Question

What is the force on the cork when the tank, with a hole of area 4.0 cm² at the bottom and filled with water, is closed with a cork?

Answer 1

To calculate the force exerted against the bottom of the jug when the cork is pounded in, we can use the concept of pressure. The formula for pressure is Force / Area.

Step-by-step explanation:

To calculate the force exerted against the bottom of the jug when the cork is pounded in, we can use the concept of pressure. Pressure is defined as force per unit area.

The formula for pressure is:

Pressure = Force / Area

In this case, the force exerted against the bottom of the jug is equal to the pressure multiplied by the area of the cork.

Given that the cork has a diameter of 2.00 cm and the jug's bottom has a diameter of 14.0 cm, we can calculate the area of the cork and the extra force exerted as:

Area of cork = (π / 4) x (diameter of cork)^2

Extra force exerted = Pressure x Area of cork

Now, we just need to substitute the values into the formulas and calculate the results.
