An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Foxes are likely to develop thicker fur as an adaptation to dropping winter temperatures, which helps them retain heat. While fat deposits and hibernation are also considerations, fur thickness is the most direct physiological response. Genetically based variations can influence these adaptations, but thicker fur is key for survival in cold climates. ;
The total charge flowing through a device delivering a current of 15.0 A for 30 seconds is 450.0 C. This charge corresponds to approximately 2.81 x 10²¹ electrons. Calculations were based on the relationship between current, charge, and the elementary charge of an electron.
