f 0.0124 J. The object collides with a horizontal spring and compresses it by 0.800 m before it is brought to rest momentarily. What is the spring constant of this spring? When the spring was compressed to 0.800 m, is the work done on the mass m1 by the spring positive, zero, or negative?

irs during primary recovery. This problem explores some aspects of this behavior. Consider the expansion of methane from 300 bars to 50 bars at a constant temperature of 40 C (313 K). Methane obeys the following equation of state V =(RT/P)+C+(D/T) where C = 31 cm3/mol, D = -693cm3K/mole, and R = 83.14bar cm3/mole K. Note that the units of energy are bar-cm3/mole in this problem. Report your answer in bar-cm3/mole (a) What is the change in enthalpy during the expansion (b) What is the change in internal energy? (c) What is the heat removed?

t or add. I'll attach the questions, my rubric, as well as my answers I made. It would really help me out please. The questions: 1.) Choose two somatosensory receptors. Please include a description of each receptor, what they sense, and which part of the brain processes the information from the receptor. 2.) Provide a discussion of the thyroid gland. Include the following: Description of the thyroid gland's structure and location. Description of the cells of the thyroid gland. Description of the hormones secreted by the thyroid gland and their functions. Description of how thyroid hormones are controlled by hormones secreted by the hypothalamus and anterior pituitary gland. Description of how the feedback system works in the cases of high or low thyroid hormone levels. 3. Describe the cardiac cycle. Include descriptions of the 3 phases, the pressure changes in each of the heart's chambers, valves are open and closed, and blood flows during each step. My answer: 1.) Exteroceptor - receives external stimuli from outside of the body. An example, the skin (Thermoreceptors) detects the temperature of the outside area of the body. Interceptor - receives stimuli from inside of the body. An example would be blood pressure as well as blood oxygen levels. 2.) Thyroid Gland is located near the front lower part of the neck, beneath Adam's apple. Its structure includes Thyroid Epithelial that form follicles filled with colloid - a protein-rich reservoir of the materials needed for thyroid hormone production. The cells are responsible for releasing hormones that control metabolism (Energy levels). The thyroid gland releases triiodothyronine (T3) and thyroxine (T4). These hormones regulate weight, energy levels, internal temperature, skin, and growth. When the hypothalamus and pituitary function well, they can detect when hormone levels are low, which causes them to produce more TRH and TSH, which stimulates the thyroid to produce hormones. When the hormone levels exceed their limit, they then have less TRH and TSH, which results in reduced hormone production by the thyroid. Feedback is when a product feeds back into its initial cycle. The Feedback includes both positive and negative feedback. Positive Feedback is when a product provides back to increase production: an example, milk production by a mother for her baby. As the baby suckles, nerve messages from the nipple cause the pituitary gland to secrete prolactin. Prolactin, in turn, stimulates the mammary glands to produce milk, so the baby suckles more. Which causes more prolactin to be secreted and more milk to is made. Negative Feedback is when a product feeds back decreases production; it brings down show if they increase past their limit. It also controls insulin secretion by the pancreas. 3.) The Cardiac Cycle takes place from the beginning of a heartbeat to the next. It contains two periods: One is when the heart muscle relaxes and refills with blood, called diastole, following a time when it begins contraction and pumping of blood, systole. Once emptied, the heart then relaxes and expands to receive another inrush of blood coming back from the lungs and other areas of the body. The atrioventricular valves remain open while the semilunar valves are closed. During the middle part of the diastole, a small amount of blood flows into the ventricles. The blood flows from the veins and passes the atria fills the ventricles. The pressure in both ventricles is close to zero as a result.

what is the change in the internal energy of the system, in J?

audience. This assignment will focus on how criteria can change and how you need to tailor your essay to these changing audiences. In good times, people may want homes with soaring entryways, lots of space and premium appliances. In tougher times, they may care more about efficient use of space, quality insulation, and energy efficient appliances. When gas prices are low, people love to buy SUVs and trucks, but when gas prices get higher, they prefer hybrid cars with good fuel efficiency. Think of two scenarios, much like the ones above, where different audiences or different times create different criteria for evaluation. For example, what impact might global warming have on the way we determine desirable places to live or vacation? How might a changing economy change the way we view successful careers? If people across the globe continue to put on weight, how might standards of beauty change? Si i have this assignment for English I just don't understand it here is the assignment: Explore two scenarios in which change might revise customary values and standards for evaluation. Each scenario should be a paragraph of at least 100 words in length.

llion a fine against Koyo USA Corp. for violations at its Big Island water bottling plant, state officials said Monday. The company, which markets its filtered bottled ocean water in Hawaii and Japan under the band name Mahala Hawaii Deep Sea, paid $1 million to the Health Department on May 2 and must make the second payment by Aug. 31, 2013, health officials said. The Health Department had fined the company $5 million for the violations in September 2011 after an investigation found it had been using an unapproved manufacturing process since 2006. None of the company’s bottled waters was recalled and health officials said there was no threat or risk to human health, as confirmed by test results from independent laboratories and the state lab. Koyo continues to operate its facility at the Natural Energy Laboratory of Hawaii Authority in Kailua-Kona. Statement: The government should fine companies that do not follow procedures. 1. Present arguments (as many as you can think of) in support of the government why it is justified to fine Koyo. 2. Present arguments (as many as you can think of) in support of why Koyo should be allowed to do what it did. 3. What is your position? 4. Should the government be allowed to do this in some industries but not all? Why or why not? WRITE YOUR ANSWER UNDER FOUR CLEARLY MARKED SUBHEADINGS (SEE BELOW) REFERRING TO THE FOUR ABOVE. 1.
