An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
In Kate Seredy's novel 'The Singing Tree', Chapter 3 is titled 'The Young Master'. This book is set during World War I and follows the lives of two cousins, Jancsi and Kate, who come from a Hungarian farming family.
In this chapter, we learn more about Jancsi and his development into a young man. He is eager, enthusiastic, and has a strong sense of responsibility, especially when it comes to taking care of the family farm. The significance of 'The Young Master' in this chapter lies in Jancsi's desire to prove himself capable and trustworthy in the eyes of his family and community.
The title, 'The Young Master', reflects Jancsi's determination to step into a more mature role. A key part of this chapter involves Jancsi dealing with new challenges and learning valuable life lessons that contribute to his growth.
This theme of growth is central to the novel as it portrays how young people come of age and adapt to the changes and hardships brought about by war. By emphasizing these personal developments, the author allows readers to explore themes of responsibility, family, and perseverance in the face of adversity.
A device that delivers a current of 15.0 A for 30 seconds transfers approximately 2.81 x 10^21 electrons. This is calculated by first finding the total charge and then determining how many electrons correspond to that charge. The calculations involve using the relationships between current, charge, and the charge of an individual electron.
