Question

A graduated cylinder filled with water rests upside down in a container of water at 0 C. The water is 7.00 cm deep. Attached to the base of the cylinder is a small ring (but since the cylinder is upside down, the ring is at the highest elevation, available for grabbing). The base of the cylinder has mass 10.0 grams with ring included. The cylinder itself has radius 3.00 cm, height 40.0 cm, and mass 100.0 grams (including the base and ring). Bridgette has a scale that can read hanging weight (but, as so often happens, reads in grams instead of Newtons). She hooks the scale to the ring on the bottom of the cylinder and lifts, so that the base of the cylinder lifts 5.00 cm, but remains beneath the surface of the water. She is amazed that the cylinder remains full of water, seemingly all the way to the base. What is the reading on the scale? ;) (The mass density of the cylindrical part of the graduated cylinder is 1.00 grams per cm3 .)
