President Jimmy Carter used an ad hoc structure for his White House staff organization, allowing cabinet secretaries and assistants to report directly to him. This method enables quick communication and decision-making. It differs from other organizational structures, like the pyramid and circular models, which impose more layers and shapes to communication. ;
To determine the number of electrons flowing through an electric device with a current of 15.0 A for 30 seconds, we first calculate the total charge as 450 C. Dividing this total charge by the charge of a single electron (approximately 1.6 × 10^{-19} C) gives us around 2.81 × 10^{21} electrons. Hence, about 2.81 × 10^{21} electrons flow through the device during this time period.
