In uniform circular motion, instantaneous velocity is tangent to the circular path.

Instantaneous acceleration (centripetal) is directed toward the center, making the two vectors perpendicular to each other.

Explanation

When water freezes, it forms an open hexagonal structure due to hydrogen bonding.

This structure makes ice less dense than liquid water, which is why ice floats on water.
