Final answer:
To accurately determine the amount of salt in a tank after 11 minutes, additional information on the concentration and volume of saltwater introduced, as well as the rate of introduction, is required.
Step-by-step explanation:
The student has asked about the amount of salt in a tank after 11 minutes when a series of events involving saltwater has occurred. To answer this question, we would need more information about the events that took place regarding the saltwater addition. This could include information on the concentration of the saltwater, the volume of saltwater added, and the rate at which it was added. Without these details, it is not possible to give an accurate answer from the options provided.
In general, the principles involved in such a problem would involve understanding the concentration of the saltwater solution and the mixing process. The density of substances can also play a role when discussing buoyancy, as seen in the provided example where the density of a human body is compared with that of freshwater and saltwater to determine what fraction will be submerged.
It is important to gather all the relevant data before attempting to calculate the final concentration of salt in the tank.
