Physics lab:9 Equilibrium of parallel force 11/09/2012 By: Camilo Salazar Jillian Ellis Purpose: To understand the conditions need for a rigid body to be in equilibrium when there are forces acting on the body from different sides. Theory: When force is applied on a rigid body for example a ruler it can either be in equilibrium or it can be unbalance. When the force is unbalance what would happen is this motion the body can be either translational or rotational. “A body in translational

Supply and Demand Economists believe they understand and can predict within a certain degree the outcome of general micro and macroeconomic phenomena. Microeconomics is the study of individual choice‚ and how that choice is influenced by economic forces (Colander‚ 2010). Macroeconomics is the study of the economy as a whole (Colander‚ 2010). As much as the regular person would like to ignore these same principles and simply live their lives they will be subjected to the harsh reality of economics

is considered in a state of equilibrium when its properties do not change at time passes. Equilibrium is a state of a reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by

CH 127 – Chem 2 Lab Determination of an Equilibrium constant Goals The purpose of this experiment is to determine the equilibrium constant for the reaction Fe3+(aq) + HSCN(aq) –>FeSCN2+(aq) + H+(aq). The equilibrium constant expression Kc for Reaction is kc=FeSCN2+[H+]Fe3++[HSCN] Procedure *Preparation of the Beer’s law plot Prepare five solutions of FeSCN2+(aq) of known concentrations between 1x10-5M and 1x10-4M by diluting various volumes of 4.62x10-4 HSCN.

The First and Second Conditions for Equilibrium The first condition for equilibrium: The second condition for equilibrium: • • ΣF = 0 ΣΓ = 0 • In when both of these conditions are satisfied in static systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from

The movie Equilibrium directed by Kurt Wimmer‚ and the book 1984 written by George Orwell both explore what would happen when a government has complete control. When you let someone think for you and make all of your decisions‚ you lose what makes you human‚ which is your free will‚ and your ability to make conscious decisions. In both the text and movie they take away human identity to gain control. The key differences are the ways Big Brother and Father seize control‚ and what effect it has on
