Clarification:
We need an expression that shows how much water has been drained from the tub. This is represented by v, which indicates how many gallons have flowed out since the plug was taken out. Each gallon removed equates to 8.345 pounds of water, so the weight of the drained water Q in pounds as a function of v can be expressed as:

Where v signifies the number of gallons emptied from the tub.
Have a great day! Let me know if there's anything else I can assist with.
Answer: In contrast, methane consists of one carbon atom and 4 hydrogen atoms. Similar to water, the bonds present are covalent.... Water has strong hydrogen bonding with other molecules, resulting in the need for a significant amount of energy to break these bonds, and its boiling point is around 100 degrees Celsius.
Explanation:
Speed is defined as distance over time. Hence, to determine the distance, we use d = V * t. Plugging in the values yields d = (72 Km / h) * (1h / 3600s) * (4.0 s) = 0.08Km. Thus, during this distracted period, a distance of 0.08Km was covered.
