Final answer:
The question pertains to Physics and asks for the values of induced drag and parasite drag at the maximum Lift-to-Drag ratio, but cannot be answered without additional information from problem 11.
Step-by-step explanation:
The question seems to be related to the subject of Physics, particularly focusing on the concept of induced drag (di) and parasite drag (dp) in the context of an aircraft's aerodynamics. Specifically, the question seeks to determine the values of di and dp when the Lift-to-Drag (L/D) ratio is at its maximum. With the information provided, there is insufficient context to determine the correct answer, as key details about problem 11 are not included.
Since problem 11 refers to a previous question or information that's not provided in the text, additional information would be needed to solve for di and dp accurately. However, without that context, answer choice (a) 'Additional information needed' would be most appropriate as it acknowledges the lack of necessary details to determine the values of di and dp at max(L/D) max.
