What is the size of the buoyant force on a 31.0 N ball that is floating in fresh water?
I have no idea. You have to know where the waterline is on the ball.
Oh, sorry, if it is floating and weighs 31, then the water is pushing up with 31 N
To determine the size of the buoyant force on a ball floating in fresh water, you need to consider the fundamental principles of buoyancy. The buoyant force is the upward force exerted on an object submerged or floating in a fluid, and it is equal to the weight of the fluid displaced by the object.
In this case, you have a ball floating in fresh water. To find the buoyant force, you need to determine the weight of the water displaced by the ball.
The weight of an object can be calculated using the equation:
Weight = mass x gravity
The mass of the ball is not provided, but we can still solve for the buoyant force size using the given information.
Since the ball is floating, it experiences an upward buoyant force of the same magnitude but opposite direction to its weight. In other words, the buoyant force is equal to the weight of the ball.
Weight of the ball = 31.0 N
Therefore, the buoyant force on the ball in fresh water is also 31.0 N.
