An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?

Answer (2)

The suffix "ai" is not associated with hormonal contraceptives, as it does not represent a known hormone in this context. In contrast, the other options relate to hormones used in contraceptive methods. Therefore, "ai" is the correct answer. ;

In a device delivering a current of 15.0 A for 30 seconds, approximately 2.81 x 10^21 electrons flow through it. This is calculated using the relationship between current, charge, and time. The total charge is found to be 450 C, which corresponds to about 2.81 x 10^21 electrons based on the charge of a single electron.
