Abstract:
The change in weight induced by a magnetic field for three solutions of
complexes was recorded. The change in weight of a calibrating solution of 29.97%
(W/W) of NiCl2 was recorded to calculate the apparatus constant as 5.7538. cv
and cm for each solution was determined in order to calculate the number of
unpaired electrons for each paramagnetic complex. Fe(NH4)2(SO4)2€6(H20) had 4
unpaired electrons, KMnO4 had zero unpaired electrons, and K3[Fe(CN)6] had 1
unpaired electron. The apparent 1 unpaired electron in K3[Fe(CN)6] when there
should be five according to atomic orbital calculations arises from a strong
ligand field produced by CN-.
Introduction:
The magnetic susceptibility is a phenomena that arises when a magnetic
moment is induced in an object. This magnetic moment is induced by the presence
of an external magnetic field. This induced magnetic moment translates to a
change in the weight of the object when placed in the presence of an external
magnetic field. This induced moment may have two orientations: parallel to the
external magnetic field of or perpendicular to the external magnetic field. The
former is known as paramagnetism and the later is known as diamagnetism. The
physical effect of paramagnetism is an attraction to the source of magnetism
(increase in weight when measured by a Guoy balance) and the physical effect of
diamagnetism is a repulsion from the source of magnetic field (decrease in
weight when measured by a Guoy balance).
The observed magnetic moment is derived by the change in weight. This
observed magnetic moment arises from a combination of the orbital and spin
moments of the electrons in the sample with the spin component being the most
important source of the magnetic moment. This magnetic moment is caused by the
spinning of an electron around an axis acting like a tiny magnet. This spinning
of the ³magnet² results in the magnetic moment.
Paramagnetism results from the permanent magnetic moment of the atom.
These permanent magnetic moments arise from the presence of unpaired electrons.
These unpaired electrons result in unequal number of electrons in the two
possible spin states (+1/2. -1/2). When in the absence of an external magnetic
field, these spins tend to orient themselves randomly accordingly to statistics.
When they are placed in the presence of an external magnetic field, the moments
tend to align in directions anti parallel and parallel to the magnetic field.
According to statistics, more electrons will occupy the lower energy state then
the higher energy state. In the presence of a magnetic field, the lower energy
state is the state when the magnetic moments are aligned parallel to the
In the twentieth century the medical field has seen many changes. One way that hospitals and nursing specifically has changed and implemented the changes is by pursuing accreditations, awards, and recognitions. The purpose of this paper is to understand Magnet Status and the change required by hospitals to achieve it.
The Time Machine by H. G. Wells was an intriguing and exciting book about a Time Traveller and his journey’s through time. In this book, the Traveller explained to a group of men who were discussing the nature of time that time was the fourth dimension; just like the three dimensions of space: length, width and height. The Traveller argued that since time was a dimension, then it stood to reason that people should be able to move along the time continuum, into the past or the future. Most of the men do not seem to believe the Traveller or his theory, but agreed that they would like to travel in time, and talked about what they would do if they could. To illustrate his point, the Time Traveller went and got a model of his time machine from his laboratory to demonstrate and later returned to detail the places, things and people he had seen in his travels with his working Time Machine. Throughout the story, the Time Traveller faced setbacks and challenges, but the book outlined how he persevered and pointed to the future mankind faced.
For hospitals to reach their peak in the healthcare world they must work to achieve a prestigious credential by the American Nurse's Credentialing Center ( Truth about nursing). In order to receive such a credential, hospitals must fulfill a set of criteria that will take a lot of work and reform within the hospital itself. To receive magnet status hospitals have to express the fourteen forces of magnetism along with the strict list of requirements (Flores, 2007). Magnet status along with everything has its benefits along with its problems. This credential has been researched in depth, and some research feels that certain thing should be changed in order for magnet hospitals to be the best they can possible be. Lastly, there is no doubt that magnet status is of great value because of how it transforms hospitals from great to greater.
The Magnet Recognition Program was initially developed to attract and maintain nursing staff. According to American Nurses Credentialing Center’s (ANCC) web site, the program “was developed by the ANCC to recognize health care organizations that provide nursing excellence. The program also provides a vehicle for disseminating successful nursing practices and strategies.” Nursing administration continues to have an integral role associated with the demonstration of excellence in achieving the highest honor of nursing distinction. The exploration of force one, quality of nursing leadership, continues to be the foundation of magnet recognition.
I am going to carry out an experiment to measure the change in mass of
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
Octavia Butler’s novel, Kindred, is categorized as science fiction because of the existence of time travel. This novel correlates with Gunn’s definition because it connects with the fact that Dana, a 26-year old-American woman, travels from the future where she lives in California, to the past in Maryland. She traveled from the year of 1976 to the year of 1815. Some may think that time travel is impossible, but the article, Time Travel and Changing the Past: (Or How to Kill Yourself and Live to Tell the Tale) written by G.C Goddu says otherwise. He states, “not only is time travel possible, but so is changing the world” (Goddu 17). He also uses a model to explain why he think that time travel is possible. He uses some examples to prove this. His first example, Paul at 32-years old, leaves from February 12, 1998, for the past and touches base on January 28, 1972. On this outing, in an attack of self-skepticism, he finds and murders his 3-year-old
The Effect of the Number of Coils on an Electromagnet On Its Strength Aim: - To establish whether a variation in the number of coils will affect an electromagnet's strength. Scientific Knowledge -. The concept of electromagnets is fairly simple. An iron nail wrapped in a series of coils of insulated wire and then connected to a battery, will enable the nail to pick up paper clips. This is because the current emitted from the battery to the coils magnetizes the nail to the surface.
I found out that the iron rod picked up many nails when turned on and
To the dismay of some and a necessity for others, scales can be found about everywhere in today’s society. It never fails; if you go to the doctor you will step on the scale. They are at the grocery store, in most bathrooms and even in some of our favorite stores. Were we might even pay a quarter to have a machine tell us our weight, out loud. We as a society are obsessed with our weight. You’re asked for your weight when renewing your driver’s license. Every time you get in an elevator and see the little sign saying do not exceed *** lbs, the quarter-pounder with cheese and milkshake you ate for lunch, is brought back to your memory. A scale receives more mental and physical abuse than any other appliance that has ever been invented. All this abuse stems from a lesson each of use were taught at a young age, which is that we should always tell the truth. Well let’s look a little deeper into the scale and see the physics involved in how two different types’ of scales weigh objects.
The hanger with appropriate amount of slotted mass was put on the tile. The sand is a sand. Use the balance to measure the total mass m. 4. What is the difference between a.. Sufficient length of string was attached to the hanger so that the free end wraps around the axle of the flywheel.
The second law is, “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” The heavier object requires more force to move an object, the same distance as light object. The equation gives us an exact relationship between Force, mass, and acceleration.
We Like It, We Love It, We Want Some More of It: The Allure of Time Travel
Overall, Grey’s two arguments for no destination relied too much on the concept on presentism, which allowed space for rejections and solutions. The solutions and arguments against his paradox were all reasonable and sound proposals, which still allows the concept of time travelling to be possible.
