An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
React to the statement 'There is a right and wrong way to act in public' with True, because societal norms dictate acceptable behavior.
Justify that actions violating these norms are considered inappropriate.
React to the statement 'Manners shouldn't change over time' with False, because societal values evolve.
Justify that what was polite in the past may not be polite today.
Explanation
Understanding the Task We need to express our initial reactions to two statements about etiquette. The first statement is 'There is a right and wrong way to act in public,' and the second is 'Manners shouldn't change over time.' We must choose True or False for each statement before reading the book and provide a brief justification for our choices.
First Statement - Before Reading For the first statement, 'There is a right and wrong way to act in public,' I choose True.
Justification for First Statement My reason is that societal norms dictate acceptable behavior, and actions that violate these norms can be considered inappropriate or 'wrong.'
Second Statement - Before Reading For the second statement, 'Manners shouldn't change over time,' I choose False.
Justification for Second Statement My reason is that societal values and expectations evolve, leading to changes in what is considered polite or acceptable behavior over time. What was considered polite in the past may not be considered polite today.
Examples
Understanding etiquette is like learning the rules of a game. Just as knowing the rules helps you play the game effectively, understanding etiquette helps you navigate social situations smoothly. For example, knowing when to send a thank-you note or how to properly introduce people can make interactions more pleasant and avoid misunderstandings. These social skills are valuable in both personal and professional settings, contributing to better relationships and opportunities.
The current of 15.0 A flowing for 30 seconds delivers a total charge of 450 C . This charge corresponds to approximately 2.81 × 1 0 21 electrons. Therefore, about 2.81 × 1 0 21 electrons flow through the device.
