An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The process described in the question is called osmosis , where water moves through a semi-permeable membrane along a concentration gradient. This is crucial for maintaining cell function and turgor, distinguishing it from active transport and diffusion. Understanding these terms is essential in biology studies. ;
To find the number of electrons flowing through a device with a current of 15.0 A over 30 seconds, we first calculate the total charge as 450 C. Then, by dividing the total charge by the charge of one electron (approximately 1.6 x 10^{-19} C), we find that about 2.81 x 10^{21} electrons flow through the device.
