Calculating Force of Friction. #1. BarCode. 1. The problem statement, all variables and given/known data. A car of weight 1500 N has its brakes locked. Calculate the force needed to begin to drag he car on dry asphalt. How will the force needd to slide it along the asphalt compare with the force needed to start sliding it? Why? (Static coefficient=1.2, Kinetic coefficient=0.8) Known: weight (1500 N, the mass in N on earth) , coefficients of static and kinetic friction 2. Relevant equations Ff = (coefficient of kinetic)(normal force) Fn = mg 3. The attempt at a solution (force needed to start it moving) Force of friction = 1.2 * 1500 N = 1800N (force needed to keep it moving) = Force of friction * coefficient Kinetic friction
A psychiatrist has an MD degree (Doctor of Medicine) or DO (Doctor of Osteopathy) and has chosen to specialize in the branch of medicine that focuses on mental health issues. A psychiatrist treats patients by talking with them as well as by prescribing medication (if needed). Psychologists have one of these degrees: PhD (Doctor of Philosophy), PsyD (Doctor of Psychology), or EdD (Doctor of Education). A psychologist treats patients by talking with them but does not prescribe medication.
Report Abuse. Psychiatrists are medical doctors who believe that mental diseases are medical conditions that have a medical explanation and a medical cure. So they will most often prescribe medications because medications are the medical response to a disease.If your interested in other forms of therapy, you can ask about seeing a psychologist, or a therapist. They specialize in treating mental diseases without the use of medicine.ating Newest Oldest. Best Answer: No psychiatrist dont always prescribe medication. I've seen one for a year, and got medicine prescribed to me to help me sleep and one other bottle for bipolar, but they took me off of them since i had an allergic reaction to one.
