Hello I was wondering if anyone could help me with question 2 (Passage I: 52 questions portion) in the 2nd physics chapter? The book explains that density and viscosity can be interconverted. The terminal velocity is said to be smaller in a more viscous medium. How is this possible? When considering oil, it is more viscous than water, but it is less dense than water, therefore the density variable would be smaller in the equation resulting in a larger terminal velocity, not smaller.

Is TBR assuming that the more viscous medium is compared to air and therefore a more viscous medium will always have a larger density than air resulting in a smaller terminal velocity?

Think sticky. The molecules want to hang on to each other and therefore don't move as quickly in a viscous fluid.

BTW, question 2 in my book is about airplane hulls. Probably a different question.
