To determine how many electrons flow through an electric device with a current of 15.0 A for 30 seconds, we first calculate the total charge, which is 450 C. Then, using the charge of a single electron (1.6 x 10^{-19} C), we find that approximately 2.81 x 10^{21} electrons flow through the device.

A political party is defined as an organization that influences the government by getting its members elected to public office. They campaign, formulate policy platforms, and build public support to achieve this goal. This process is vital for democracy as it allows for representation and choice in governance. ;
