An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To match sentences and questions with their corresponding responses, we need to understand the context of each interaction. Here is how the matching works:
Sorry, what did you say?
Response: f. Don't worry. I'll say it again.
This response fits because when someone didn’t hear what was said, it’s appropriate to offer to say it again.
What do you mean by 'a problem'?
Response: a. Nothing. I'll explain later.
This response suggests that the speaker will elaborate or clarify their statement at a later time, which is appropriate when there is confusion about a term or phrase.
Sorry, I keep losing the signal.
Response: e. Can I call back later?
This response is suitable because if the signal is poor, it makes sense to suggest calling back at another time.
I'm afraid I can't follow your directions.
Response: b. Never mind. I'll draw you a map.
This response is appropriate because it offers an alternative form of assistance that might be clearer.
Sorry, what was that?
Response: c. I said, I'm going to be late.
In this case, the speaker repeats their initial statement to clarify what was missed.
Sorry, I'm a bit confused.
Response: d. I said, do you come here often?
This matching may not seem immediately logical, but it would apply if the confusion was based on someone not understanding what was asked originally. Reiterating the question might help clarify confusion.
This exercise is designed to help improve listening and communication skills by encouraging understanding and clarity in conversation.
The device delivers a charge of 450 coulombs when a current of 15.0 A is applied for 30 seconds. This amount of charge is equivalent to approximately 2.81 x 10^21 electrons. Therefore, around 2.81 x 10^21 electrons flow through the device during that time period.
