C. Heat
When heat is added to a substance, the molecules and atoms in that substance vibrate faster and move farther apart, and when a substance is cooled, the molecules vibrate slower and move closer together.
For example, as ice is warmed, the energy from the heat causes the molecules of water to move faster and farther apart, causing it to melt and liquify.
Answer:
The Roman Senate was the main deliberative body of Ancient Rome. Its members represented the two most important political groups of the time, the Optimates (aristocrats) and the Populars (the people). It had various functions, the most important being to control the foreign policy and finances of the Roman nation. Initially, the Roman Senate was made up of 300 members, although later this number rose to 900 senators.
Instead, the Athenian Assembly, called Ekklesia, was the deliberative body of Athenian democracy, in which all free men of a certain purchasing power gathered to make the main decisions of the polis. Because there was no limit on the number of free men, these assemblies did not have a certain number of members, which used to far exceed thousands of people.
In April 1994 in Rwanda (East Africa) began the genocide of Tutsi - an ethnic minority, which for centuries dominated the Rwandan majority - Hutu. During the 100 days of incredible violence, about 800 000 Tutsi and moderate Hutu were murdered. The international community, unfortunately, didn't respond to this event on time. The conflict was considered as an internal case and the Security Council of the UN didn't decide to intervene. Even though the scale and character of the conflict was well known the United States didn't want to get involved because of a painful experience from its intervention in Somalia in 1993 (the story was presented in the movie Black Hawk Down).
The UN troops arrived in Rwanda when the major fights were over. They assisted only by the burial of deaths and protected the survivors. Today we know that other countries (for example France and China) were selling arms to the Rwandan government.
What could be the response? The international community could prevent the growing hostility and animosity between Hutu and Tutsi already before the genocide. They should have introduced an embargo on arms in order to prevent the escalation of violence. When the conflict had begun, a military intervention should have taken place.
Hello. This question is incomplete because you forgot to show the graph that is part of the question and that is necessary for it to be answered.
The chart is attached below.
Answer:
Watertown, Massachusettes
Explanation:
To answer this question you just need to read the information shown in the graphics. This way:
The blue dots within the graph represent the concentration of particulate material in the air during 1990-1998. Among these points, the one that represents the city of Watertown, Massachusettes is the one that represents the lowest concentration of these particles, which justifies the low number of relative mortality in that city in that same period.
