Introduction to prevent electrical fire:
Electrical problems are a major cause of fires in the United States. These fires cause hundreds of deaths and injuries. The property lost in electric fires per year is worth more than 800 million dollars. I like to share this Magnetic Dipole Moment Equation with you all through my article.
Causes of Electric fires:
Electric fires are caused mainly by faulty wiring, problems in cords and plugs, overloading or otherwise misusing circuits, and poor maintenance of electric wires and appliances. Electric stoves, heating units, television sets, and dryers are some of the appliances that can cause electric fires. There are more fire accidents in the winter months as there is an increase in the electric power spent for heating and lighting.
Having problem with Power Formula Physics keep reading my upcoming posts, i will try to help you.
Preventive Measures:
To prevent electric fires, it is necessary to follow a few precautions.
Check wires and appliances periodically for frayed wires and other damage. Replace frayed wires before you use the circuit or appliance again. Switch off lights if they flicker, or if the light switches feel hot.
Always call a trained professional to do electrical replacements and repairs.
Keep all appliances away from water as water can conduct electricity. Be very careful when using electrical appliances in the kitchen or bathroom, as wet floors and counters can be dangerous.
Keep any appliance that produces heat (such as room heaters or stoves) away from clothes, curtains and other combustible materials. There should be a gap of at least three feet.
Use plugs only with the appropriate outlets. Avoid pushing three-pin plugs into two-slot outlets, or connecting them directly to extension cords. Do not overload sockets or extension cords.
Buy only electrical appliances that have been tested by a nationally recognized laboratory like Underwriters Laboratories (UL)
Check electric tools for frayed or cracked wires and other signs of wear like worn out insulation, and replace them. If any tool causes shocks (however small), heats up too quickly, gives off smoke, shorts out, or gives off sparks, replace it immediately.
Keep children away from electrical appliances and childproof electric outlets by installing safety sockets.

Potassium Nitrate Gunpowder
Gunpowder is also known as black powder, which is a mixture of sulfur, charcoal, and potassium nitrate. The gunpowder can be made by using charcoal and potassium nitrate but if we do not use sulphur, the powder is not as strong.
Introduction to potassium nitrate gunpowder:
Potassium Nitrate Gunpowder burns rapidly and produces a volume of hot gas which is made up of carbonic acid and nitrogen, and solid residue of potassium sulphide. Gunpowder has been used as a propellant in fire alarms and as a pyrotechnic compositions in fireworks because it has the burning properties. Having problem with Permanent Magnet Motor Design keep reading my upcoming posts, i will try to help you.
Characteristics of potassium nitrate gunpowder:
Potassium carbonate is a white bitter tasting substance which is used in gunpowder as an oxidizing agent. It is produced by the action of microbes in soils which contains potash and nitrogenous organic matters and forms efflorescence upon the surface. Its main use is the making of gunpowder.
Potassium nitrate is the most essential ingredient in terms of bulk and function because oxygen is released in the combustion process from the potassium nitrate, which promotes the rapid burning of other ingredients. The potassium nitrate which is present in the gunpowder, supplies oxygen for the reaction.
The three ingredients which are present in gunpowder, are finely ground and mixed, and for this charcoal are not suitable. The crude potassium nitrate is dissolved in boiling water, filtered and allowed to cool and crystallize in a trough. It is done for the purification from nitrates of soda and lime. There is also gunpowder which is termed as prismatic.
The explosive power of gunpowder is very high. Please express your views of this topic Power Formula by commenting on blog.
Action of Gunpowder:
When nitrates are heated, it has the property to release oxygen, and this oxygen leads to the fast burning of sulfur and carbon. This results an explosion like chemical reaction when gunpowder is ignited. When carbon is burned, it consumes oxygen and produces heat and even more oxygen, etc. The presence of nitrates is important to gunpowder composition because the oxygen which is released from the nitrates exposed to heat makes the burning of sulfur and carbon faster resulting explosive action.

