B And C Opposite Side
920 wordsTrigonometry is based on the study of right-angled triangles. This is a form of geometry that developed out of the study of the stars. It is also concerned with the relationships that exist between the sides and angles of triangles, and their measurement. Trigonometry comes in two forms, spherical and plane. Spherical is the study of curved triangles lying on the surface of a hypothetical sphere, which is mainly used by astronomers and navigators. Plane is the study of more variety and is mainly...

People use one of two routes when evaluating messages in the public service announcements, the central and peripheral. The second reason is fear appeals tend to be less effective when used in short televised public announcements. They are more appropriate for formats that allow more elaborate and longer messages to reinforce self-efficacy. The third and final reason is co...

Cross Sectional R R
864 wordsDetermination of r for a Metallic Conductor To determine the resistivity (r) of a given sample of wire Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R = Voltage / Current Resistance of a co...

1,938 wordsThe Rise of Einsteinian Special Relativity In 1905, Einsteins Theory of Special Relativity was proposed. The reason that it is so special is because it was part of the more complex and extensive Theory of General Relativity, which was published in 1915. His theory reshaped the world of physics when it contradicted all previous laws of motion erected by Galileo and Newton. By mathematically manipulating these previous laws of motion, physicists in the nineteenth century were able to explain such ...

Focal Length Distant Objects
1,280 wordsLight and other kinds of electromagnetic radiation coming from the universe outside the Earth must travel enormous distances through space and time to reach observers. Only the brightest and nearest stars can be seen with the unaided eye. To see farther and to clarify and measure what is seen, a telescope is needed. The word telescope is derived from the Greek words tele, "from afar, " and shops, "viewer. " Even a simple homemade telescope can clearly show Saturn's rings, Jupiter's bands and red...

Carbon Dioxide Surface Area
3,396 wordsOne of the most little known species of ants in North America is the leaf-cutter ant. This is mainly because it lives in tropical environments and it is not aggressive to animals or humans if not disturbed. The leaf cutting ant is a social insect. Alone the ant is virtually helpless but with the colony it can be a thing feared by animal and human alike. The leaf-cutting ants have a very important role in the tropical forest. They create and manipulate the environment around them. They also can d...

Inversely Proportional Cross Sectional
1,082 wordsAim I am going to be studying the resistance of wire. The purpose of this investigation is to see how length and thickness of wire affect the dependent variable, resistance. Prediction I predict that, as the length of the wire doubles, the resistance will also double, but as the cross-sectional area of the wire doubles, the resistance halves. This means that the length will affect the resistance more than the thickness will. Hypothesis Resistance is caused by electrons bumping into ions. If the ...
