3. In ion mobility spectrometer, the ions are accelerated under a constant electric field in a cylindrical tube and the time of flight of the ions in this tube is measured. The ions are detected by using a sensor at the end of the tube. a) What type of sensor can be used to detect the ions? b) The experiment is performed at high frequencies to be able to decrease the effect of the noise. What type of noises can be present in this experiment?c) During the experiment, many devices are used together. What type of grounding can be used for this experimental setup to be able to prevent floating grounds and crosstalks? d)

The mobility of the ions is given as ? = ? ? 1 ? , where l, E and t are the length of the tube, the electric field strength and the time of flight, respectively. The data given in the table belongs to a specific type of spectrometer. By plotting this data, find the required length of the tube for an electric field strength of 10^4 V/cm.

Assume that the firework has a mass of m_0 = 0.30~\text{kg}m​0​​=0.30 kg and is launched from a cannon at an angle of \theta_0 = 41.8^\circθ​0​​=41.8​∘​​ with an initial velocity of | v_0 | = 20~\text{m/s}∣v​0​​∣=20 m/s. Just as the firework reaches its hight point in its trajectory, it explodes into two pieces. Immediately after the explosion, the first piece, with a mass of m_1 = 0.2~\text{kg}m​1​​=0.2 kg flies off at an angle \theta_1 = 150^\circθ​1​​=150​∘​​ relative to the positive (forward) horizontal axis at a velocity of | v_1 | = 5~\text{m/s}∣v​1​​∣=5 m/s relative to the ground. Calculate the trajectory angle, \theta_2θ​2​​ of the second piece immediately after the explosion. Assume the second piece has a mass of m_2 = 0.1~\text{kg}m​2​​=0.1 kg, neglect the effect of air resistance, and report your result as an angle relative to the positive (forward) horizontal axis.

There are two traffic lights on a commuter's route to and from work. Let X₁ be the number of lights at which the commuter must stop on his way to work, and X₂ be the number of lights at which he must stop when returning from work. Suppose that these two variables are independent, each with the pmf given in the accompanying table (so X₁, X₂ is a random sample of size n = 2).

Adrian is a salesperson who represents several wholesale companies. On January 2, 2018, she receives by mail a commission check from Ace Distributors in the amount of $10,000 and dated December 30, 2017. Adrian is concerned about the year in which the $10,000 is taxable. Although the check is dated 2017, she contends that it would have been unreasonable for her to drive the 50 miles to the Ace offices on a holiday to collect the check. Further, Adrian maintains that even if she had made the trip to collect the check, by the time she returned home, her bank would have closed and she could not have received credit for the check until after the first of the year. Adrian would like you to determine whether she should include the $10,000 on her 2017 or 2018 tax return. §61; Reg. §1.451-1; Murphy v. U.S., 71 AFTR 2d 93-1862 (CA9, 1993); Kahler, 18 T.C. 31 (1942); Zahirdueen Premji, et ux. v. Commissioner, TC Memo 1996-304.

ETHICS

Why Be Moral?

Plato tells the story of Gyges (The Republic, Book II), a shepherd, who finds a magic ring. When Gyges turns the ring 180˚, he becomes invisible, and upon turning the ring again, he reappears. Under the cloak of invisibility he performs a series of unethical and immoral acts, including murder. He is a villain and rogue yet becomes wealthy and famous. Gyges not only accrues benefits by appearing to be moral but also enjoys the bounty reaped from wrongdoing with no punishing consequences – he will never be caught!

Now imagine a second magic ring given to a just and upright individual. Will the temptation to engage in wrong-doing for personal gain be too great? Knowing there will be no punishing consequences, would a good person quickly turn into a scoundrel? Given the situation just described, why the need to be moral?

What would you do if you were given a Gyges ring?

Discuss your answer in 100-150 words minimum.

Title VII of the Civil Rights Act prohibits employment discrimination on the basis of sex, race, color, national origin and religion. There are two cases currently pending before the U.S. Supreme Court asking the court to interpret the meaning of "sex" in the context of employment discrimination. In R.G. & G.R. Harris Funeral Homes Inc. v. Equal Employment Opportunity Commission (Links to an external site.), the Court is asked to decide if discrimination based on a person's transgender status is addressed in the Act as discrimination based on "sex" as the law is intended to operate. Meanwhile, in Bostock v. Clayton County, Georgia (Links to an external site.), the Court is asked to decide whether sexual orientation is included under "sex" according to Title VII. In two or three paragraphs (minimum four sentences each), please give your opinion on the following: 1. Whether Congress could have intended the term "sex" to include sexual orientation and/or transgender status when the law was written; and 2. Whether the courts should now interpret the term "sex" to include sexual orientation and/or transgender status.
