A Explain briefly why actual unemployment is never zero even when the economy is considered to be in a state of full employment. B why do economists and business investors expect inflation to accelerate when actual unemployment falls below the natural rate of unemployment (NAIRU)? C What is the current actual unemployment rate for the US economy? Do you think the current unemployment rate is less than, equal to or above NAIRU?Explain your answer.

(a) Let n be any positive integer. Briefly explain (no formal proofs) why n > 1 ≡ ¬(n = 1). (b) Recall that a positive integer p is prime iff there do not exist a positive integers n and m, both greater than 1, such that p = nm. (I.e., Prime(p) means ¬∃n ∃m (n > 1 ∧ m > 1 ∧ p = nm).) Give a formal proof of the following: for any prime p, any positive integers n...

Briefly explain how the micrometer works (i.e. what one full rotation of the rod means, the relationship between “horizontal” and “vertical” increments on the micrometer, and how the distances are converted to a voltage measurement.) What is the relationship between voltage and displacement, as examined in the LVDT experiment? Were the voltage readings within the linear range of the LVDT? After taking a few readings, was the voltage reading still zero when you returned to 0.500 inches on the micrometer?...

Please explain why you chose the answer as I do not understand the question. When a mixture of glucose 6-phosphate and fructose 6-phosphate is incubated with the enzyme phosphohexose isomerase (which catalyzes the interconversion of these two compounds) until equilibrium is reached,the final mixture contains twice as much glucose 6-phosphate as fructose 6-phosphate. Which one of the following statements is best applied to this reaction outlined below? glucose 6-phosphate<-->fructose 6-phosphate a. delta G is incalculably large and negative b. delta...

4- Explain what is meant by TSR....and fill in the table. Tip-Speed Ratio 2 is the ratio of the speed of the rotating blade tip to the speed of the wind. If the TSR 2. is above 1, that means there is lift involved to make the blades spin faster than the wind speed. If the TSR is below 1, there is a lot of drag going on! Wind speed (Higher/Lower) Tip Speed(Higher/Lower) TSR More than 1 Equal to 1...
