An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
In 30 seconds, an electric device with a current of 15.0 A would allow approximately 2.81 billion billion electrons to flow through it. This is calculated using the relationship between current, charge, and the charge of an electron. The final calculation shows that the total charge moved is 450 coulombs, leading to this number of electrons.

To analyze the paragraph in functional terms, we look at each sentence to determine its role within the paragraph. Here’s a breakdown of each sentence:
Sentence 1: “Terrorism is caused by a number of factors.”
This is the topic sentence . It introduces the main idea of the paragraph, which is about the various causes of terrorism.
Sentence 2: “The first is the desire of a population to break away from a ruling power and create a state of its own.”
This is a major supporting sentence . It gives a specific cause of terrorism, supporting the topic sentence.
Sentence 3: “In the 20th century, this was seen often times with regions or states attempting to gain independence from their colonial masters.”
This sentence provides specific examples as major support to illustrate the first cause.
Sentence 4: “However, as Bruce Hoffman notes, ethno-nationalist terrorism had been around decades before even the First World War.”
This is a secondary supporting sentence , adding historical context and authority to the previous examples by referencing a respected source.
Sentence 5: “Perhaps the most notable of these groups, formed before and after WWII and inspired by the weakening of imperial powers, was the Jewish Irgun Avai Le'umi who fought British rule in Palestine so as to attain the creation of a Jewish state.”
This acts as a specific example providing a detailed instance of the first cause mentioned.
Sentence 6: “Another cause of terrorism is discrimination.”
This introduces a second major supporting point about the causes of terrorism.
Sentence 7: “Many times when groups face discrimination in the countries they reside, it causes them to be isolated.”
This sentence explains the impact of discrimination, supporting the second major point.
Sentence 8: “Such isolation in the process causes them to be bitter, resentful and vengeful.”
This provides further support and explanation of how discrimination can lead to terrorism.
Sentence 9: “What about the role of religion? That religion has resulted in the creation of violent groups that are self-seeking cannot be disputed.”
This introduces the third major supporting point or cause, which is the role of religion in terrorism.
Sentence 10: “Terrorism gives rise to violence and threats in the achievement of political ambitions globally.”
This is the concluding sentence , summarizing the main idea about the effect of terrorism on a global scale.
Overall, the paragraph uses a structured approach with a clear topic sentence, followed by points and supporting evidence, and ends with a conclusion.
