An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
A device with a current of 15.0 A for 30 seconds delivers a total charge of 450.0 C . This charge corresponds to approximately 2.81 × 1 0 21 electrons flowing through the device. The calculation uses the relationship between current, charge, and the charge of an electron.

In the given graph, we are looking at the movement of the supply curve, denoted as a shift from S to S 1 . The supply curve visually represents the relationship between the price of a good and the quantity of the good that producers are willing to supply.
Understanding Supply Curve Shifts :
A shift to the right ( S to S 1 ) indicates an increase in supply. This means that at every price level, a larger quantity of the good is supplied than before.
A shift to the left would indicate a decrease in supply, meaning that at every price level, a smaller quantity of the good is provided.
Identifying the Change in the Graph :
The shift on the graph is moving from S to S 1 towards the right. This reflects an increase in supply.
Therefore, the shift illustrated in the graph represents an increase in supply . This change can occur due to various factors such as technological advancements, a reduction in production costs, or an increase in the number of suppliers. As a result, at the same prices, producers are willing and able to supply more quantity than before.
Thus, the correct multiple-choice option is: an increase in supply .
