Supposed a needle-shaped object is dropped in a large expanse of liquid so that it falls due to gravity under creeping flow conditions. Will it rotate toward a vertical position, toward a horizontal position, or not at all? Explain your reasoning.
Added by Salvador V.
Step 1
" Creeping flow refers to a type of fluid flow where the velocity of the fluid is very low, and the viscous forces dominate over the inertial forces. In other words, the fluid is moving very slowly, and the friction between the fluid and the object is more Show more…

If you lay a steel needle horizontally on water, it will float. If you place the needle vertically into the water, it will sink. Explain why.
A "dip needle" is a small magnet mounted on a horizontal axis so that it can swivel up or down (like a compass turned on its side). Where on Earth will a dip needle point most nearly vertically? Where on Earth will it point most nearly horizontally?