Different Types of Sounds
Sound insulation is not to be confused with sound absorption - they serve two different functions. This article covers sound insulation materials and the different types of sound insulation that can be used to effective reduce the transmission of sound energy.
When you soundproof a room you can either do it to reduce noise, which is nothing more than blocking sound waves by using distance or objects to block its passage; or you can use noise absorption, which transforms sound waves by suppressing echoes, resonance and reflection. The insulation materials have damping characteristics, which controls the sound levels, reducing and distorting them.
Sound insulation on the other hand is the prevention of the transmission of sound; a reduction in the transmission of sound energy to the adjoining air space. There are several different types of sound insulation materials that can be used to reduce noise and the transmission of sound.
A brief look at the different types of insulation materials will be helpful in making informed decisions for your home.
You can use fiberglass insulation inserted between the studs in drywall layers as well as foam insulation that can be blown into the wall without removing the drywall. The same methods can be used for flooring as well.
You can use the passive absorption method to reduce sound; mineral wood insulation or acoustic foam forces sound wave to change direction several time and travel a great distance before it can completely pass through the insulation material. Each time the waves change direction part of the energy gets absorbed by being converted to heat.
Lead sheets are very good at blocking sound transmission; in addition they are easy to work with, cut and install. Foil faced acoustic pipe wrap can be used to muffle sound from noisy pumps, generators, engines, saniflow systems, etc. Acoustic mineral wool is very useful in reducing airborne noise and can be used quite successfully in walls, suspended ceilings and flooring joists. The density of the material makes it an efficient sound absorber.
It is recommended that you do a complete research on the subject before attempting to use sound insulation materials.
Firstly, to download SFX, you might first look at what sound designers call "hard sound effects". "Hard sound effects" are clear crisp sound effects like people firing guns, breaking sounds, or a front door slamming shut. Many people also download SFX that are called "ambient" or "background sound effects". Background sound effects don’t necessarily synchronize with any specific movement on screen, in a film or in a PowerPoint production but provide ambiences to the people watching such as forest sounds, crowds at a ball game, or an oven running.
Thirdly, if you want to download SFX that make your production as professional as the feature films, you’ll be looking for something called "Foley sound effects". Foley sound effects can be sound effects that are difficult to record as they take critical timing; a famous example of Foley sound effects are footsteps.
Finally, you might want to download SFX what are called "design sound effects". Design sound effects are normally considered futuristic sound effects and are often used in science fiction films. These sound effects are not what one would normally call "realistic" sound effects, but are sound effects that incorporate some kind of musical aspect to them.
It is important that you remember all downloadable sound effects come in different qualities, such as either 16 bit or 24 bit (higher quality), so make sure to determine what kind of sound effects you want before you go ahead and download SFX.

Building Heating System
Introduction to building heating system
In ancient, time the building heating system used in the Roman Empire. In this empire they used centralized heating system. In the centralized heating system, the hot air circulates through the empty spaces under the floors and the walls in the pipes. In Korea, the same system was installed in the buildings. In Korea the people used stoves to keep the rooms warm. After some time the pipes are installed under the floor and then connected to the furnace rooms so that the whole building get warmed. This system for warming is used in the bathrooms to keep it warm. Now these days we use radiators to keep the room warm. Is this topic Definition of Electromagnet hard for you? Watch out for my coming posts.
Concept Building heating system
The central heating system gives the warmth to the whole building or some part of the building from one location in the building to the multiple locations in the building. The central heating system of the buildings is different from the single room heating systems. It is a like a furnace room in a house and the mechanical room of heating in the whole building. We use the fossil fuel or the boiler to get the heat energy. The heat energy developed in the furnace is transferred in every corner of the building via circulating the air or circulating the hot water in the tubes or in the pipes. Generally, now we use the water because the specific heat of water is too much high, so if we take very less amount of water it contains maximum amount of heat. In the USA, people generally use the natural gas to keep the building warm. I like to share this Formula for Displacement with you all through my article.
Advantages of building heating system
As the central building heating system installed at only one place or at one location in the building so it consumes a very less space. In this system, we use water for heating the room and we use air, air is a bad conductor of heat. As the air warms to a very high temperature, the temperature of the air maintains for a very long time due to the very less conductivity against heat. Air is the very cheap or almost free of cost. Similarly, water has high specific heat and almost very cheap so we use water in the heating systems of the buildings.

