An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The calcium-containing compound that hardens bones is hydroxyapatite, which is primarily composed of calcium and phosphate. Other terms like menisci and trabeculae refer to different bone structures or functions. Hydroxyapatite is crucial for providing bones with their strength and rigidity. ;
The electric device with a current of 15.0 A for 30 seconds delivers approximately 2.81 x 10^21 electrons. This is calculated using the relationship between current, charge, and the charge of an electron. The charge delivered over 30 seconds is 450 coulombs, which corresponds to the calculated number of electrons.
