Considering the experimental setup in Part A, where the mass is fully submerged. By choosing from the following equations, use Archimedes principle to derive a general formula for ΔM (where ΔM = M - Mapp, and Mapp is the apparent mass), in terms of the density of the object po, density of water pw, and mass of the object M. 1: Mass station, a = 0, so Fnet is 2: Sum of forces acting on the object gives 3: Equating both equations 4: Bouyancy force is 5: Force of gravity is 6: Tension (apparent weight) is 7: Substituting into above equation 8: Cancelling g out and rearranging to get 9: Volume displaced = volume of object, so V is 10: Substituting V out, we find delta M to be匹配题
