Solution: mass = 10 kg ; horizontal force (P) = 50 N ; frictional force (f) = 25 N By Newton’s Second Law of Motion: F = ma P - f = m*a ---? 50 - 25 = m*(10) ---? 25 = 10*a Dividing each side by 10 ---? a = 2.5 m/s2 2. Solution: (a) frequency = 3 cycles / sec (based on the given) (b) wavelength = 2 meters (given) (c) speed = wavelength * frequency = (2 m.)*(3 cycles / s) ---? speed = 6 m/s 3. Solution: First, find the rate constant ‘k’ ---? k = = ---? k = 0.2235 Applying A = A0 e –kt where A0 - initial amount and A - amount at any time (t , min) At A0 = 1.0 gram and t = 9.3 minutes A = (1.0) ---? A = 0.1251 gram 4. Solution: Since V = I*R where V = 6 V and R = 10 ohms Then, current I = V / R = ---? I = 0.6 Ampere and power, P = I2R = ---? P = 3.6 Watts 5. Solution: pH = - log [H3O+] = - log (1.0 x 10-5) ---? pH = 5.0 Since the pH is below 7.0 (neutral), then the solution is ACIDIC. pH + pOH = 14 ---? 5.0 + pOH = 14 ---? pOH = 9.0 pOH = - log [OH-] so that [OH-] = = [OH-] = 1.0 x 10-9 M 6. Solution: (a) Start balancing atoms other than O atoms 2 Ni + 3/2 O2 ---? Ni2O3 Then get rid of fraction coefficient(s) by multiplying each by 2 4 Ni + 3 O2 ---? 2 Ni2O3 (b) Start balancing with HF, then HBr F2 + 2 HBr ---? Br2 + 2 HF Essay Section (Answer 8 Questions) Complete these answers in your own words. Follow instructions in the Final Examination document. Answer all questions according to the instructions. Number each question here according to its number in the Final Examination document provided by your instructor. 1. How would you explain the difference between kinetic energy and potential energy? Give an example from the real world where potential energy is transferred to kinetic energy. Kinetic Energy (KE) is the energy associated to the body or object in motion whereas Potential Energy (PE) is the energy stored in a stationary particle or system based on its position, specifically height. One concrete example of conversion from potential to kinetic energy is an automobile at rest on top of a hill is driven down the slope so that it is set in motion which may vary over time when the driver decides to increase or decrease its speed. 2. How would you describe the differences between heat, temperature, and thermal energy? Give examples of how each term is used. Temperature is an intensive property and a measure of hotness or coldness of an object or body of particles. On the other hand, heat is referred to as an energy transfer that takes place due to temperature difference while thermal energy is r egarded as an internal energy of a thermodynamic system. Heat flows from a region of higher temperature to a region of lower temperature and without a change in temperature, no heat is shifted. As an energy established within the system, moreover, thermal energy may either increase or decrease when work is done by or on the system and similarly, when heat is absorbed by the system or released on the

Health care services and mental health services Research Paper

Health care services and mental health services - Research Paper Example Mental health promotion and mental illnesses’ diagnoses and treatment are essential components of family medicine in the American health care. Family physicians receive continued medical education and residency training in order to better manage mental health problems in people of all age groups. Early recognition of problems is made possible with the help of continuity of care inherent in the family medicine. Family physicians are best-suited to recognize the problems and make adequate interventions in the family system since they treat the whole family. Family physicians are particularly important because they are also in a position to give treatment to the individuals who tend to avoid the traditional mental health services due to social stigma linked with the treatment of mental illnesses. Many mental health issues are neither recognized frequently nor they are treated adequately. Therefore, mental illnesses’ recognition and treatment are some of the significant challenges for the primary care physicians that are responsible for most services related to mental health care. Results of a national mental health care survey suggested that up to 18 per cent of the people surveyed with or without a mental health disorder DSM-IV’s diagnosis were treated in a one year period and 52 per cent of the visits took place in the sector of all primary care or general medical care (Pincus et al., 1998). Primary care patients with a psychiatric disorder are between 11 per cent and 36 per cent (AAPF, 2015) and a survey of mental health conditions in the practices of urban family medicine suggests that more than 40 per cent of the research participants met the conditions set for a mental health disorder (National Ambulatory Medical Survey, 2008). Traditionally, mental health services are carved out by the managed care organizations from the primary care. They place the mental health services in
