A woman is enjoying a tropical drink while lying on a beach.  The acceleration due to gravity at her location is 9.78 m/s2. What gauge pressure must exist in the woman’s mouth if she is drinking through a straw extending 0.075 m above the surface of the drink? Assume the drink has a density of 1020 kg/m3.

An ice skater is spinning on frictionless ice with her arms extended outward. She then pulls her arms in toward her body, reducing her moment of inertia. Her angular momentum is conserved, so as she reduces her moment of inertia, her angular velocity increases and she spins faster. Compared to her initial rotational kinetic energy, her final rotational kinetic energy is ______
