A 3.2 kg object is attached to a spring with a spring constant of 600 N/m. The other end of the spring is attached to the bottom of a pool.  The volume of the object is 0.09 m3.  The object and the spring are immersed in water.  Determine if the object will float, stay stationary, or sink. Determine the amount that the spring will stretch or compress.

The gravitational force exerted on a solid object is 5.25 N as measured when the object is suspended from a spring scale as in Figure a. When the suspended object is submerged in water, the scale reads 3.98 N (Figure b). Find the density of the object. kg/m3 Scale B MgV

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?

a diving sphere has a mass of 2.05x10^5 kg and an external diameter of 12.0 meters. the sphere initially floats on the surface of the ocean. the density of the sea water is 1025 kg/m^3. a large anchor is then attached to the sphere and it sinks to the ocean floor at a depth of 1.49 km. what is the buoyant force felt by the submerged sphere? what is the tension in the anchor cable?
