Surface Tension (N/m² = J/m³) Fluid property associated with the presence of a surface toward air Interfacial tension- is used to describe analogous phenomena for fluid having interfaces with solids or other liquids (can be +/-) Water molecules are forced toward the surface of a fluid due to placement on other molecules and attractive forces.…
Fluid: system that yield to any force that attempts to alter their shape, causing system to flow until it reaches mechanical equilibrium; fluid conforms to shape of container Molecules of liquid in condense state; maintain CONSTANT intermolecular distance. Liquid will form SURFACE. Gas will not form surface; adjust intermolecular distance to fill space provided (compression/…
Intrinsic property of particles that comprise matter Point charge: charged particle with negligible size Mass and charge are independent from each other Positive Charge (q+) and Negative Charge (q-) Coulomb’s Law Magnitude of electric force between two charged spheres is proportional to the absolute amount of charge on each sphere, and is proportional 1/r2 where…
Capacitor: two conducting plates charged with equal amount of charge of opposite signs, with insulator in between (we assume a vacuum unless said otherwise) Three quantities characterize a capacitor: 1) surface charge density 2) capacitance 3) dielectric constant Capacitance (q= C x ∆V) Unit: Farad (F) The potential difference across a parallel plate capacitor is…
Stress: force exerted per unit area of surface on an extended object. STRESS LEAD TO STRAIN Three types of deformation due to strain: Stretching (change in length) Twisting (change in angle) Compression or Expansion (change in volume) ***Each of these strains is caused by a different form of stress Tensile stress= Stretching Shearing stress= Twisting…
During adolescence, teenagers are often depicted as being vulnerable and easily influenced by their peers and by the media. As a result, the identification of societal influences on adolescents and their consequences has been studied by sociologists for many years. The use of illegal drugs is one of the behaviours that is often been studied…

Pluralists have a different view on society than the other models of democracy. Pluralists believe that people are rational and capable but often apathetic and uninformed. In democracy, pluralism consists of the compilation of many minority governments and interest groups. A single majority government of 59% is capable to pass bills and laws fairly easily. …
The twentieth century brought a radical reform of political systems in Europe, a trend of authoritarian and totalitarian regimes, with political mannerisms like the world had never seen before, was developing throughout the continent. The anti-democratic movement primarily fueled the drive for these regimes; however reasons vary from country to country. Totalitarianism involves total control…
The United Nations recognizes the impoverished state of many countries and the importance that they are given assistance. On September 8, 2000, the United Nations met with world leaders and heads of state to determine a mission or a set of goals. The United Nations compiled eight measureable Millennium Development Goals to accomplish in this…
In a fast paced and ever changing society such as today’s, it may not be clear to most the important role that history plays in the understanding of current events. However, without a good understanding of events from the past, it is hard to understand the significance that a current even possesses. This relationship can…
The works of Edgar Allan Poe are famous for featuring dark themes, violence, and psychologically unstable characters. The Tell-Tale Heart and The Black Cat are two of his best-known works, both of which involve narrators who are not of sound minds. In The Tell-Tale Heart, the narrator murders the old man he lives with because…
Almost all the information we have about Roman women derives from elite Roman males Usually women we portrayed stereotypically Chaste wives, mothers, daughters Evil seductresses, scheming power-mongers Women and Public Life Women had no political rights They could not vote They could not be elected magistrates Could exemplify an idea Embody the values of the…
Establishing shot – creates setting and constructs spatial patterns Two shot – standard Hollywood practice for a conversation Reestablishing shot – remind us where we are or return to a familiar image we’ve seen before Insert- brief shot that draws our attention to something we might have missed if a longer shot hadn’t been interrupted…
The 18th century was a tumultuous time; from revolution to innovation the world saw many changes in technology and ideals. These changes were rapid and they were feared, for good reason. The monarchs and those who had been in power for centuries that had grown comfortable believed that the past life was sufficient and thought…
There are critics who disagree with the expenditure on space exploration, which they claim can better be used to solve earthly problems. However, they seem to forget that this is one of the fields which tests a man’s intellect. But, how does a common man draw benefits of space exploration? The advances made in the…
