Explanation & Answer
F1 = 40 *sqrt(3) i -40 j
F2 = 60j
F3 = -40i
F = F1+F2+f3 = 40*0.732 i +20j
|F| = 35.46 N
it is D

Discussion post #5, biology homework help
https://owl.english.purdue.edu/owl/resource/560/10...Online discussion: Construct responses to only one of the following discussion questions. As always, keep your response scientific, and justify using information from scientific sources.Read the BIOLOGY MATTERS-Bioethical “DNA Fingerprinting and the Criminal Justice System”on page 497 of the text. As part of the criminal justice database, DNA samples are being taken and stored for further examination. What positive things could come from such a database? Should everyone, criminal or not, be asked to contribute to this database? How might the database be used to violate privacy? What kinds of information can be learned from a sample of your DNA? It is said that DNA evidence can exclude a person, but it can never prove a person guilty. What does this mean? Are there ever mistakes made in DNA fingerprinting? How reliable is it? (Refer to Chapter 21.)Discuss the value of new genetically engineered crops with greater yields. What are the advantages of these crops with greater yields? What are the disadvantages of planting only a single crop? Include a discussion of native land races and genetic diversity in your discussion. With a growing human population, are these genetically engineered crops the best (or maybe the only) option available for feeding the world? (Refer to Chapter 21.)Discuss the ethics of transgenic animals and animal rights. Is there a problem with having pigs cloned and raised solely for the purpose of providing hearts for xenotransplantation? Should entire herds of cloned goats be raised solely to produce human pharmaceuticals? Do these animals have any rights? Should they? (Refer to Chapter 21.)NOTE: Your response should not merely quote or paraphrase the content in the course text. You are expected to analyze and expand upon the information in the text. You are expected to properly cite all sources used to prepare the responses, according to APA formatting guidelines. Each response should be a minimum of 150 words, although top responses will likely be longer. For each discussion forum topic, each student must also respond to a minimum of two classmates’ responses.

pH Scaling: Acids and Bases Lab ActivityComplete the following activity by following the procedure closely. Take notes of observations and questions as you move through the experiment.At the conclusion of your experiment, answer the Analysis questions. Be thorough as you respond to these important questions - your overall Analysis Portion should be three to four pages in length (750-1000 wordsPart I: Essential Questions1. What is the pH scale?2. How are acids and bases measured by a pH indicator?3. How are acids and bases different?4. What types of substances are considered acids and bases?Materials:• Copies of Acid/base lab sheets• pH litmus paper (pH testing strips)• Variety of solutions (lemon juice, vinegar, water, tea, milk, soap, baking soda)• Goggles (Safety Precautions) **Students must wear goggles!• Do not taste or directly inhale any of the solutions.Procedure1. Choose 5 different substances to test.2. Hypothesize whether each substance is an acid or a base. Record on the table below.3. Put each substance in a test well. If it is a liquid, test the liquid directly. If it is a solid, it needs to be mixed with water so the pH can be determined.4. Dip a pH strip into each of the 5 substances and allow it to sit for 10-20 seconds. Using the pH scale on the pH strip container, measure the pH level and record it on the chart.(See attached document)Part II: Data Table: Measurement of pH(See attached document)Name of SubstanceHypothesis (is it an acid or a base?) pH LevelAcid, base or neutral?Part III: Analysis questions:1. What does the pH scale indicate?2. What is an acid? Where are they found on the pH scale? What is a base? Where are they found on the pH scale?3. Were any substances tested neutral? Why or why not? Explain your answer.5. Were any of your results surprising? Why or why not?6. Write five facts you learned about acids and bases."Make sure to show your work and use the correct amount of significant figures. "