Analog Communication
Defination of Analog Communication:
Analog Communication is a data transmitting technique in a format that utilizes continuous signals to transmit data including voice, image, video, electrons etc. An analog signal is a variable signal continuous in both time and amplitude which is generally carried by use of modulation.
Analog circuits do not involve quantisation of information unlike the digital circuits and consequently have a primary disadvantage of random variation and signal degradation, particularly resulting in adding noise to the audio or video quality over a distance.
Data is represented by physical quantities that are added or removed to alter data. Analog transmission is inexpensive and enables information to be transmitted from point-to-point or from one point to many. Once the data has arrived at the receiving end, it is converted back into digital form so that it can be processed by the receiving computer. I like to share this inelastic collision formula with you all through my article.
Comparison of Digital and Analog Communication
Analog communication systems, amplitude modulation (AM) radio being a typifying example, can inexpensively communicate a band-limited analog signal from one location to another (point-to-point communication) or from one point to many (broadcast). Although it is not shown here, the coherent receiver provides the largest possible signal-to-noise ratio for the demodulated message. An analysis of this receiver thus indicates that some residual error will always be present in an analog system's output.
Although analog systems are less expensive in many cases than digital ones for the same application, digital systems offer much more efficiency, better performance, and much greater flexibility. Please express your views of this topic Magnetic Moment of an Electron by commenting on blog.
Efficiency: The Source Coding Theorem allows quantification of just how complex a given message source is and allows us to exploit that complexity by source coding (compression). In analog communication, the only parameters of interest are message bandwidth and amplitude. We cannot exploit signal structure to achieve a more efficient communication system.
Performance: Because of the Noisy Channel Coding Theorem, we have a specific criterion by which to formulate error-correcting codes that can bring us as close to error-free transmission as we might want. Even though we may send information by way of a noisy channel, digital schemes are capable of error-free transmission while analog ones cannot overcome channel disturbances; see this problem for a comparison.
Flexibility: Digital communication systems can transmit real-valued discrete-time signals, which could be analog ones obtained by analog-to-digital conversion, and symbolic-valued ones (computer data, for example). Any signal that can be transmitted by analog means can be sent by digital means, with the only issue being the number of bits used in A/D conversion (how accurately do we need to represent signal amplitude). Images can be sent by analog means (commercial television), but better communication performance occurs when we use digital systems (HDTV). In addition to digital communication's ability to transmit a wider variety of signals than analog systems, point-to-point digital systems can be organized into global (and beyond as well) systems that provide efficient and flexible information transmission. Computer networks, explored in the next section, are what we call such systems today. Even analog-based networks, such as the telephone system, employ modern computer networking ideas rather than the purely analog systems of the past.

Examples of Physical Changes
Introduction to examples of physical changes:
A physical change as the name suggests, brings about a change in the physical state of matter under suitable conditions. Few characteristics associated with physical changes are following:
1. A physical change involves a change in the physical state of a substance by changing either the interparticle spaces or interparticle forces.
2. There is no change in the composition of the substances during the physical change.
3. The substances undergoing physical changes do not change their main characteristics.
4. No new substance is formed during physical change.
5. The change is temporary and can be reversed by reversing the conditions which bring about the change.
I like to share this Formula for Impulse with you all through my article.
Examples of Physical Change :
The change of state of ice to water and then to water vapours is because of these changes which occur upon heating. These get reversed when the vapours are cooled. In all the three states, water does not change the color of either blue litmus or red litmus. This means that it is neutral towards litmus paper. Even when water is mixed with other substances, it mixes without any energy changes. So, it can be separated by suitable means. Hence, it is physical change.
Melting of wax is another example of physical change. These change occurs upon heating. The process can be reversed by reversing the condition which bring about the change. No new substance is formed in the process. It is a temporary change. The substances do not change their composition during the process.
Dissolution of salt in water is also a physical change. This process too, is temporary and it can be reversed. There is no change in the composition of the substances used. No new substances are formed. The mixture shows the properties of its constituents. Please express your views of this topic Electromagnetic Spectrum Wavelength Chart by commenting on blog.
Mixing of Iron filings and sulfur is another example of physical change. There is no change in the composition of the substances during the physical change. The change is temporary and can be reversed by reversing the conditions which bring about the change. The substances undergoing physical changes do not change their main characteristics.

4 Types of Matter
Introduction to 4 types of matter:
Matter is a general term that is used for the substance from which all physical objects are made. Matter includes the atoms and other particles which will have the mass. The common way of defining the matter is that it has mass and occupies certain volume.Matter commonly exists in four states called as solid, liquid, gas and plasma.
Explanation to 4 Types of Matter(solids & Liquids)
Solids: Solid is one of the four common states of matter. solids have definite shapes unlike liquids and gases. The solid keeps its own shape where as if we pour some water into a glass or fill any balloon with gas, the liquid or gas takes the shape of the container which they used.
Liquids: Liquid is one of the four common states of matter. A liquid does not have any fixed shape or size as a solid but the liquid takes the shape of a container that is used. Liquids flow from one place to another. Unlike a gas, a liquid will have a distinct surface called as free surface. By taking an example, water present in a glass has a surface where water ends and the air above it begins.
Explanation to 4 Types of Matter(gases & Plasma)
Gases: Gas is one of the four common states of matter. In Earth's atmosphere the air is mostly a mixture of different types of gases. Usually a gas has much lower density than a solid or liquid. The quantity of gas doesn't have a specific shape just as liquid but different from solid. If a gas is enclosed in a container then it will take the shape of the container same as a liquid. The atoms or molecules in a gas are much farther from each other than in a solid or a liquid.
Plasma: The fourth state of matter is called as plasma. Most of the matter present in this universe is found in the plasma state. All the matter that is present in the universe is made up of atoms. An atom has a nucleus which has a positive charge. All the electrons which are present orbits the nucleus. The electrons which has a negative charge are attracted by the nucleus.

