Low-Earth Orbits may be defined as ones within a locus extending from the Earth’s surface up to an altitude of 1,200 miles. It is this orbit in which the atmosphere drag is minimal, if not totally absent. The Low-Earth Orbit finds varied use in space technology. This orbit is used to visit the International Space Station or the Space Shuttle to perform experiments, installations and repair of astronomical equipments (Iowa State University, 2016). Satellites are a vital part of this orbit. They are required for varied purposes such as communication, weather, GPS, space travel etc. A satellite ...

Question #8

Angular momentum refers to the resistance of a rotating body to change its spin rate or direction of spin. Angular momentum can be determined by the product of the moment of inertia and the angular velocity, or by the cross product of the moment arm and the product of the mass and velocity vector of the body (Sellers 2004, 112-113). For this particular problem, we will use the latter to determine the angular momentum. H=R×mV H=0.5 m×0.25 kg2 ms H=0.25 kg∙m2s Since angular momentum is conserved, the angular momentum of the system every point in time ...

Issue Summary:

The population issue that I presented was the Heart disease. This refers to the class of diseases which entail the blood vessels, the heart or a combination of such. This is any of the disorder or disease relating to the cardiovascular system, mainly cardiac disease as well as the vascular disease of kidney and brain. This also involves the disease which affects the peripheral arteries. The heart disease is mainly caused by hypertension and atherosclerosis or a combination of both. Aging is also associated with morphological and physiological changes which alters the functioning of the cardiovascular system. This will therefore lead ...
