An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The device delivers a current of 15.0 A for 30 seconds, resulting in a charge of 450.0 C. This charge is equivalent to approximately 2.81 x 10^21 electrons flowing through the device. Thus, about 2.81 sextillion electrons pass through it during this time.

The correct statement if a market is in disequilibrium is D) There is excess supply or excess demand.
When a market is in disequilibrium, it means that the quantity demanded does not equal the quantity supplied. This can result in either excess supply (also known as a surplus) or excess demand (also known as a shortage). This imbalance indicates that the forces of demand and supply are not in agreement, which typically leads to adjustments in prices or quantities to reach a new equilibrium.
A determinant of price elasticity of demand (PED) is C) Degree of necessity of the product.
Price elasticity of demand measures how much the quantity demanded of a good responds to a change in its price. One key determinant is the degree of necessity: essential goods tend to have inelastic demand, meaning consumers still buy them even if prices rise. Conversely, non-essential or luxury items often have more elastic demand because consumers can reduce their consumption if prices increase.
What would cause the supply curve for an agricultural product to shift to the right is D) An increase in the productivity of farms.
A rightward shift in the supply curve indicates an increase in supply. This can be caused by improvements in productivity, such as advancements in technology or farming practices, which enable farmers to produce more output with the same amount of inputs.
What would increase the price elasticity of supply (PES) of a product is D) An increase in the time a product can be stored.
The price elasticity of supply measures how much the quantity supplied changes in response to a change in price. If a product can be stored for a more extended period, suppliers can be more responsive to price changes, which increases the elasticity of supply. This storage capability allows producers to wait for favorable market conditions before selling.
