7. The hydrometer shown in has a mass of 0.045 kg. The cross-sectional area of its stem is290 sq. mm. Determine the distance between graduations (on the stem), mm, for specific gravities of 1.00 and 0.90. 8. A tank has a length of 2.5 m and width of 2.0 m and contains water at a depth of 1.15 m. If the tank is subjected to an linear acceleration of 4.25 m/s-2 parallel to the length of the tank, determine the height of the sides such that no water will be spilled.
