Which relationship between their magnitudes is correct

equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring‚ while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However‚ due to errors in the experiment‚ the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating that all the forces are in

Dehumanization in Kurt Vonnegut’s "Harrison Bergeron." "The year was 2081‚ and everybody was finally equal‚" the story begins. "They weren’t only equal before God and the law. They were equal in every which way"(1354). In this haunting story‚ Vonnegut probably wanted to warn our society of similar kind of equality‚ equality that can be fatal for human race. In this work the theme is only a minor feature and is not really developed. The idea probably intrigued Kurt Vonnegut and forced him to develop

“Making the Grade” by Kurt Wiesenfeld‚ was published in June‚ 1996‚ in the Newsweek magazine‚ explaining the possible threats of grade inflation and cynical grading. After thoroughly analyzing Wiesenfelds article‚ I was astonished at how critical and potentially dangerous it is‚ in the present university grading systems‚ to allow students alleged “potential” to outdo effort and intelligence. Weisenfeld later states‚ “Last year a light tower in the Olympic Stadium collapsed‚ killing a worker. It collapsed

investment‚ and high regulations present significant expenses and hardship for new firms entering. Barriers to entry‚ unlike all other factors in the five forces model‚ actually raises profits in a five forces analysis. This is because high barriers to entry prevent firms that could easily come into the market and take away profits. Other forces such as supplier power‚ buyer power‚ threat of substitutes‚ and industry rivalry‚ have moderate power in this industry. This would usually present a case

Porter’s Five Forces Analysis Diagram 1 Porter’s five forces model (source from Business Resource Software‚ Inc.) The Porter’s five forces model will be used to evaluate information system and automobile industries. Determinants of Entry By entering into car manufacturing market is very costly and risky as the initial costs required a large capital investment on technologies‚ economics of scale and accessibility to distribution channels has restricted the entry of new entrant to the industry

Title: Centripetal Force Tools and Equipments: nylon cord‚ different weighing hanging masses‚ stopwatch‚ meter stick. Purpose: To be able to determine the relationship between centripetal force‚ mass‚ velocity‚ and the radius of orbit for a body that is undergoing centripetal acceleration. To investigate the dynamics of uniform circular motion. Specifically the relationships among the centripetal force‚ the accelerated mass and the radius of rotation. Procedure: THEORY:

SALES FORCE In today’s global marketplace‚ managers face many challenges related to fulfilling the customer’s ever-changing needs and expectations. The concept of customer service has recently become more complex as a result of globalization of goods and services. Customers are now well-informed decision makers as a result of the abundance of information that is available online and in the media. In addition‚ today’s consumer is most concerned with how a salesperson can solve basic problems and

Competitive Forces (Porter’s 5 Forces) Analysis of the competitive environment can be done utilising Michael Porter’s 5-forces model of UPS and FedEx. Porter’s theoretical framework allows us to determine the overall profitability and sustainability within the industry (Laudon & Laudon 2006‚ pg.99; Hubbard 2004‚ pg.211). We reckon that in this case‚ the competitive forces for both UPS and FedEx are very similar because they are both in the same industry. Power of substitutes: Communications
