When you push a basketball under water you feel the ________ pushing up. When you let go, the ball
b. air
c. buoyant force
When you push a basketball under water, you feel the buoyant force pushing up. This force is a result of the pressure difference between the top and bottom of the submerged ball. To understand this concept, you can consider the following steps:
1. Start by recalling Archimedes' principle, which states that the buoyant force exerted on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
2. To calculate the buoyant force, you need to find the weight of the water displaced by the submerged basketball. You can determine the volume of the basketball by using its dimensions and the formula for the volume of a sphere (V = 4/3 * π * r^3).
3. Next, calculate the weight of the displaced water by multiplying the volume of water displaced by the density of water (ρ = 1000 kg/m^3).
4. The buoyant force is equal to the weight of the displaced water, which acts in the opposite direction of gravity. Therefore, when you push the basketball under water, the buoyant force pushing up counteracts the force of gravity, creating the sensation you feel.
In the given options, the correct answer is c. buoyant force.
