Answer:
Traditional technologies were initially invented during the time when knowledge were still limited. So, their maximum potential were left undiscovered by the people who live in the past.
The efficiency of traditional technologies can be massively improved by adding some key features of modern inventions.
For example, Wheels has existed since 3,500 B.C. But it only reach its maximum potential in terms of speed, durability, and resistance power only after the latest latex and steel technology was invented .
Other example would be light bulbs. It was created in 1879, but only reach it maximum potential in term of energy efficiency after the invention of LED technology.
It would be A. Punic Wars
Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
Answer:
more than 4 million people
Explanation:
displaced because of conflict and hunger, including 2.2 million who have fled to neighboring countries since December 2013. Uganda hosts almost 800,000 refugees from South Sudan, down from more than 1 million in mid-2018.
