Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded

The Five Forces Framework and Competitive Strategy In this framework due to Michael Porter there are two high-level stages in the creation of competitive strategy‚ each stage corresponding to a high-level determinant of profitability mentioned in the previous section. The first stage is the assessment of the attractiveness of the industry in which a given company is embedded based on a structural analysis of the industry. In this stage‚ called the five forces framework‚ five forces that influence

Rivalry among existing firms(competitors) Competitiveness of enterprises and the current does not play a very important role in Disney’s external business environment. That is true‚ the company’s very high exit barriers. In addition‚ the ability to increase in a very large investment. Therefore‚ there is no strong direct competitors Disney’s business. Competitors‚ such as "Lonely Tunes" retail stores bear the expensive advertising to gain market share.

officers have is their power to decide when to use force or when to use lethal force. Manning (1997) argues that it is generally accepted that police should be allowed to use force. He also explains that there are an uncertain amount people who agree on as to what constitutes excessive force. The line between what is necessary and what is extreme is very thin and hard to see. Use of force is no doubt one of the most important aspects in policing and force should also be used with great discretion. The

"The Force Table" is a simple tool for demonstrating Newton’s First Law and the vector nature of forces. This tool is based on the principle of “equilibrium”. An object is said to be in equilibrium when there is no net force acting on it. An object with no net force acting on it has no acceleration. By using simple weights‚ pulleys and strings placed around a circular table‚ several forces can be applied to an object located in the center of the table in such a way that the forces exactly cancel

A force is required in uniform circular motion.Centripetal Force & AccelerationSince an object in motion will travel in a straight line (Newton ’s First Law) an force must be required to accelerate the mass . This force does not cause a change in velocity as stated in the introduction‚ but rather it is responsible for the change in direction. The centripetal
