Explain why market prices are useful to a financial manager. A market price is the current price at which an asset or service can be bought or sold. (investopedia.com). Market prices are very useful to a financial manager. It helps with financial planning and it reflects the value of the assets based on GAAP (which refers to the Generally Accepted Accounting Principles). GAAP is just a set of guidelines that must be followed when it comes to any type of financial practice. Market price is also a

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

Danielle Perkins September 9‚ 2013 AAPSC 603 Discussion Paper The Factors Affecting Greenhouse Gas Emission in the Livestock Industry People around the world have become very aware of the changes our world is going through on a constant basis. One of the biggest subjects people are talking about is global warming and how the human race is the number one cause of it. In more than one way this is unmistakably true. From the daily activities of driving gasoline powered cars to the simple necessity

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

OIL AND GAS ACCOUNTING: CRITICAL EXAMINATION OF THE APPLICATION OF THEORY TO PRACTICE IN NIGERIA 1.0 INTRODUCTION: The natural resources of a nation‚ particularly the minerals‚ often constitute the lion’s share of the nation’s wealth. This is particularly true of the OPEC nations including Nigeria. Prior to the development of accounting standards issued by the Nigerian Accounting Standards Board (NASB)‚ the financial statements published by the oil and gas industry in Nigeria did not disclose adequate

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
