early years Tsiolkovsky caught scarlet fever and became 80% deaf. Together, the
theoretical wor ...

A Discussion On Earthquakes
Number of Words: 1189 / Number of Pages: 5
... contemplating how earthquakes might possibly be prevented, it is
essential that the process and formation of and earthquake be understood.
Earthquakes are caused when the earth's crustal plates move, rub, or push
against each other. The earth's crust (the outer layer of the earth) is made up
of seven major plates and approximately thirteen smaller ones. The name plate
is used to describe these portions of the earth's crust because they are
literally “plates” or sections, composed of dirt and rock. These plates float
on molten lava, called magma. Since the plates are floating on ma ...

Incubation can take from 150 days to seven or more months. The female
may produce any where from 20,000 to 100,000 eggs over a period of several days.
During incubation the female octopus will take to cleaning and aerating the eggs.
This takes place at a depth of less than 50 meters

... energy,
and some more neutrons.
This process continues causing a chain reaction withut any outside assistance,
and the Uranium has "gone critical"(Martindale, 794-195). This chain reaction
is the basis for how nuclear power is made.
The amount of the energy that is given off in nuclear fission is astronomical.
To equal the amount of energy given off when splitting some uranium the size of
a golf ball, one would have to burn approximately twenty-five train cars full of
coal. Presently, the planet contains twenty-five times more nuclear fuel
compared to fossil fuel. On average, an atomic power pla ...

... possible
displacement
w is the angular frequency and f is the phase constant
or phase angle and has units of radians per second.
The phase constant determines the position of the particle at time t = 0. The quantity (wt+ f) is called the phase. The above function x repeats itself whenever wt = n2p where n is an integer. The period T of the motion is the time it takes for the motion to complete one revolution or cycle. The unit for the period T is seconds. Since the function repeats itself every period T for any time t and it has already been written that we know that wt = 2p when the fun ...

Air Pollution

... from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb sunlight which reduces visibility. Particles also reduce visibility by attenuating the light from objects and illuminating the air causing the contrast between the objects and their backgrounds to reduce. Not only does it effect visibility, but it hastens the erosion of building materials and the corrosion of metals, interferes with the human respiratory system, and brings toxic materials into the body. The small particles cause chronic bronchitis, bronchial asthma, emphysema and lung cancer (Hodges ...

Global Warming
Number of Words: 845 / Number of Pages: 4
... But, problems may happen when the amount of
greenhouse gases increases.
Since the beginning of the industrial revolution, great amounts of carbon dioxide have increased nearly 30%, methane concentrations have almost doubled, and nitrous oxide concentrations have risen about 15%. These increases have made the heat-trapping worse in the earth's atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space, but, sulfates do not live long in the atmosphere.
Why are greenhouse gas concentrations increasing? Most scientists believe that th ...

... with resident wild and hive populations of European honeybees. However, many of the basic African honeybee traits remain, including rapid population growth, frequent swarming, minimal hoarding of honey, the ability to survive on sparse supplies of pollen and nectar, and a highly defensive nature.
Africanized honeybees are more difficult to manage than European honeybees and produce less honey. The businesses of many beekeepers in Latin American countries have failed as a result of Africanization of the native hives. Africanized honey bees are not expected to have the same impact in the United State ...
