Mechanism Description
Lightning is a natural electric force that I chose. The cause of lightning requires to types of charges negative and positive. A storm cloud is divided into two parts top being being positive and the bottom being negative. The reason for lighting to happen is because of this thing called charge separation which one positive charge and one negative charge split in half. Up to millions of water droplets are contained in one storm cloud. Water from the ground evaporates, and rises from the ground and goes up to the cloud rises up and comes together as it goes up to the cloud. The clouds collides with the moisture and then go up into the cloud. When they hit, the electrons get taken off the droplets, making the negative electrons turn into a positive electron. The moisture will always look for cold temperatures at a higher altitude. At a cold temperature the water will freeze. The particles then come together and form a region that’s inside the water. The frozen portion of the water of moisture becomes negatively charged and the outer droplets which gives it a more positive charge. The currents inside the cloud rip the protons off the droplets and move them inside the cloud and goes to the positive side. The frozen particles which contain the negative charges are then moved to the bottom half. Making the clouds polarized. The mechanism is what causes the polarization of the storm clouds. A storm cloud becomes polarized when one positive charge moved to the top of the clouds and one negative charges moving towards the bottom of the cloud.

...ve a constant voltage because when you put a load on them, the voltage doesn’t change. There are two types of Van de Graaff generators but for now I will just focus on one. One that uses belts and rollers for charging and at the top there is a sphere where the electricity circulates.
What is the energy source/how is it transformed into electric energy?
The motor is turned on, the lower part begins turning its belt. The belt is made of rubber so it attracts more electricity than a regular belt would. The lower part builds to have a negative charge and the belt makes a positive charge. The reason this happens is because in the belt there is a silicon part that is built in the belt making it more negative than rubber, the lower part is taking electrons from the belt as it goes over the roller. Causing the electricity to go up into the sphere and flowing through it.
2. Now the belt is turning. This makes the secondary clutch turn, which causes the track to turn and the snowmachine to move forward.
Isaac’s Storm, by Erik Larson was a very fascinating book because it is difficult to say absolutely what the true subject of the book is. There are three key players in the book, first it is Isaac Cline a meteorologist for the U.S Weather Bureau, The U.S. Weather Bureau itself, and finally the storm of 1900. However, all three elements collaborate with one another in a significant way. The storm of 1900 is the main catalyst for one of the most devastating storms in the United States. However, the Weather Bureau and Isaac Cline both had an impact on the outcome of the catastrophic storm. The book generally focuses on the Galveston Hurricane of 1990, but more so the actions that Isaac Cline takes, or didn’t take rather. It was very tricky to
The technique of imagery is the strongest technique Bradbury uses in his text, “ The sounds of Thunder”. Here we can see images in our head what is happening, and we can also smell it. We can smell what he is talking about because we all have probably smelled something nasty before and when we read the text, it reminded us of that scent. It is very important for authors to add imagery because it helps the reader imagine what is happening, therefore, he or she put themselves in the characters shoes and that gives them a better sense of the
Tornadoes form from wind shears. Wind shears form from warm air that is found at ground level; when it’s raised, the updraft meets a down draft of cooler air that is moved in the opposite direction of the warm air. When both are pushed towards the Earth, this creates wind shear. A spinning tube of air, created from wind shear; tilts upward into a vertical position, as the updraft sucks up moisture from the ground and into the sky. As the warm air cools high in the sky; this produces condensation. The condensation then produces thunderclouds, which rise to 30,000+ feet. The spinning formations of air are then trapped and lifted into the thundercloud. This begins as swirling motion and as continued (if the winds remained viable), a supercell will form. Mesocyclones as they are known are a rotating cloud. If these rotating clouds run into humid air it will spi...
As evening approached, several thunderstorms began to take on the characteristics of a supercell thunderstorm. Supercells, which are intense, broadly rotating thunderstorms, are the most v...
...late 17th century, and beginning of the 18th century, transportation was favored by American society so much, the wealthier would hire chauffer’s to take people places. So not only did the motor produce a better and more efficient life style, it also created a huge business industry, as we know it today called, “valeting”. The actual motor worked like this. “Two cups filled with mercury would contain a magnet and a wire with one being fixed and the other free to move. Whenever a current was passed through the wire, the free moving magnet or wire would revolve around its fixed partner due to the electromagnet forces being produced.” (History of Innovation). This first motor was a prime example of the fact that movement could be created by electricity and electricity could be created by friction. This motor was the most useful and applicable invention in the 1800’s.
