Description

Consider a point source of light. How would the intensity of light vary with distance from the source according to the (a) wave theory, (b) particle (photon) theory? How can these two theories mesh?

Explanation & Answer

According to wave theory, the light waves will move in all directions from the point source. And according to the particle theory, it will move in the straight line from the point source.

PGU Criminology Juvenile Justice System versus Adult Justice System Discussion

The Juvenile Justice System and the Adult Justice System both have similarities and differences in the overall handling of offenders. In your learning activity, you identified those processes that are the same for both juveniles and adults or those processes that are different for both juveniles and adults. In this written assignment, you will:Select four (4) of the processes identified in the Learning Activity and clearly compare and contrast their treatments in the juvenile and adult courts. (At least one full paragraph per comparison). 1. self incrimination 2. appeals 3. diversion programs 4. plea bargainDo you feel there are enough significant differences between the two systems to justify having a separate juvenile system? Justify your rationale. Yes there is enough evidence is my positionthere is no page or word limit it just needs to have 4 paragraphs plus intro ans conclusion

OCC Societys Role in Reducing Antibiotic Resistant Microbial Strains Discussion

Antibiotics have saved millions of lives since they were first observed by Pasteur and Koch and later named by Selman Waksman in 1942. Unfortunately, antibiotic-resistant microbial strains are becoming more prevalent and therefore making once easily treated infections more difficult to treat.For your initial discussion post, share your thoughts on three ways that society—not physicians or medical staff—can help to reduce the development of drug-resistant microbial strains.

CHEM Miami Dade College Process of Acid Base Titration Presentation

The goal of your Signature Assignment is to show that you can compute properties of solutions and analyze and interpret data. You will create a PowerPoint presentation that shows the process of going through an acid/base titration like you would if you were in a physical lab.For the presentation:You will prepare a sample of an unknown acid to titrate using a known concentration of base. You will set-up a burette filled with a known concentration of base and use proper titration techniques to reach an end-point to the titration. You will then calculate the concentration of the unknown acid on your own.For Part I: Create a PowerPoint presentation (4-6 slides) that covers the lab scenario above. Include your thoughts on why understanding acid/base titration is important to your future career, and how you will use this concept as you complete your degree. Your presentation must consist of more than merely a series of bullet points to earn full credit. Use the Notes section for each slide to fully explain your answers. For Part II: Your instructor will provide guidance and examples for completing calculations for titration. This assignment should be in current APA Style with both a title slide and a reference list that includes all of the sources used. At least two scholarly sources should be used (your textbook can be one of the sources).See rubric for specific grading criteria.Points: 100Due: Sunday, 11:59 p.m. (Pacific time)
