An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The total charge delivered by a current of 15.0 A for 30 seconds is 450 Coulombs. Approximately 2.81 x 10^21 electrons flow through the device in that time. This calculation is based on the relationship between current, charge, and the charge of a single electron.

Plants can respond to stimuli in ways that promote bushiness, while animals typically exhibit traits like motility and heterotrophy. Snakes, as reptiles, have a closed circulatory system and a centralized nervous system, distinguishing them from simpler organisms. Understanding these concepts helps clarify the distinct characteristics of plants and animals. ;
