A certain coin has a diameter of 21.21 mm, a thickness of 1.95 mm, and weighs 0.04905 N. What is its density?
 
  A) 29.1  103 kg/m3
  B) 7.26  103 kg/m3
  C) 9.25  103 kg/m3
  D) 2.31  103 kg/m3
  E) 71.2  103 kg/m3

Question 2

Two compressible solids are formed into spheres of the same size. The bulk modulus of sphere two is twice as large as the bulk modulus of sphere one. You now increase the pressure on both spheres by the same amount.
 
  As a result of the increased pressure, how is the change in volume of sphere two (V2 ) related to the change in volume of sphere one (V1 )? A) V2 = 2V1
  B) V2 = 4V1
  C) vV2 = V1
  D) V2 = 1/2V1
  E) V2 = 1/4V1
