An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The renal cortex is the outer layer of the kidney, and nephrons are the functional units responsible for filtration and urine production. The statement about the right kidney being higher than the left is false, while the one about the renal medulla is partially true. Therefore, the first and third statements are true. ;
A device with a current of 15.0 A delivers roughly 2.81 × 1 0 21 electrons over a period of 30 seconds. This calculation is based on the total charge delivered and the charge of a single electron. Hence, by using the formula Q = I × t and the properties of electrons, we arrive at the final answer.
