As shown in the figure, a container has a vertical tube, whose inner radius is 32.00 mm, connected to it at its side.
 
  An unknown liquid reaches level A in the container and level B in the tubelevel A being 5.0 cm higher than level B. The liquid supports a 20.0-cm high column of oil, between levels B and C, whose density is 460 kg/m3. What is the density of the unknown liquid?
 
  A) 1800 kg/m3
  B) 2000 kg/m3
  C) 1400 kg/m3
  D) 1600 kg/m3
  E) 1700 kg/m3

Question 2

A sphere is constructed of two concentric parts. The inner part is a solid sphere of radius 10.0 cm made of a material with density 4000 kg/m3.
 
  The outer part is a spherical shell with inner radius 10.0 cm and outer radius 20.0 cm. The material in the outer shell has a density
  9000 kg/m3.
  (a) What is the mass of the sphere?
  (b) What is the average density of this sphere?
  What will be an ideal response?
