The Lift and the Floating Object
Public Test. This edition's content and difficulty rating are still under review.
An object floats freely in a tank of water. The tank is inside a lift that begins accelerating steadily upwards. After the water settles relative to the lift, does the fraction of the object's volume below the water surface increase, decrease or stay the same? Treat the liquid and object as incompressible and use the same uniform acceleration throughout the tank.

About Tier 5 - Singularity
The highest challenge tier, usually requiring deep or non-obvious reasoning.
