An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To understand why a company's sales declined, descriptive analysis is the most effective type to use. This analysis summarizes historical data to identify trends and factors affecting sales. Other analyses like causal or predictive are not focused on understanding past performance directly. ;
The total charge delivered by the device is 450 coulombs, which corresponds to approximately 2.81 x 10^21 electrons flowing through it in 30 seconds. This calculation uses the relationship between current, time, and the charge of an electron. Thus, we find that about 2.81 x 10^21 electrons pass through the device during the specified time.
