1.      This exercise asks you to negate various results that are equivalent to the Euclidean parallel postulate. (a)   Alternate Postulate 5.1. Given a line and a point not on the line, exactly one line can be drawn through the given point and parallel to the given line. (b)   Alternate Postulate 5.2. If two parallel lines are cut but a transversal, then the alternate interior angles are equal, each exterior angle is equal to the opposite interior angle, and sum of...

Introduction: Give a brief overall description of PTSD. Describe any shared general symptoms associated with the disorders in this category? Find and share a media example (movie, TV, commercials, etc.) of one of the disorders in the category. Is the media portrayal accurate (or is it based on stereotypes)? For each specific disorder presented, provide the following information: Which model/theory best describes the underlying cause(s) of this disorder and why? (i.e. biological bases of behavior, diathesis-stress, psycho-analytic, etc.) What are...

An Atwood Machine with a massive pulley is set into motion. The geometry of the pulley is a solid disk with an axis of rotation through its center. The pulley’s mass is <0.275 + A/100> kg and has a radius of <0.30 + B/10> m. A mass m1 =< 0.325 + C/1000> kg is hung on one side and m2 = 0.425 kg on the other. They are connected by very strong, massless string!(pulley is frictionless) What is the linear...
