A low-density block with a weightof 18.0 N is placed in a beaker ofwater and tied to the bottom ofthe beaker by a vertical string offixed length. As water is steadilyadded to the beaker, the blockbecomes more and moresubmerged.a) When the block is 25%submerged, the tension in thestring is 20.0 N. The string willbreak if its tension exceeds 80.0N. What percentage of the blockis submerged at the instant thestring breaks?%b) After the string breaks theblock bobs around for a while andthen eventually comes to a newequilibrium position, floating atthe water surface in the beaker.What percentage of the block issubmerged when equilibrium isreached?%

Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 43.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). What mass of water is displaced?
A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe has a diameter of 17.0 cm. The lower end of the pipe has a diameter of 6.80 cm. The flow rate of the water in the pipe is 0.0500 .What is the speed of the water at the lower end of the pipe?

You need to determine the density of a ceramic statue. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the statue into a tub of water so that it is completely submerged, the scale reads 17.0 N. What is the density?
A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.
A scale reads 100 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The mass density of aluminum is 2700 kg/m^3. Be careful, you are given mass density instead of weight density, and we are using SI units.i need answer in problem sigfig
