- Problem:
- Two cylindrical tubes extend vertically from an enclosed
- cube entirely filled with water. One tube has a radius of 2 cm,
- while the other has a radius of 10 cm. The water levels in the
- tubes are equal, and both tube have pistons resting on the tops
- of the water columns.
-
- (6) If the smaller piston is pushed 5 cm down into
- the tube, what is the change in the water level of
- the other tube?
-
- Water is an incompressible fluid, so the change in volume in
- one tube must be reflected by an equal change in volume in the
- other tube. The change in volume in the smaller tube is
