y (x , t)= A sin (k x − ω t )
calculate the vertical position y in [cm], vertical speed vy in [m/s] and vertical acceleration ay in [m/s2] of the wave that the wave driver generated at x = 15 cm and at time t = 3 s during trial 5 of this experiment. Assume that A = 2 cm. The other values in the equation can be calculated from the experimental data. Remember to differentiate the above equation to get the expressions for vy and ay. Answers: y = 1.5 cm, v = - 3.9 m/s, a = -1500 m/s2

3. a) Draw a schematic diagram of an X-ray diffractometer. [4 marks]

b) The results of an X-ray diffraction experiment that used X-rays of wavelength 0.154 nm show the first 6 peaks at angles of 40.6°, 58.8°, 73.8°, 87.8°, 101.8°, and 116.4°.

i) Use this information to determine the possible crystal structures of the sample. [10 marks]

ii) An additional scan was performed on the sample and an additional peak was observed at an angle of 133.2°. Determine the crystal structure of the sample. [3 marks]

iii) Calculate the Miller indices for each of the measured peaks. [7 marks]

iv) Draw the orientation of the crystal plane within the unit cell corresponding to the peak at 101.8°. [3 marks]

v) Calculate the lattice constant and identify the sample. [3 marks]

1/ Can Foothill College (a publicly funded community college) discriminate in the hiring of its instructors based upon religion? Can Santa Clara University (a private, Catholic-affiliated university in Santa Clara, CA) do so? More generally, if an employer is sued for discrimination, what defenses against an allegation of discrimination does the employer have? ( the discussion about bona fide occupational qualifications)

2/ How might employers be proactive in avoiding employment discrimination claims? For instance, when Silicon Valley law firms lay off attorneys, they typically provide a cash severance payment, which is payable if and only if the laid-off employee waives any and all claims with respect to employment discrimination. Is this a good idea for the employer? Why or why not.

3/ A friend of the instructor’s was laid off several years ago by a small Silicon Valley consulting firm and, as part of the lay off paperwork, he was asked to sign an employment discrimination waiver in exchange for receipt of his final paycheck, but no additional severance payment was offered to the laid-off employee by the employer. On these facts, can you see a reason for why the waiver might be deemed invalid if the ex-employee decided to then sue the employer for employment discrimination?

Explain what the author of International Trade: The Basics present as the 'second golden age of trade'. When and why did it happened and what is GATT that was created during this period.

Daniel Kahneman, co-author of Thinking, Fast and Slow, asserts that cognitive biases often lead to errors in judgment. How can such errors impact stress and coping?

Develop a program Grades.java that collects the user's (students) name, course name, and the score for three quizzes. You are supposed to read this data from the keyboard using the Scanner class. Calculate the total score and the average score.

Further, using the grading scale below, based on the average score computed above, your program should calculate and output a letter grade. and the range boundaries should be configured properly (i.e.: exactly 90 and above is an A, and anything less than 90 to exactly 80 is a B). The grading scale to use is as follows:

Note: The E Category is not a typo.

Declare the variables in the order studName, courseName, scoreQuiz_1, scoreQuiz_2, and scoreQuiz_3, totalScore, averageScore, and letterCategory. Make sure you declare the variables studName, courseName, and letterEvaluation as String class variables. Select proper data type for the variables totalScore and averageScore. The data type should support decimals. Use a constant variable NUM_OF_Quizzes to compute the average score.

Things to watch for: As you are determining your logic for your if statements in this project, consider that a percentage of 90.0 results in an A, 89.8 results in a B category, 79.12 results in a C category, and 69.994949 results in a D category. That last example is a bit extreme, but the idea is to not try to predict how many 9s after the decimal you need to account for. Just think of where the last boundary ends and where the next one begins, and how you might use your mathematical operators to account for that (is it less-than-or-equal-to, or just less than?).

Formatting: Import the package DecimalFormat to format the average score data. You do this by typing: import java.text.DecimalFormat; either below or above the line: import java.util.Scanner;

Then create a DecimalFormat object by typing: DecimalFormat df = new DecimalFormat("##.00"); either above or below the line Scanner scnr = new Scanner(System.in);

A format with 2 digits would be displayed by using the df as follows:

System.out.println("The average score is: "+df.format(averageScore));

Pseudocode: Prior to writing the Java code for the project, develop a document in pseudocode that outlines how the program will flow. Remember that there are no specific rules regarding pseudocode, but rather you should write pseudocode in a way that is human-readable and understandable (English for this assignment).

The following example is what your program might look like:
