Final answer:
To calculate the extra force exerted against the bottom of the jug when a cork is pounded into place, we can use the concept of pressure.
Step-by-step explanation:
In order to calculate the extra force exerted against the bottom of the jug, we can use the concept of pressure. Pressure is defined as force per unit area. We can calculate the pressure exerted by the cork using the formula:
Pressure = Force/Area
Since the cork is in direct contact with the wine, the area of contact between the cork and the wine is equal to the area of the cork. We can calculate the area of the cork using the formula for the area of a circle:
Area = pi * radius^2
Once we have the pressure, we can calculate the force exerted against the bottom of the jug by multiplying the pressure by the area of the bottom of the jug.
