TBR fluids and solids

For this question is D the answer because under different kinds of stress, the affected intermolecular bonds are still same?


Also I have couple questions about fluids in general.

1) For turbulence, the formula is Reynolds number = 2pRv/viscosity. Why does turbulence depend on density of the fluid?
2) according to Tbr, when deforming a solid, the stress decreases after reaching ultimate tension strength and then the solid fractures. Why does this decrease?

Bump! Help would be greatly appreciated 🙂

Solids are no longer tested on the MCAT. That's a drawback to using older books.

As for Reynolds number and turbulence, any factor that can affect how the molecules within a fluid stick to one another during flow can impact the nature of the flow.

Sorry if this is bad question but how does density relate to what you said about sticking to one another?
