To calculate the maximum mass that can hang without sinking from a Styrofoam sphere in water, we need to use the concept of buoyancy. The buoyant force can be calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object. The density of the Styrofoam is given as
. The maximum mass that can hang without sinking from the Styrofoam sphere in water is 65.4 kg.
To calculate the maximum mass that can hang without sinking from a Styrofoam sphere in water, we need to use the concept of buoyancy. Buoyancy is the upward force exerted on an object submerged in a fluid, such as water. The buoyant force can be calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
The density of the Styrofoam is given as 32 kg/m3. Let's assume the diameter of the Styrofoam sphere is 50 cm, which means the radius is 25 cm or 0.25 m.
The volume of the Styrofoam sphere can be calculated using the formula V = (4/3) * π * r3, where V is the volume and r is the radius. Plugging in the values, we get V = (4/3) * 3.14 * (0.25)3 = 0.0654 m3.
The mass of the water displaced by the Styrofoam sphere can be calculated using the formula m = ρ * V, where m is the mass, ρ is the density, and V is the volume. Plugging in the values, we get m = 1000 kg/m3 * 0.0654 m3 = 65.4 kg.
Therefore, the maximum mass that can hang without sinking from the Styrofoam sphere in water is 65.4 kg.
