An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The device with a current of 15.0 A delivers approximately 2.81 × 1 0 21 electrons in 30 seconds. This calculation uses the relationship between current, time, and charge. The charge of a single electron is approximately 1.6 × 1 0 − 19 coulombs.

To determine how many times the loop will iterate, we need to understand how this type of loop functions. In this case, the loop is a while loop, which means it keeps repeating as long as the condition specified is true.
Here's the loop we're examining:
Set k = 1 While k > 5 Display k End While
The loop starts by setting k to 1.
Next, it checks the condition k > 5.
Since k is initialized to 1, the condition k > 5 is not true because 1 is not greater than 5.
Given that the condition is false at the beginning, the loop body (the part that says Display k) will never be executed.
In conclusion, the loop will iterate 0 times .
Thus, the correct answer is option C) 0.
