consideration. There are also many tools that ghost hunters use to sometimes detect if they are there. One of these tools is called an Electromagnetic Field Detector‚ also known as an EMF‚ is the modern day ghost researcher’s tracking device. With this instrument it is possible to locate and track energy sources. It will detect fluctuations in electromagnetic fields and low strength moving EMF fields that have no source. It is a common theory that spirits disrupt this field in a way that you

Identification of Metallic Ions Pre Lab Questions: 4pts 1. What are the learning goals of this experiment? To perform and observe the flame tests of some alkali and alkaline earth metal ion 2. Define ground state and excited state of an atom. Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave

Assignment Q1 Working relationship and personal relationship The basic difference between working relationship and personal relationship is the intimacy or the level of intimacy that people can show. In a personal relationship‚ one can be as sweet or rude as he can be depending upon his mood. However‚ working relationships are more formal‚ and people tend to behave in more or less same fashion all the time. Conversations in working relationships are more businesslike and mostly polite. On the other

What is light produced‚ reflected and refracted into visible light? Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The definition of produced visible light means when the electromagnets radiation meets the human eye. The first example of produced is a glow stick because it produces its own light . Another

gravity on one drop * Charge was applied to falling drops by illuminating bottom chamber with x-rays‚ exciting electrons‚ causing them to attach to oil. * Using a battery‚ electric voltage was applied to the plates. When just right‚ the electromagnetic force would balance out the force of gravity‚ suspending particles in midair. * Noticed charge was always multiples of 1.6 x 10^19 * Q= mg/E Gold Foil Experiment * Radioactive particles (alpha radiation)

According to recent studies‚ there are less than two hundred thousand cases of bone cancer per year. There are three varieties of bone cancer which are called chondrosarcoma‚ Ewing’s sarcoma‚ and osteosarcoma. The most dangerous out of the three is Ewing’s Sarcoma‚ which only seventy percent out of one hundred survive after five years of the diagnosis. Chondrosarcoma is also very dangerous if it has progressed further before treatment‚ making it only a twenty-five percent survival rate after five

Recommendation It is a pleasure to write a letter of recommendation for Mr. Rutwik Reddy Reddy‚ a deserving student‚ for admission to pursue Master’s Degree at your University. I have taught him the courses of “Electromagnetic waves and Transmission lines” and “Optical Communications” .This interaction with him provides me sufficient information to gauge and asses the intellectual capability and analytical skills that he has developed during his course.

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

Naturally aspirated engines versus forced induction engines. Among mechanics and race car drives this subject has been debated since the creation of the forced induction engine. The principle behind the forced induction engine is the use of different types of air compressor called turbochargers to compress the air entering the engine‚ this unit is attached to a naturally aspirated engine and uses the exhaust gases to spin a turbine to compress the air going into the engine.The naturally aspirated

the emission of electrons from a metal surface under the illumination of a suitable radiation. The photoelectric effect is the phenomenon whereby electrons are emitted from a surface (usually metallic) upon the exposure to and absorption of electromagnetic radiation‚ such as visible light‚ that is above the threshold frequency. This is because electrons cannot get enough energy to overcome their atomic bonding. The photoelectric effect furthered wave particle duality‚ whereby physical systems (i
