Charge Definition and Examples (Physics and Chemistry)

In the context of chemistry and physics, charge usually refers to electric charge, which is a conserved property of certain subatomic particles that determines their electromagnetic interaction. Charge is a physical property that causes matter to experience a force within an electromagnetic field. Electric charges may be positive or negative in nature. If no net electric charge is present, the matter is considered to be neutral or uncharged. Like charges (e.g., two positive charges or two negative charges) repel each other. Dissimilar charges (positive and negative) attract each other. In physics, the term charge may also refer to color charge in the field of quantum chromodynamics. In general, charge refers to a generator of continuous symmetry in a system. Charge Examples in Science By convention, electrons have a charge of -1 while protons have a charge of 1. Another way of indicating charge is for an electron to have a charge of e and a proton to have a charge of e.Quarks possess what is known as color charge.Quarks may possess flavor charges, including charm and strangeness.Although hypothetical, magnetic charge has been postulated for electromagnetism. Units of Electric Charge The proper unit for electric charge is discipline-dependent. In chemistry, a capital letter Q is used to indicate charge in equations, with the elementary charge of an electron (e) as a common unit. The SI derived unit of charge is the coulomb (C). Electrical engineering often uses the unit ampere-hour (Ah) for charge.

The Long Term And Short Term Memory - 1926 Words

According to philosopher-psychologist William James, memory is a generalized concept that encompasses the long term and short term memory. Kendra Cherry, psychologist expert, defines long term memory as â€Å"storage of information over an extended period.† (Cherry n.d.) An individual’s long term memory is structured by a semi-permanent chemical and the anatomical hippocampus. The hippocampus is in the center of both hemispheres of the brain and works in accordance with the amygdala to allow information to be imported to form memories. In relation to her research of the long term memory, Cherry also provided information on the characterization of the short memory which is described as, the â€Å"primary or active memory† that presently takes in information. (Cherry n.d.) The thalamus is a large portion of a dual lobed mass of matter that is located under the cerebral cortex. An individual’s brain goes through three stages of the retention of information wh ich are: encoding, storage, and retrieval. Our brain codes information in three methods which is through visual, acoustic, and semantic simulation. Encoding means that certain signals are sent to the brain. Storage means that the brain is maintaining information over time. Information is received through the working memory that consist of auditory memory and spatial memory. (Morrin, n.d) Spatial memory captures the visual aspects of the information being presented to the subject.

Material culture is just what it sounds like: ‘food, furniture, building and other group of things. ’ Central to a group’s material culture is its technology (Weber, 2000). When this material culture changes, the non-material cultures, which includes norm, value, beliefs, practice, mores and folkway must change in response change in response.Adaptive culture comprises the portion of nonmaterial culture that adjusts to material conditions. It always takes a while for the adaptations to catch up with material changes, and this gap is the â€Å"cultural lag† (Ogburn, 1957).
