28 Marks Total ASSIGNMENT 14 Compton, de Broglie, and Wave-Particle Duality (1) There are similarities and differences between the Photoelectric Effect and Compton Scattering. Complete each of the six partial statements below using the following guide; all you need to provide for an answer is PE, CS, BOTH, or NEITHER. • PE if the statement only applies to the Photoelectric Effect • CS if the statement only applies to Compton Scattering • BOTH if the statement only applies to both the Photoelectric Effect and Compton Scattering • NEITHER if the statement applies to Neither the Photoelectric Effect or Compton Scattering a. Energy is conserved in _____. Answer: (1) b. Photons are observed before and after the interaction in _____. Answer: (1) c. Electrons are observed as the result of the experiment in _____. Answer: (1) d. Angles are measured in the experiment in _____. Answer: (1) e. Photons with very low energies such as 5.0 to 10.0 eV is observed in _____. Answer: (1) f. Ionization occurs in _____. Answer: (2) 2. What quantity measured in the Compton effect experiment show the wave-particle duality of light? Answer: (5) 3. An X-ray with a frequency of 3.74 × 1020 Hz is incident on a thin piece of metal. The lower frequency X-ray on the other side is observed deflected at 48o. What is the frequency of the deflected X-ray? Answer: (5) 4. A scientist changes the frequency of an incident X-ray to 4.50 × 1019 Hz and measures the deflected X-ray frequency of 4.32 × 1019 Hz. What was the angle of deflection? Answer: (2) 5. Can the equation E = pc be applied to particles? Why or why not? Answer: (3) 6. A stationary hydrogen atom with a mass of 1.67 × 10-27 kg absorbs a photon of light with 10.2 eV. What is the velocity of the hydrogen atom after absorbing the photon in a perfectly inelastic collision? Answer: (2) 7. Describe the results of performing Young’s experiment with x-rays and then high speed electrons. Answer: (2) 8. How do the results of performing Young’s experiment with x-rays and then high speed electrons support the wave-particle model? Answer: (1) 9.

You are an investigative reporter for a large news network. You are working on a news piece identifying how theories of crime explain specific crimes including the demographics of perpetrators and victims. You are required to make a thirty-minute presentation to your producers to convince them to run your story.

Choose a specific crime from the Uniform Crime Reporting (UCR) Program at the following:US Department of Justice, The Federal Bureau of Investigation. (2009). 2008 Crime in the United States: About crime in the U.S. Retrieved from 
http://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2008

Research this crime using your textbook, the Argosy University online library resources, and the Internet. Be sure to include the UCR and other crime reports in your research

Based on your research, develop a presentation that addresses the following:Define the crime. Include both the legal definition and others as necessary.Summarize demographics of the crime for both the perpetrators and the victim. Be sure to cover the following:GenderEthnicitySocioeconomic characteristicsOther relevant diversity issuesChoose two theories of the causes of crime that have been discussed and analyzed so far in the course; apply those theories to the selected crime. Be sure to cover the following:Explain the type of each theory in detail.Discuss the development of each theory and the main theorists associated with them.Compare and contrast the two theories of crime selected. Discuss the ways in which they fit with the crime and the specific demographics associated with the crime.Based on your research, develop your own hypothesis of the cause of this crime. Using the theories that you have chosen, you can develop your own “combination” theory.Give valid reasons and scholarly, peer-reviewed sources in support of your theory.

You are allowed to present your theory in first person; however, be careful not to abuse this privilege.

Your presentation should include the following:A title slide and a reference slide (these will not count towards the total number of slides).At least five sentences of speaker notes for each section to clarify anything not included in the slides. (As this is a presentation the slides should cover the main points and the details should be covered in the speaker’s notes.) The speaker notes should be properly referenced.

Develop a 10–15-slide presentation in PowerPoint format. Apply APA standards to citation of sources

target for potential killer 1

/in /by

The murder of a Manhattan graduate student in 2006 gained much attention not only for the brutality of the act but also for its location. The 24-year-old woman was chatting with her friend in a local bar till 2:30 A.M. After the friend left, the woman left for another bar half an hour later. Her friend could not contact her after that. Around 17 hours later, an unknown caller informed the police about a body lying near a road. The woman was found brutally murdered by suffocation. Evidence suggested that she might have also been raped and assaulted by the murderer.

What made the victim a suitable target for a potential killer? How could she have decreased her likelihood of victimization? In your opinion, could she have facilitated or precipitated her own murder? Provide a rationale for your answer. What could have she done to avoid landing in this situation? Cite at least two examples in which a “victim” overcame his or her victimizer.
