Description
As shown in the diagram, a 4800-kg cable car is descending a high hill. A counterweight of mass 4600 kg on the other side of the hill aids the brakes in controlling the cable car's speed. The rolling friction of both the cable car and the counterweight are negligible. How much braking force does the cable car need to descend at constant speed?

Anatomy Assignment
Maria was tired of not feeling like herself and tired of being so stressed about it. She was particularly tired of how her eyes seemed to bulge outward, so much that her friend, Matt, had started calling her “Bug Eyes.” Dr. Jollo looked at Maria and said “Well, your blood pressure and pulse are elevated. You’ve lost weight without trying, you have difficulty sleeping, you perspire more than usual and you’ve had continuing bouts of diarrhea. Those things, combined with the swelling in the front of your neck, suggest that you may be suffering from more than the stress of college life. I think we need to run some blood tests to check your thyroid function.” Maria blinked in surprise. “All of those things can be caused by a problem with my thyroid? Even the way my eyes look?” Dr. Jollo nodded. “Your thyroid secretes several hormones that have widespread and varied effects. The protrusion of your eyes is a condition called exophthalmos – it is an inflammatory response to abnormal levels of thyroid hormones. The fact that you have this condition in addition to your other symptoms makes me fairly certain this is a thyroid problem.” Maria hoped Dr. Jollo was right. Having a medical explanation for her symptoms would mean that she wasn’t losing her mind. Several days later, Maria met again with Dr. Jollo. “Let’s talk about your test results,” he said. “Your thyroid hormone levels are elevated, but your level of thyroid-stimulating hormone (TSH) is lower than it should be. Those results suggest that you probably have Graves’ disease, which means that your thyroid is overactive. But there’s good news too—this is a condition that we can treat relatively easily.” Maria felt a twinge of relief at the doctor’s words, but a flurry of questions poured out of her mouth. “What made my thyroid go crazy? And what is TSH? If it’s a thyroid hormone, why is it low instead of high like everything else? And what kind of treatment do I need? Will it fix my thyroid? Will I…” Dr. Jollo laughed and held up his hand to stop the barrage of questions. “Hold on, Maria. I’ll explain everything, and with the right treatment, your friend may not be able to call you ‘Bug Eyes’ much longer.”Questions1. Name the two hormones commonly referred to as “thyroid hormone” and describe their general actions.2. Why would an overactive thyroid cause Maria’s weight loss, sweating, and elevated heart rate?3. Maria wonders if TSH is a “thyroid hormone,” and Dr. Jollo explains that it is not. State the action of thyroid-stimulating hormone (TSH) and name the gland that secretes it.4. How is the secretion of TSH regulated under normal conditions?5. Why is Maria’s TSH level low instead of high?6. If Maria had been diagnosed with hypothyroidism, what would happen to her levels of TSH and thyroid hormone?7. A common treatment for Graves’ disease involves ingesting a dose of radioactive iodine, which slowly destroys the thyroid gland. Why are other tissues unaffected?All reports will be worth 4% of your grade and will be 5 points each. In order to successfully earn all 5 points you will need to:1. Answer all questions thoroughly and completely.2. Use at LEAST 3 different references (can include information from the Primal website as a source). The references needs to be listed in a "Works Cited" section at the end of the report. Please note: Wikipedia does not count as a reference. 3. Give credit to all sources used- citing correctly and PARAPHRASING any information taken from an outside source. Please do not copy and paste any information, even if you cite the source. Your report will be submitted through Turnitin and will allow us to see what sources were used and the exact information you took from that source- BE CAREFUL!4. Must have a minimum of 500 words and can be in essay form OR question and answer form. (500 words not including the topic/questions given)

RSCH 8110 Walden University Representation of Probability Sampling Discussion
Discussion: Sampling and Collecting Quantitative and Qualitative DataIt is often not possible or practical to study an entire population, so researchers draw samples from which they make inferences about a population of interest. In quantitative research, where generalization to a population is typically valued, a researcher’s ability to make such inferences is only as good as the sampling strategy she or he uses to obtain the sample. Once an appropriate sample has been obtained, data collection should involve valid and reliable measures to ensure confidence in the results, as well as the ability to generalize the research outcomes. Although generalization is typically not a goal in qualitative research, sampling is just as important in qualitative and mixed methods research, as is obtaining reliable and valid results. Indeed, for quantitative, qualitative, and mixed methods research, sampling strategies and accurate data collection methods are critical aspects of the research process.Specific methods of data collection (e.g., surveys, interviews, observations) produce specific types of data that will answer particular research questions, but not others; so here too, as covered in previous weeks, the research questions inform how the data will be obtained. Furthermore, the method used to collect the data may impact the reliability and the validity of that data.For this Discussion, you will first consider sampling strategies. Then, you will turn your attention to data collection methods, including their strengths, limitations, and ethical implications. Last, you will consider measurement reliability and validity in the context of your discipline.With these thoughts in mind, if your last name starts with A through L, use Position A. If your last name starts with M through Z, use Position B.Position A: Probability sampling represents the best strategy for selecting research participants.Position B: Nonprobability (or purposive) sampling represents the best strategy for selecting research participants.By Day 4Post a restatement of your assigned position on sampling strategies. Explain why this position is the best strategy for selecting research participants. Support your explanation with an example and support from the scholarly literature. Next, select a data collection method (e.g., surveys, interviews, observations) and briefly explain at least one strength and at least one limitation. Then, identify a potential ethical issue with this method and describe a strategy to address it. Last, explain the relationship between measurement reliability and measurement validity using an example from your discipline.Be sure to support your Main Issue Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.
