\ta gold orenament weight 36g in air and 34 g in water. it is suspected to have copper mixed in it. find the mass of Cu in ornament? D of Cu= 8.9g/cm3, D ofgold = 19.3 g/cm3\ta cubical wooden block of side 20 cm floats partially immerged in water. what mass of lead should be placed over the block so that the block is just immersed.D of Wood = 0.8 g/cm3, D of lead = 14g /cm3, D of water = 1 g /cm3