A study was done to understand the effects of thundersnow within lake effect snow events which took place between 1995 through 2007. What the study observed was that the majority of cloud to ground lightning occurred in lake effect storms during the late fall and early winter months. Twenty-seven percent of storms however occurred between the January through March period. BUFKIT was used in this study to determine the environment that would be required for lightning to occur in these storms. “The presence of the layer from -10 to -25 C within the predicted lake-effect cloud layer (lake-induced LCL to EL analyzed within BUFKIT) appears to be necessary, but not sufficient, condition for CG lightning to occur; values over 500 J/kg of lake induced CAPE much also be present for CG lightning initiation.”
Kate Chopin’s “The Storm”, is a story filled with metaphorical references between a thunderstorm of rain and a thunderstorm of passion. Calixta, Bobinot, and Bibi led, what one would assume to be, a rather normal life. While Bobinot and Bibi are in town shopping they notice a storm approaching, and “Bobinot, who was accustomed to converse on terms of perfect equality with his little son, called the child’s attention to certain sombre clouds that were rolling with sinister intention from the west, accompanied by a sullen, threatening roar.” However, a moment a Mother Nature’s fury unleashed a wealth of passion between Calixta and her former beau Alcee Laballiere.
...was attached to the disk as well as the galvanometer. As the crank was rotated, Faraday noticed that the needle on the galvanometer moved. Moreover, the needle remained in that condition when the crank was rotated at a constant speed. This device Faraday named the Electric Dynamo (Williams).
A direct current in a set of windings creates a polar magnetic field. A torque acts on the rotor due to its relation to the external magnetic field. Just as the magnetic field of the rotor becomes fully aligned with the external magnetic field, the direction of the current in the windings on the armature reverses, thereby reversing the polarity of the rotor's electromagnetic field. A torque is once again exerted on the rotor, and it continues spinning.
The basic trimmer works by the engine driving a multi-bearing supported hardened steel shaft housed in an aluminium tube through a centrifugal clutch this shaft is connected to a “head” that holds a nylon line that spun at high revolutions per minute (RPM). This nylon line then cuts the grass by hitting the blades of grass at high speed, this cause the grass to be severed at the point of impact. Thus trimming the grass.
Have you ever seen a levitating orb? A real orb just floating in the air. This is not some magic trick, it is science. To make the orb levitate you must first know about electricity and how it works. Static electricity is what causes it to levitate.
To understand how this motor works, we must understand the relationship between electricity, and magnetism or simply put electromagnetism. Direct electric current in a simple description: There are two requirements for current flow. The first is a source of electrical potential energy or EMF (electro motive force,). The second is a conductor that provides a complete loop to carry the current. The reason a conductor will conduct is found on the atomic level. A conductive atom’s valance shell is not completely full electrons will flow from atom to atom because of this. When these electrons move from one atom to another that is electrical current (a brief description that is).
An electric charge on an object that causes the object to attract or repel other objects is called static electricity. The adjective static describes something that does not move. Charges on an object are called static electricity to contrast then with the moving charges in an electric current.
In 1910, Arthur Eddington, a British Astrophysicist, discovered solar winds. Solar winds are basically a continuous flow (they are never ending basically) of particles from the sun. They are also known as stellar winds. Their usual way out of the sun is the coronal holes. Their main cause is an expansion of gases in the corona, which is the outer layer of the sun. The idea that the corona is plasma was thought of by Richard C. Carrington. The temperature of the corona is 2,200,000 degrees Celsius. It is so hot that not even the sun’s gravity can contain it. It heats gases and makes them expand. The gas items run into each other as they are heated. As a result, they lose their electrons. Then, the atoms become ions with a positive charge, the electrons and ions (which are mostly Hydrogen ions) make up the solar wind. The velocity of solar winds goes from 250 to 1000 kilometers every second. It has a density of 82 ions for every cubic inch, or 5 ions per cubic centimeter. Solar winds are the cause of many occurrences in the solar system like Mercury having no atmosphere, and Venus’ acidic, radiation filled clouds. They are also known as electrically charged hurricanes.
