Answer:
time taken for 25% Phlebotinum and 75% Dilithium is 168 million years
Explanation:
radioactive isotope of Phlebotinum decays into Dilithium.
time taken to half life takes = 42 million years
half life means that the Phlebotinum is 50% and Dilithium is also 50%
and now it is given that Phlebotinum is 25% and Dilithium is 75%
hence this condition will come after two half lives.
for one half life it takes 42 million years
and for second half life time becomes 4 times of first half life
time for 25% Phlebotinum and 75% Dilithium is = 4 × 42
= 168 million years.
hence time taken for 25% Phlebotinum and 75% Dilithium is 168 million years
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.
<span>Guyots are seamounts that have built above sea level. Erosion by waves destroyed the top of the seamount resulting in a flattened shape. Due to the movement of the ocean floor away from oceanic ridges, the sea floor gradually sinks and the flattened guyots are submerged to become undersea flat-topped peaks.</span>
