An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?

Asked by baby98441

Answer (2)

The total charge delivered by the device is 450 C. This corresponds to approximately 2.81 trillion electrons flowing through the device in 30 seconds. The calculation involves using the current and time to determine charge, and then converting that charge to the number of electrons using the charge of a single electron.

To change words from the nominative case to the accusative and possessive cases, it's important to understand these cases first:

Nominative Case : This is used for the subject of a sentence—the person or thing doing the action.
Accusative Case : This is used for the direct object of a sentence—the person or thing receiving the action.
Possessive Case : This shows ownership or a relationship between things.

Here is how we transform each of the pronouns from the nominative case to the accusative and possessive cases:

I
Accusative: me
Possessive: my


We
Accusative: us
Possessive: our


You
Accusative: you
Possessive: your


She
Accusative: her
Possessive: her


He
Accusative: him
Possessive: his


They
Accusative: them
Possessive: their



Now, let's write three sentences for each case.
Nominative Case:
a. I am going to the store.
b. We are planning a surprise party.
c. She enjoys reading books.
Accusative Case:
a. The teacher asked me a question.
b. Can you help us with the project?
c. The gift was for her .
Possessive Case:
a. That is my favorite book.
b. Our team won the championship.
c. Their dog is very friendly.
