3. Calculate the amount of moles remaining and the final concentration for each component of the solution after the neutralization reaction occurs.

4. Calculate the resulting pH of the buffer - be sure the include validation if approximation is used.

Boltzmann Statistics

A molecule has three degenerate excited vibrational states, each with excitation energy above the ground state

a) At temperature T, what is the ratio between the number of molecules in (all of) these excited vibrational states and the number in the ground state?

b) At very high T, what is this ratio?

c) Assume you have N distinguishable molecules of this type. Use the free energy to compute the

entropy S/k of the system at temperature T.

d) Compute the number of microstates in the equilibrium macrostate at high temperatures and

explain why your answer makes sense.

Write a brief reaction to the sentence below. (150-300 words)

Apparently, cutting off their military supplies will be the most effective way to prevent terrorism. Their military weapons are mostly sold by other states, who want to make profits and gain other sort of political interests. Terrorism can only produce a little amount or even zero amount of weapons. However, there are other states that is secretly selling weapons to the terrorists. We should cut off their military supplies, and then help them to build their own government to solve root causes.

Case Scenario: A 75-year-old woman is in for her yearly exam. She states that sleep is challenging as she has pain in her upper back. She has been in good health other than the pain from her back. She has led an active life as a tennis player and states her activities are diminished by the pain. The doctor diagnoses osteoarthritis.

Question: Explain risk factors for osteoarthritis, detailing who might be at most risk for the disease. Support your answer using specific facts, data, examples, and other information

1. A sequence detector is monitoring a serial input stream looking for either 0101 or 0110. The output is two consecutive cycles of 1’s, with the first of the two being asserted in the same cycle as the last input matching the sequence; in other words, it has to be a Mealy machine.

   1. Draw the state diagram for this sequence detector

   2. Assign states and create the state table, showing next states and output as a function of current state and input. You can call your state, input, and output variables

      anything you want.

   3. Write a Verilog module that implements the behavior
