Name at least two sources of systematic error and explicitly describe how you could improve the experiment to obtain a better measurement of Y in Young's Modulus lab.

PhD candidates should provide an authentic personal statements to each of the five following questions/prompts reflecting on their own personal interest. In the event that any outside resources are used, resources should be cited in APA format. Submissions should be a maximum of 500 words or 125 words per question/prompt. It is best to respond to each prompt/question individually for clarity of the reviewer. Documents should be submitted in Microsoft Word format.

Part 1 Write a program that displays a frame containing two labels that display your name, one for your first name and one for your last. Experiment with the size of the window to see the labels change their orientation to each other. USE FIRST NAME: Aya LAST NAME: KAYED. SEND THE CODE IN THE EXACT FORMAT FOR JAVA ECLIPSE. I WILL COPY AND PASTE THE CODE SO I CAN RUN IT. Part 2 Propose and solve your own digital design problem.

Compute the thermal utilization factor for a nuclear reactor core where there are 50 moles of heavy water per mole of 5% enriched uranium monocarbide (UC). What would be the value if light water replaced heavy water?

Determining the Speed of Sound Name Abstract; Include instead of these lines the objectives of the lab (what you investigated), the short description of how you did it and the conclusions formulated based on the obtained results. It should be ½ to 1 page long. Picture of the experimental set up Observations Data Table 1: Calculation of sound wavelength Tuning fork frequency f (Hz ) Length, (water level to top of tube) L (m) Diameter of tube, d(m) λ(m) =4(L + 0.3d) Experimental v(m/s) = f λ Room Temperature, oC Calculations A. Calculate the theoretical speed of sound (v): v = 331.4 + 0.6T0C ( m/s) • 331.4 m/s is the speed of sound at 20oC • T0C is the temperature of air during testing measured in Celsius B. Calculate the percent error of your experimentally derived value: C. Describe what is sound. D. Explain the phenomenon based on which you were able to hear the amplified sound and to determine the speed of sound. You should include a picture or a sketch of the standing waves (the key concept you need to write about) inside the tube. Because this might require different printed or electronic resources, make sure you include the references. E. What is the physical concept behind the “pitch” of a sound and what is the SI unit for it? F. What is the physical concept behind “intensity” of a sound and what is the SI unit for it? G. What are possible sources of errors in this experiment?

Perriot's Restaurant purchased kitchen equipment on January 1, 2014. The value of the kitchen equipment decreases by 15% every year. On January 1, 2016, the value was $14,450.

a) Find an exponential model for the value, V, of the equipment, in dollars, t years after January 1, 2016.

b) What is the rate of change in the value of the equipment on January 1, 2016?

c) What was the original value of the equipment on January 1, 2014?

d) How many years after January 1, 2014 will the value of the equipment have decreased by half?

What are strengths and weaknesses of each of the major types of epidemiologic study?

-Randomized controlled trial

Question 1

Download the files Book.java and BookInfo.txt from Content->Chapter 12 Quiz Files. Create a BookDriver.java class with a main method. In the main method, create an ArrayList of Book objects, read in the information from BookInfo.txt and create Book objects to populate the ArrayList. After all data from the file is read in and the Book objects added to the ArrayList- print the contents of the ArrayList. Paste your BookDriver.java text (CtrlC to copy, CtrlV to paste) into the open space before. You should not change Book.java or BookInfo.txt.  

Given info below :

In a famous prospective cohort investigation, the population to be studied encompassed all physicians listed in the British Medical Register and resident in England and Wales as of October 1951. Information about present and past smoking habits was obtained by questionnaire. Information about lung cancer came from death certificates and other mortality data recorded during ensuing years.

1. What makes this study prospective? List two advantages and two disadvantages of this approach.
2. What advantages and disadvantages come with selecting physicians as a cohort for follow-up?

. Create a class called Book to represent a book. A Book should include four pieces of information as instance variables‐a book name, an ISBN number, an author name and a publisher. Your class should have a constructor that initializes the four instance variables. Provide a mutator method and accessor method (query method) for each instance variable. Inaddition, provide a method named getBookInfo that returns the description of the book as a String (the description should include all the information about the book). You should use this keyword in member methods and constructor. Write a test application named BookTest to create an array of object for 30 elements for class Book to demonstrate the class Book's capabilities.
