1) A block of wood has a density of 0.55g/cm^3 and mass of 2,500 g. it floats in a container of oil (the oil%u2019s density is 0.85 g/cm^3). What volume of oil does the wood displace?
2) The bulks modulus of a material, as a meaningful physical property, is applicable to which phases?
3) By what factor is the total pressure greater at a depth of 750 m in water than at the surface where pressure is one atmosphere? (water density: 1.0 * 10^3 kg/m^3, 1 atmosphere pressure: 1.01 *10^5 N/m^3 and g= 9.8m/s^2).
