Answer 2

Calculation of Pressure at the Bottom of the Aquarium

To calculate the pressure at the bottom of the aquarium, we can use the formula:

Pressure = Density × Gravity × Height

Given: - Height of the water in the aquarium = 32 cm - Length of the aquarium = 50 cm - Width of the aquarium = 20 cm

We need to find the pressure at the bottom of the aquarium.

First, let's convert the height of the water from centimeters to meters: - Height = 32 cm = 0.32 m

Next, we need to calculate the density of water. The density of water is approximately 1000 kg/m³.

Now, we can calculate the pressure at the bottom of the aquarium using the formula mentioned above:

Pressure = Density × Gravity × Height

Substituting the values: - Density = 1000 kg/m³ - Gravity = 9.8 m/s² - Height = 0.32 m

Pressure = 1000 kg/m³ × 9.8 m/s² × 0.32 m

Calculating the pressure:

Pressure = 313.6 Pa

Therefore, the pressure at the bottom of the aquarium filled with water is approximately 313.6 Pascal (Pa).

Calculation of the Weight of Water in the Aquarium

To calculate the weight of water in the aquarium, we can use the formula:

Weight = Volume × Density × Gravity

Given: - Length of the aquarium = 50 cm - Width of the aquarium = 20 cm - Height of the water in the aquarium = 32 cm

We need to find the weight of water in the aquarium.

First, let's convert the dimensions of the aquarium from centimeters to meters: - Length = 50 cm = 0.5 m - Width = 20 cm = 0.2 m - Height = 32 cm = 0.32 m

Next, we need to calculate the volume of water in the aquarium. The volume of water can be calculated using the formula:

Volume = Length × Width × Height

Substituting the values: - Length = 0.5 m - Width = 0.2 m - Height = 0.32 m

Volume = 0.5 m × 0.2 m × 0.32 m

Calculating the volume:

Volume = 0.032 m³

Now, we can calculate the weight of water in the aquarium using the formula mentioned above:

Weight = Volume × Density × Gravity

Substituting the values: - Volume = 0.032 m³ - Density = 1000 kg/m³ - Gravity = 9.8 m/s²

Weight = 0.032 m³ × 1000 kg/m³ × 9.8 m/s²

Calculating the weight:

Weight = 313.6 N

Therefore, the weight of water in the aquarium is approximately 313.6 Newtons (N).
