After turning on the power supply, the current was adjusted to 5 different levels using the voltage knob, and the magnetic field at each current level is recorded. However, the voltage knob was turned to the left thoroughly, immediately after each current level to prevent the sensor from overheating. Since the data taken for the magnetic field was in Gauss, we converted to the Tesla. At last, we calculated the magnetic field and the percent errors of calculated and measured magnetic field using the equations. Part II: Magnetic Force
Valerie Beketova Dr. Bennett AP Environmental Science 10 December 2015 Chapter 14 Outline Earth is a very dynamic planet Earth is made up of different layers: - Core - interior made up of dense, extremely hot metal, mostly iron. It is the most inside layer of earth. - Mantle - hot, pliable layer that surrounds the most inner layer, the core. It is less dense than core.
(Androulidakis. 2012). There are different solutions to isolate a mobile phone from electro-magnetic radiation, and probably the best one is the use of a cage called “Faraday Cage”. The use of this solution is recommended not only because the isolation from external
a. Water boils to produce steam at 100 C (212 F) b. Water produces gas with sodium metal c. Water and oil separate when combined d. Water dissolves sugar 22. In the experiment, students put brine shrimp in water with different concentration of salt and counted the number. Which of the following changes to the experiment will increase confidence in the validity of the result? a. Count the number of dead brine shrimp instead of living brine shrimp b. Add more brine shrimp to the water with the highest salt concentration c.
Book: If you give a mouse a cookie by Laura Numeroff, Harper Collins Publisher Summary: In the beginning of the book a mouse asked a boy for a cookie which lead for a glass of milk and more request. Its all began with a mouse asking for a cookie which made the mouse want something new, afterward the mouse creates an endless stream of request that eventually will turn into a cycle. Which leads the reader thinking the cycle will go on all over again beginning with the mouse asking the boy for another cookie. The philosophical context is determinism because it is like life is already set for them with repeated steps for the near future.
The Carrington Event, also known as the Solar Storm of 1859, is the largest geomagnetic solar storm in recorded history, resulting from a coronal mass ejection; a massive surge of magnetized plasma originating from the Sun’s surface on the morning of September 1st, 1859. As the mass of plasma hit the Earth’s magnetosphere mere hours after the event had occurred on the Sun’s surface, southern aurorae were seen as far north as Queensland, Australia, and the aurora borealis was powerful enough that residents of the north-eastern US could read a newspaper by the aurora’s light. The solar storm ravaged the primitive telegraph communication system used in 1859, and caused damage to electrical grids worldwide. CAUSES The Carrington Event was caused by a massive burst of electromagnetic radiation, magnetized gas and plasma released into the solar wind by the Sun’s corona in a phenomenon called a coronal mass ejection (CME).
The inner core is too hot to hold a permanent magnetic field and is slowly becoming thicker as more of the outer core solidifies slowly over time due to the gradual cooling of the Earth. Chemical Divisions of the Earth's Layers The Earth's layers are also classified chemically as the Crust, Mantle, Outer Core, and Inner Core.
In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung.
Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
The invention that I researched is the magnet, the central idea is that the magnet was very important for toy makers and scientists. The magnet is important because when a toy maker makes a handheld game they use magnets to keep certain things together like circuits. As a matter of fact if the magnet wasn’t invented/found then we wouldn’t have many of our favorite technology things like phones, tablets, televisions, and computers. The magnet was not invented it was found by a ancient greek man named Magnes. He was walking around when all of a sudden his shoe which had nails in it suddenly suck to a odd rock, he had discovered the magnet!
On earth, high-energy particles carried by solar winds rarely reach the surface of the earth and its atmosphere. In the article, [2] the author argues that it is impossible for almost all high-energy particles to reach the Earth's surface due to protection by the Earth's magnetic field. Outside of earth, however, space weather created by the sun has a significant impact on the solar system and other planets, comets, asteroid and space itself. Significantly, space weather can have serious negative effects on an astronaut's health and their spatial equipment. Astronauts, their tools and vehicles such as the space shuttle must deal with high-energy particles, ultraviolet radiation, and solar
Without him being able to assume basic knowledge of physics, in particular the electromagnetic forces active in magnets, Feynman cannot accurately describe what is occurring between those two hunks of iron without raising far more questions than he will serve to answer. This is because he could only use a metaphor or simile to describe the interaction to a layman. His example is a rubber band acting like the force pulling the two magnets together, but then why does the rubber band contract? What do you know, we are right back at the
Hughes would tell you to experiment and discover the answer yourself.
This experiment has to be carried out carefully
