An electron gun fires electrons into a magnetic field directed straight downward. Find the direction of the force exerted by the field on an electron for each of the following directions of the electron’s velocity: (a) horizontal and due north; (b) horizontal and 30° west of north; (c) due north‚ but at 30° below the horizontal; (d) straight upward. 2. (a) Find the direction of the force on a proton moving through the magnetic fields in Figure 1‚ as shown. (b) Repeat part (a)‚ assuming the moving

How competitive forces shape strategy Pflicht 4. (5Forces) " 1 von 3 While one some- times hears executives complaining to the contrary‚ intense competition in an industry is neither coincidence nor bad luck. Moreover‚ in the fight for market share‚ competition is not manifested only in the other players. Rather‚ competition in an industry is rooted in its underlying economics‚ and competitive forces exist that go well beyond the established combatants in a particular industry. Customers

The officer believes that one of them might be responsible for a string of recent burglaries. The teens are questioned‚ and the officer becomes angry at their responses. Over the objections of the teenagers‚ both teens are pulled out of the car and shoved around a little. They are both told that they are under arrest

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

questions: force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

In the past 30 years‚ Porter’s five forces model has been recognized as one of the most useful strategic management tools which can be used to analysis organization external environment‚ so as to help organization build up competitive advantages. However‚ with the development of the world‚ the five forces model has been challenged that it cannot be continued use to adapt today’s dynamic environment. This essay aims to challenge Porter’s five forces model and to identify the problems which hide behind
