To find the number of electrons that flow through an electric device delivering a current of 15.0 A for 30 seconds, we calculate the total charge using the formula Q = I × t , which gives us 450 C. Then, using the charge of one electron ( 1.6 × 1 0 − 19 C ), we can determine that approximately 2.81 × 1 0 21 electrons flow during this time period.

Poikilothermic animals depend on their environment for temperature regulation. Alcohol impairs decision-making and can affect sexual health, increasing HIV risk, while conservation efforts like national parks are essential for wildlife protection. However, practices like overgrazing can harm wildlife. ;
