To calculate the number of electrons flowing through an electric device with a current of 15.0 A for 30 seconds, we first find the total charge using the formula Q = I × t . This results in a charge of 450 C , which corresponds to approximately 2.81 × 1 0 21 electrons flowing through the device.

Supply and demand work together to determine market prices through their interaction. These forces influence each other's behavior in response to changes in market conditions. The equilibrium price is where the quantity supplied equals the quantity demanded. ;
