An object floating in water has 1/2 (one half) of its volume above the surface of the water. How does its density compare to the density of the water? Group of answer choices 1.5x the density of the water (one and a half) 1/2 the density of the water 2x the density of the water 1/4 (one forth) the density of the water

A hollow spherical iron shell floats almost completely submerged in water. The outer diameter is 66.1 cm, and the density of iron is 7.87 g/cm³. Find the inner diameter. Number Units

A balloon is released from a tall building. The total mass of the balloon including the enclosed gas is 2.0 kg. Its volume is 5.0 m?. The density of air is 1.3 kg/m. 12. What is the average density of the balloon? A) 0.2 kg/m3 B) 0.4 kg/m3 C) 0.8 kg/m D) 1.0 kg/m E) 1.2 kg/m3 13. Will the balloon rise, fall, or remain stationary, and why? A) The balloon will fall because its density is greater than that of air. B) The balloon will remain stationary because its density is less than that of air. c) The balloon will rise because the upward buoyant force is greater than its weight. D) The balloon will fall because the upward buoyant force is less than its weight. E) The balloon will fall because the downward buoyant force is greater than the upward buoyant force.
