READ MOREBrushless DC Motors are an important class of highly efficient electric motors. They are most frequently used in electric vehicles because of their high efficiency and high power density. They are also present in the small DC fans used in power supplies and CPU coolers. In order to discuss the Brushless DC Motor it is important to first have a basic understanding of the more common Brushed DC Motor which is present in many household items. The brushed DC motor consists of a rotor (the

2.1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2.1.1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field‚ thumb points in DC direction and palm points to direction of the force. 2.1.2 Factors affecting the force acting on the current-carrying conductor Forces are experienced by the electrons in the conductor

Piaget’s Theory of the development of children Have you ever thought of how a child’ mind works and how they learn? Well Jean Piaget has‚ he developed the theory that all children learn through four different stages of development. The stages he unveiled are; sensorimotor‚ preoperational‚ concrete operations‚ and formal operations. He believes that each stage is just built on the previous‚ and I highly agree with this theory of development. Each stage he developed is also arranged into an age sequence

ask them questions it shows them you were paying attention. My theory is you learn faster when you observe and when things are hands on. Everyone has there own way of learning ‚ not everyone is the same. Observation is to become familiar with the insiders to refine and subsequent observation and data collection. It has become aparent to me in the past few months that most people are not really thinkers‚ but are more observers .One who doesnt understand their learning style is never really learning

General Motors was founded in September of 1908 by William Durant during a time that there were less than 8‚000 in the United States. Durant was already known in Flint‚ Michigan for his horse drawn vehicles. “At its inception GM held only the Buick Motor Company‚ but in a matter of years would acquire more than 20 companies including Oldsmobile‚ Cadillac‚ and Oakland‚ today known as Pontiac.”(History & Heritage-Creation‚” 2014) General Motors set the tone in the automobile industry with design

Some children may suffer from or be more prone to a condition that may make progress difficult. Some conditions that children are born with such as diabetes or a blood condition affect children from early on and have sever ramifications on their lives from birth. Other conditions may appear later‚ such as asthma‚ which children are more susceptible to if they live in areas where the air condition is poor‚ they live in damp conditions or whose parents smoke. These conditions and many others have an

important for a child to engage in creative play during their development.The main reasons to support this claim is for children to express themselves freely‚become independent thinkers‚and better interact with peers.These three reasons all support the fact that creative play is more important and needed for a child’s development. The first reason why it is more essential for a child to be a part of creative play is to express themselves more freely."Children need the freedom to choose activities