Energy Fm
Introduction to energy Fm:
Modulation can be defined to as the process of varying a carrier wave which is having very high frequency with a modulating signal. The signal that needs to be modulated may be the message need to be sent to the receiver. Suppose that a message needs to be send to a longer distance, then this message cannot be send alone. This message needs to be modulated with a higher frequency carrier wave so that the message will be safe from any loss of data. I like to share this Electromagnetic Spectrum Energy with you all through my article.
Modulation is of two types; digital as well as analog. In the analog modulation there are several forms of modulations like amplitude modulation, single-sideband modulation frequency modulation etc.
Frequency Modulation
This is a process in which the frequency of modulating signal is changing. This can be defined in contrast to that of the amplitude modulation, were the amplitude gets changing. The frequency modulation is used in sending very high frequency radio waves. This also applicable in case of sending the analog TV signals.
There are two types of FMs. They are:
Wide FM
Narrow FM
Wide FM:
This type of Fm is used in order to broadcast radio signals. This is also called as W-FM or Wide-FM. In the W-FM there is no much need for very high signals.
Narrow-FM:
The type of modulation that is required for two-way radio broadcasting is known as N-FM or the narrow-FM. The narrow FM is used in order to save the bandwidth. The narrow-Fm or n-FM is capable of sending signals into the space. Please express your views of this topic Formula for Gravitational Potential Energy by commenting on blog.
Synthesizing Sound
The frequency modulation is also used widely at sound synthesizing. In the earlier synthesizers there were FM syntheses which the newer computers are done with the help of the sound cards.
The frequency modulation has got many other applications also like seismic prospecting, radars etc.

Life on Planet Earth
Introduction to life on planet earth:
After the formation of the planet earth, it could not support life, for about a quarter of age. About billion years ago, our planet condensed form a swirling cloud of inter - stellar dust and gas. The surface was too hot to allow the existence of protoplasm, the stuff of living cells. Even water, a major component of protoplasm was present only as a vapour, one among many other gases in the hot , murky atmosphere. Please express your views of this topic formula for temperature by commenting on blog.
About 3.5 million years ago life first began in water. Majority of biogenesists believe that life arose from the non-living organic matter dissolved or suspended in water. All living objects originated from non - living material. The various types of living matter we see around us did not come into being all at the same time. The earlier forms of life were very simple. Gradually, as timed passed, more complex systems came into existence. The complex organisms arose from the simpler ones. Simple plant - like organisms preceded the simple animal like organisms. Even today we can find them as fossils.
Existence of Fossils on Planet Earth
When a life form meets with death either naturally or due to natural calamities, it gets buried under the earth. The external pressures acting on the buried body, compress the body in such a way that either the body hardens or it forms an impression on the materials surrounding the buried body and the body's constituents. This hardened body of the impression of the buried body on its surrounding material is referred as a fossil. Fossils are often discovered, during excavations or when parts of the earth is overthrown during earthquakes . There are famous fossil forests covering 40 square miles in the Yellow stone region. I have recently faced lot of problem while learning Effects of Nuclear Radiation on Humans, But thank to online resources of math which helped me to learn myself easily on net.
Darwin's Hypothesis of Human Life on Planet Earth :
Darwin proposed the hypothesis of " Natural Selection" by which life may have evolved into higher forms. He said that nature selected those organisms best suited to survive in the struggle for existence. The organisms having better traits to survive than others lived longer and had more of off spring. In this way beneficial traits were passed on to longer number of descendants.
Human being constituted the pinnacle of evolution of life forms. Human beings have been on earth for some 2 million years which is less than 1 / 1000 of the time for which life existed on earth. Human beings are highly evolved species endowed with intelligence for superior to that of any other organism.
After the formation of the planet earth, it could not support life, for about a quarter of age. About billion years ago, our planet condensed form a swirling cloud of inter - stellar dust and gas. The surface was too hot to allow the existence of protoplasm, the stuff of living cells. Even water, a major component of protoplasm was present only as a vapour, one among many other gases in the hot , murky atmosphere.

About 3.5 million years ago life first began in water. Majority of biogenesists believe that life arose from the non-living organic matter dissolved or suspended in water. All living objects originated from non - living material. The various types of living matter we see around us did not come into being all at the same time. The earlier forms of life were very simple. Gradually, as timed passed, more complex systems came into existence. The complex organisms arose from the simpler ones. Simple plant - like organisms preceded the simple animal like organisms. Even today we can find them as fossils.
