The ongoing NATO bombing of Kosovo is expected to end soon as peace talks are currently underway, despite some accidental hits on civilian areas. These bombings are seen as justified due to the atrocities occurring in the region. However, Serbian President Milosevic remains resistant to complying with mandates that would stop the bombings. If a […]

Now a days we are using copper wires as they are the most cost effective and reliable interconnect in parallel machines. However as machines grow more powerful, wire density becomes critical making fiber possible alternatives because of their small wire size. Fiber optics are used mainly to use effectively its high bandwidth. On a single […]

Student Exploration Magnetism Vocabulary: attract, bar magnet, ferromagnetic, magnetize, North Pole, repel, South Pole Prior Knowledge Questions (Do these BEFORE using the Gizmo. ) What happens when you place two magnets close together? It depends on the sides when the two North Pole sides are meant then they get pulled together. And if it should […]

There has been a recent increase in the examination of high power density DC/DC converters and technologies, with attention on different areas including topologies, machinery, packaging, and power density. The need for smaller and more efficient products with greater density has greatly increased, resulting in a wide array of choices for power ratings and packaging. […]

In “A&P” by John Updike it is shown that conformism is a major part of society in that time. In the story everything is like a well-oiled machine, but when three girls’ walks into the “A&P” store all of this changes for Sammy. A theme that is predominant in the short story by Updike is […]

Treating actual trauma injuries, healing abscess, attending to people with eye infections, and removing fragments of shrapnel are just some of the duties that I have to carry out as a “doc. ” I was in the US Navy as a medical corpsman for five fruitful years, and my experience thought me that saving another […]

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the […]

The aim of my investigation will be to analyse the relationship between several variables, which are defined by stokes law, and conclusively to apply these in order, to calculate the viscosity of the fluid from my results. To see how successful my experiment was, I will be comparing my results with those from external sources […]

Newton’s First Law of Motion asserts that an object will maintain its current trajectory unless affected by some external force. This principle, elucidated by Sir Isaac Newton, mirrors a personal incident where my direction was changed due to outside influences. In my teenage years, I would persistently adhere to my own plans, often ignoring advice […]

1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and […]

Observing Mechanisms Introduction A mechanism is a device that transmits movements so that the output movement is different than the input movement. It can be used to change the direction, speed, force, or type of movement. The output of a robot or any machine is motion and force in some form. A drill press, for […]

Nuclear Force The atomic nucleus contains a mix of protons and neutrons. The electrons are arranged around the nucleus. We already know that the protons have a positive charge and they have to repel each other because of Coulomb’s law: If the protons have to repel each other why it doesn’t happen? Answer is the […]

ABSTRACT  One of the challenging factor in factories, for the proper functioning of the machine for the long duration with efficiency is to keep certain parameters within a specific range. Thus, in this paper, we have designed a ladder diagram for running PLC with the objective to automatically control the hydraulic system. Our main requirement […]

Introduction Newton’s third law of motion states that force occur in pairs. It also states that every action has an equal and opposite reaction. This means that for every force applied on an object, there is an equal force in magnitude which is operating in an opposite direction. During the interaction of two objects which […]

Topic #1: Newton’s Laws Newton’s Laws consist of three laws that describe motion. The first law states that an object in motion will remain in motion unless acted upon by an unbalanced force, and that an object at rest will remain at rest unless acted upon by an unbalanced force. This law relates to the […]

Motors and generators are the most frequent used electrical machines. Generators action can take place when and only when, there is a relative motion between conducting wires and magnetic lines of force. Electric motor is in operation when it is supplied with electrical energy and develops torque, that is, a tendency to produce rotation. In […]

In the early power systems were mainly Neutral ungrounded due to the fact that the first ground fault did not require the tripping of the system. An unscheduled shutdown on the first ground fault was particularly undesirable for continuous process industries. These power systems required ground detection systems, but locating the fault often proved difficult. […]

Forces Science helps us understand the connection between forces and how they impact our daily lives. Forces are essential to our everyday existence. Force is crucial for the movement, stoppage, or change in direction of all objects. These forces can be in the form of pushing, pulling, or twisting. As per Newton’s first law, an […]

Electricity and magnetism are both forms of the electromagnetic force. This force can be produced by rotating coils of wire near a magnet. When objects are moved towards or away from each other by a force, it is referred to as electricity. Earth and other planets also function as magnets. The earliest magnets were constructed […]

Consider the broad shifts in marketing. Can they be related to the major societal forces? Which force has contributed to which shift? Answer: According to Kotler and Keller (2011), marketing is the ability of an organization to be able to meet the needs of its markets profitably. In the bid to profitably meet the needs […]

A ship sailing on the open sea leaves Port A for Port B at a bearing of N25oW. A wind of 6 km/h on a bearing of N10oE blows the ship off course. If the ship is capable of 35 km/h in still water, find the new speed and direction relative to the shore.  A […]

The secondary resistance of a protective transformer is lower compared to that of a measuring transformer because measuring transformers are used to measure currents at normal operation, which typically flows small current in a small range of currents. On the other hand, protective transformers are used to measure currents at fault conditions, where the drawn […]
