An unknown object is placed on a balance, which then reads 6.118 g . Its volume is measured to be 3.04 cm3 . Find the density of this object by dividing mass by volume. Express your answer in grams per cubic centimeter to the appropriate number of significant figures.

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)
