The following quesiton pertains to a strain gauge on a cantilever beam often used in labs.

Are there any advantages in placing a strain gauge at one point on the beam as opposed to another? In general, what should the criteria be for choosing locations for strain gauges? Consider where on the beam the strain will be of highest amplitude or of highest frequency. What do you want (i.e. what criteria is most important)?

In order to get the most accurate readings, should a strain gauge have a high stiffness or a low stiffness? Explain.

I make threesaturated solutions of AgCl (Ksp= 1.8•10-10). The first is in pure water, the second is in 0.01 M KNO3, and the third is in 0.01 M NaCl. I measure the concentration of Ag+in each solution. Which has the highest Ag+concentration? Which has the lowestAg+ concentration? Please explain why there are differences in concentrations between the solution with the highest and lowest concentrations. I’m not asking for the actual concentration, so you don’t need to do any math.highest: _________________________________lowest: _________________________________why:

1. a) A neutral atom has the following characteristics:

- it has 8 valence electrons

- it's a transition metal

- the highest quantum level occupied is n = 4

What is the identity of this atom? Enter either the element name or symbol

1. b)

A neutral atom has the following characteristics:

- it has 5 valence electrons

- it's a main group element

- the highest quantum level occupied is n = 4

What is the identity of this atom? Enter either the element name or symbol (case insensitive).

Gathering and graphing data

Go to the Federal Reserve Bank of St. Louis FRED database and obtain annual data from

1970 to 2016 on “Constant GDP per Capita” for each of the G7 countries (Canada,

France, Germany, Italy, Japan, the United Kingdom, and the United States).

a. Move each country’s data on the same Excel spreadsheet and plot the series.

Which country had the highest GDP per capita in 1970? Which country had

the highest GDP per capita in 2016?

Our perception of accounting, as noted in our conversation of Accounting Professionalism and tracing its written origin to Luca Pacioli, is of the highest standard. Accounting is a tool to produce financial records of the highest integrity of absolute trust. As one reads through the early history of accounting (circa the 1400s and 1500s), however, it appears that accounting was viewed in a very negative light. Why was this the case? Do the same associations that caused accounting to be considered negatively in the 1400s and 1500s remain today? If so, how, and if not, why not?

Write a program that uses the defined structure and all the above functions. Suppose that the class has 20 students. Use an array of 20 components of type studentType. Other than declaring the variables and opening the input and output files, the function main should only be a collection of function calls. The program should output each student’s name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score.

Theory of computation:

Consider the alphanumeric alphabet Σ = {a, b, . . . , z, A, B, . . . , Z, 0, 1, . . . , 9} and let L be the language of all regular expressions over Σ:

L = {w ∈ Σ ∪ {∅,(,), ∪, ·, * }* | w is a syntactically legal regular expression over Σ}

Give an unambiguous context-free grammar that generates L. The grammar should use the following precedence levels, from highest to lowest:

(1) * (Kleene star) – highest precedence

(2) · (concatenation)

(3) ∪ (union) – lowest precedence

Using C# Design and implement a program (name it ProcessGrades) that reads from the user four integer values between 0 and 100, representing grades. The program then, on separate lines, prints out the entered grades followed by the highest grade, lowest grade, and averages of all four grades. Format the outputs following the sample runs below.

Sample run 1:

You entered:   95, 80, 100, 70

Highest grade:100

Lowest grade:  70

Average grade:86.25
