Answer 2

Calculation of Pressure Increase

To determine the increase in pressure on the table when water with a volume of 3 liters is poured into a container with a bottom area of 930 cm², we can use the equation for pressure:

Pressure = Force / Area

The force exerted by the water on the bottom of the container is equal to the weight of the water. The weight of an object can be calculated using the equation:

Weight = Mass * Gravity

Given that the volume of water poured into the container is 3 liters and the density of water is approximately 1 g/cm³, we can calculate the mass of the water:

Mass = Volume * Density

Converting the volume from liters to cubic centimeters (cm³):

Volume = 3 liters = 3000 cm³

Substituting the values into the equation:

Mass = 3000 cm³ * 1 g/cm³ = 3000 g

The force exerted by the water on the bottom of the container is equal to the weight of the water. Using the value of acceleration due to gravity, g = 9.8 N/kg, we can calculate the force:

Force = Mass * Gravity

Force = 3000 g * 9.8 N/kg

Now, we can calculate the pressure increase on the table by dividing the force by the area of the container's bottom:

Pressure Increase = Force / Area

Pressure Increase = (3000 g * 9.8 N/kg) / 930 cm²

Please note that the given sources do not provide specific information related to the calculation of pressure increase in this context. However, the calculations provided above are based on well-established principles of physics.

Let's calculate the pressure increase using the given values and round the answer to the nearest whole number:

Pressure Increase = (3000 g * 9.8 N/kg) / 930 cm² ≈ 32 Pa

Therefore, the pressure of the container on the table will increase by approximately 32 Pa when 3 liters of water are poured into it.
