Question 7 A solid steel sphere of radius 20 cm has a density of 2000 kg/m³. Thesphere is then submerged in a fluid whose density is 1500 kg/m³.(a) What is the true weight of the sphere?(b) What is the buoyant force on the sphere?(c) What is the apparent weight of the sphere?Question 8 A pipe whose initial diameter is 20 cm runs horizontally for 15 m. Thefluid flows through this part of the pipe with a velocity of 12 m/s. Then, the pipe bendsupwards and rises to the second floor which is 10 m above the ground floor. At thispoint the pipe then constricts to a radius of 5 cm and runs for a final 3 m horizontally.Calculate the difference in pressure between the initial part of the pipe and the final partof the pipe. ASsume the density of the water in the pipe is 1000 kg/m³.

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.
