An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The articulation between the sternum and the costal cartilage of ribs 2-7 is classified as a synovial joint due to its fluid-filled cavity that permits movement. This distinguishes it from other types of joints such as symphyses and sutures. Understanding this classification aids in knowing the functional anatomy of the thoracic region. ;
The total charge flowing through an electric device with a current of 15.0 A for 30 seconds is 450 Coulombs. This corresponds to approximately 2.81 x 10^21 electrons flowing through the device. The calculation involves using the formulas for charge and the charge of a single electron.
