An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Certain cells, like skin and blood cells, divide at faster rates than others due to factors such as cell type, organism's age, and environmental conditions. Cancer cells illustrate rapid division, contrasting with neurons that may not divide. Understanding these differences is crucial in biology. ;
In a device with a current of 15.0 A over 30 seconds, a total charge of 450 C flows. This corresponds to approximately 2.81 × 1 0 21 electrons flowing through the device. The charge of an individual electron is approximately 1.6 × 1 0 − 19 C .
