Answer:
The greatest gravitational potential energy is at apogee. The greatest kinetic energy is at perigee. Total Energy is constant.
Explanation:
The gravitational potential energy is at its greatest when the satellite is farthest from the earth, this point is called the apogee. And at this point the kinetic energy will be at its minimum.
The kinetic energy is greatest when the satellite is closest to the earth, this point is the perigee. And at this point the gravitational potential energy will be at a minimum level.
the total energy is the sum of the gravitational potential energy and the kinetic energy.As the satellite orbits the earth, the kinetic energy and the gravitational potential energymay be interchanged but the total energy will remain unchanged.
Answer:
The geography of ancient Greece determined and restricted its development to only certain areas, such as sea trade.
Explanation:
Ancient Greece, or rather the Hellenic city-states, are considered as one of the most developed civilizations of their time, though there can be made a solid case against it. Anyhow, in the early stages of the development of these city-states, they were very restricted in their development because of geographic factors.
The climate was of the Mediterranean type, which is a good climate, but problem was that the topography was rugged and mountainous, so agriculture was very limited to only a handful of crops and herding. Because all of the city-states had access to the sea, they focused on developing trade through it, with goods such as grapes, wine, olives, olives, and olive oil the most traded. They needed good wood for building ships, and they didn't really have any of that type. This made them heavily dependent on the Macedonians who had an abundance of wood, and considering that there was open hate between the two, it was not an ideal situation.
