Weak interaction

The 2016 United States Presidential Election has brought questions of prejudice, and how to prevent it, to the forefront of the American political and cultural discussion. One method of reducing prejudice being continually brought up in think pieces is the contact hypothesis. For many authors of these articles, the hypothesis is something of a ray of hope in what they perceive as dark times. Per James Hamblin (2016) of The Atlantic, application of the hypothesis can be a tool to “immunize” a…

Purpose Titration is a technique where an unknown solution’s concentration is determined with a solution of a known concentration. In this case, the known solution, NaOH, is dripped into the unknown, unknown #2, with a burette. The NaOH is dripped until the reaction is complete, while measuring the pH per amount of base added. Using the data collected, the equivalence point can be found and the concentration can be calculated. Then the KA can be found at specific points (20%, 40%, etc). After…

Paramecia, unicellular cilliated protozoa, usually are ovoid and elongated. They widespread in brackish environments and freshwater. Length of the species are various ranging from 50 micrometers to 330 micrometers. They feed on yeasts, algae, and small protozoa which are captured by them through phagocytosis, devouring a particle by “wrapping pseudopodia around it and packaging it within a food vacuole” (Campbell and Reece 2011). They also serve as the models for the study of basic biological…

categories: they can be strong or weak. Strong acids completely dissociate their H+ and weak acids only partially dissociate their H+.3 This means that a strong acid cannot return to its initial state once it undergoes a reaction. On the other hand, a weak acid can return to its initial state. Bases are cations that have a hydroxide anion added into their molecular formulas. Bronsted defined bases as a proton acceptor.3 Just like acids, bases can be either strong or weak. Strong bases…

acid. If the solution is closer to zero it makes it a stronger acid, but if the solution is closer to seven than it is a weak acid. If a solution has a pH of seven then it is neutral. A pH of eight to fourteen indicates that the solution is a base. The farther the pH level is from seven the stronger the base. If the solution has a pH close to seven that indicates that it is a weak base. To determine the pH of certain substances one will use an indicator. An indicator is a dye…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

Swipe bloodstains which is in the catorgory of transfer bloodstain patterns, are created when a wet bloody object comes in contact with a target surface. Its use to identify an object or body part. A wipe pattene is created from an obkect moving through the a bloodstain, while a swipe pattens is created from an obect leaving bloosstain. Number is mark a swipe bloosstain becasue there seems to be a swipe of a hand print or sometime of object that has moved through the bloodstain, their are also…

1) According to the article, “Theories and Practices of Multimodal Education: The Instructional Dynamics of Picture Books and Primary Classrooms,” multimodality is defined as a product that includes multiple modes of representation. These modes represent elements of print, visual images, audio, and design. In other words, the term “text” is no longer paper and pencil to make print, but can be a combination of many other modes as well. This new way of thinking about text and what it entails puts…

Ever After, directed by Andy Tennant, scrutinizes the expedition of Danielle de Barbarac, a young girl living in 16th-century Europe. Danielle’s lifetime is a fresh, natural retelling of the standard fairy tale of Cinderella. First, a devoted father's princess, she is now obligated to be a servant for her stepmother and stepsisters after the death of her beloved father. She is a lady who has sympathy and compassion for the people of France and desires a world that is consolidated and not divided…

Computers, which have been around from less than a century, have made a huge impact around the world. However, even if we realize that computers are a basic tool in everyday life, people underestimate the capacity of these computing devices. The first time Google announced that their AlphaGO was going to compete with Go master Lee SeDol Kudan, my comrades and I had a strong faith on Lee. However, as we all know, the result surprised the world. Consequently, I believe we should not only make…
