boat sink because of its short side walls. The flat-bottom is also good for boating in shallow waters, they are very agile, and cheap to build. Smaller versions of these boats are called Jon boats. The bigger styles of the Jon boats are barges. The second type of vessel bottom is a round with keel design. The keel design is a narrow V-shaped hull that extends underneath to create a centerline to keep it from rolling over in rough waters. A few problems with the rounded keel hull are that it cannot
MAGNETIC SEARCH Proton precession magnetometer is used in finding objects which are buried, submerged or hidden from view. An object can be found directly where it is itself magnetic, or where it may displace material which is otherwise uniformly magnetic. In some cases an object may be found indirectly when it produces a magnetic anomaly as a consequence of it being buried or emplaced. Objects of search may involve a man-made iron or steel objects, an archaeological feature such as a brick, pottery
New? Aldous Huxley’s Brave New World illustrates a colorful, fantastic universe of sex and emotion, programming and fascism that has a powerful draw in a happy handicap. This reality pause button is called “Soma”. “Take a holiday from reality whenever you like, and come back without so much as a headache or a mythology.” ( Huxley 54 ). In his universe, Soma is the cure for everything. All problems, be they psychological, physical, or social are totally forgotten, their lurking shadows temporarily
"How much wood could a woodchuck chuck if a wood chuck could chuck wood?" An age old tongue twister that has never been answered. In this rhyme, the common assumption is that the woodchuck is a small furry groundhog like creature, but there is another kind of wood chuck that is not as common but could chuck wood. Here we will explore this path of answering this age old riddle. In the production of many wood products a common manufacturing tool known as a lathe is used, and to hold the wood in
Pendulum Investigation Plan Aim To investigate how the length of a simple pendulum will affect the time for a full swing. Variables Length The length of the pendulum has a large effect on the time for a complete swing. As the pendulum gets longer the time increases. As the pendulum gets shorter the time decreases. Air resistance A big and light pendulum bobble would be affected by a major amount of air resistance. This might cause the pendulum to move in a different way
for use in combustion engines and fuel cell electric vehicles. On a volumetric basis, the energy density of hydrogen is very low under ambient conditions. This presents greater transportation and storage hurdles than for liquid fuels. Storage systems being developed include compressed hydrogen, liquid hydrogen, and physical or chemical bonding between hydrogen and a storage material (for example, metal hydrides).The ability to create hydrogen from a variety of resources and its clean-burning
Spring Constant of Springs in Series and Parallel Planning The aim of this investigation is to examine the effect on the spring constant placing 2 identical springs in parallel and series combination has and how the resultant spring constants of the parallel and series spring sets compare to that of a lone spring with identical spring constant. Hypothesis ---------- Hooke's Law states that "The magnitude of the spring constant (k) is equal to the stretching force applied (F)
