A 3-kg plastic tank that has a volume of 0.2 m³ is filled with liquid water. Assuming the density of water is 1000kg/m3, determine the weight of the combined system.

The deep body temperature of a healthy person is 37°C. Express this temperature in R, K, and °F. What is the density (kg/m3) of human blood? What is the specific volume (ft³/lbm) of Mercury? Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs underidentical conditions. The buoyancy force, which can be expressed as F, = pairgballoon, Will push the balloon upward. Ifthe balloon has a diameter of 12 m and carries two people, 85 kg each, determine the acceleration of the balloonwhen it is first released. Assume the density of air is p= 1.16 kg/m³, and neglect the weight of the ropes and thecage.
