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

STATEMENT OF THE PROBLEM Airphil Express‚ which also has been called PAL express‚ is PAL’s budget airline. PAL’s transfer of its pilots to its budget airline is the alleged reason for the resignation of the pilots. PAL had to beef up its operations in order to compete with Cebu Pacific. However‚ instead of hiring new pilots for Airphil‚ PAL came up with a different strategy. PAL offered the pilots “another job” --- to be pilots but this time for Airphil Express where they would receive lower salaries

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

Management Model‚ it shows how the external audit fits into the Strategic Management Process. Key External Forces External forces can be divided into five broad categories: * Economic forces; * Social‚ cultural‚ demographic‚ and environmental forces; * Political‚ governmental‚ and legal forces; * Technological forces; and * Competitive forces. Relationships among these forces and an organization are depicted in illustration below. External trends and events significantly affect

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
