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).

The electric field depicts the surrounding force of an electrically charged particle exerted on other electrically charged objects. The concept of an electric field was introduced by Michael Faraday. The electric field is a vector field with SI units of newtons per coulomb (N C−1) or‚ equivalently‚ volts per metre (V m−1). The SI base units of the electric field are kg⋅m⋅s−3⋅A−1. The strength or magnitude of the field at a given point is defined as the force that would be exerted on a positive test

Five force model of PIXAR Threat of new entrants: High Advanced technologies make it difficult for new competitors to enter the market because they have to develop those technologies before effectively competing. The requirement for advanced technologies positively affects PIXAR. The PIXAR has a high level technology development department‚ so the threat of new competitors is the technology. Threat of substitute products or services: Moderate I consider substitute products to be theater or

the key characteristic of the U.S. Air Force became its airlift capability. Saying that‚ the Air Force became essential element in joint military operation supporting one of the joint functions such as sustainment. Sustainment gives necessary ability to joint forces to maintain and prolong operations until mission accomplished. Moreover‚ the ability of the Air Force to provide by air material and personnel in the theater of military actions gives to Joint Force Command (JFC) flexibility and the ability

domestic markets but are capable of achieving market share in foreign markets. In the fourth quarter of the PC market in 2006‚ the U.S. domestic industry recorded 3% unit growth. Although the industry is providing positive numbers‚ it is controlled by 5 key manufacturers that construct a barrier to entry for smaller computer manufacturers. Each firm has strong brand names and has the right mixes of resources and capabilities. Small firms lack the resources and capability of acquiring enough capital

= 300g 9.8 3. Explain the effect of mass on Hooke’s Law. Hooke’s Law states that the restoring force of a spring is directly proportional to a small displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring

Types of Forces Used in Basketball Forces are found everywhere‚ but of course‚ you can`t see them. They act on you for example if you are waking there are many forces that act`s on you. If they are not involved you can`t wake. Let`s talk about the forces that are involved in basketball. Basketball is a very enthusiastic sport and you must try it‚ you are not going to regrets. Basketball has original thirteen rules‚ but I am just going to mention 10 of them. 1- The ball can be thrown in any direction

Five Forces Analysis What is it? Five Forces Analysis is a tool that enables managers to study the key factors in an industry environment that shape that nature of competition: (1) rivalry among current competitors‚ (2) threat of new entrants‚ (3) substitutes and complements‚ (4) power of suppliers‚ and (5) power of buyers. When do we use it? In a strategic analysis‚ Five Forces Analysis is an excellent method to help you analyze how competitive forces shape an industry in order to adapt or
