Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…
What chracterizes the axial flow turbine is its rotation axis. It could be placed vertically or horizontally to water surface. In this latter type the axis is parallel positioned to the incoming water stream. Also the generator can be submerged under water or non-submerged. This turbine is usually used as tidal energy converter. For small river use, the axis could be an angle inclined to the water stream. See figure \ref{Hydro_HorizontalAxis}. Hydrokinetic converters with a vertical axis…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…
Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx. F stands for the load added to spring, k is spring constant and x stands for…
Model Scenario During recess on a sunny August afternoon, I noticed several of my students gathered together on the sidewalk. I walked over to see what the fascination was about, and found that one of the students had several types of magnets and other materials. The students appeared to be genuinely interested in discovering what would and would not attract to the different types of magnets. Once we returned to the classroom, several students made statements about characteristics and…
Wheatstone bridge is a device used to measure unknown resistance by passing current through the resistor [1]. Wheatstone bridge is made up of a power source and galvanometer that joins the two-parallel circuits which contains two resistors each. It is very useful in finding small resistances and is used in various applications such as strain gages. The following figure shows the arrangement of a Wheatstone bridge. Figure 1: Arrangement of a Wheatstone Bridge [1] Importance of Wheatstone…
Magnetism is when an object has a magnetic force, field, or a pull on another object.Temperature plays a large role in the strength of magnetism, and more importantly how a magnet reacts towards temperature. One can describe temperature as how hot or cold an object is. Temperature is ultimately how fast the molecules in an object are moving. The faster the molecules in an object are moving, the more heated the object becomes. Magnetism is when an object has a magnetic force, field, or a pull…

metal. By tapping into the power of magnetism, an invisible force that pulls things together or pushes things apart, he can throw cars and move buildings all with the flick of a finger. The Earth itself also happens to be one big magnet, creating a magnetic field, or type of force field, that extends miles beneath the Earth’s surface and into space. Now, split campers into 8 groups of 3 or 4, giving each group two magnets. Have campers hold the magnets close together. What happens? Can they…
