Final answer:
The question relates to calculating the pressure exerted by gasoline in a tank and falls under physics. It involves applying the formula for pressure (P = F/A) and concepts of fluid mechanics, making it appropriate for high school students.
Step-by-step explanation:
The question revolves around the concept of pressure exerted by liquids in a container, which falls under the domain of physics, particularly fluid mechanics. The question appears to be at a high school level of education, as it involves basic principles of pressure, force, and area, and possibly requires use of the equation P = F/A, where P is pressure, F is the gravitational force of the gasoline which is weight, and A is the area over which that force is exerted.
For example, to find the pressure exerted on the bottom of a gas tank, one would need to calculate the weight of the gasoline (mass × acceleration due to gravity) and divide it by the area of the bottom of the tank. Since gasoline has a density of 0.75 kg/L, a 50 kg gasoline mass can be converted into liters, and then the volume can be used to find the depth of the tank, given its width and length. It's also interesting to note the environmental aspect as mentioned, where burning gasoline results in CO₂ emissions, with the example stating that one tank of gasoline will produce about 110 kg of CO₂.
