Answer 2

Can a Metal Ball with Air Inside Float in Water?

Yes, a metal ball with air inside can float in water under certain conditions. The ability of the metal ball to float depends on its density compared to the density of water. If the density of the metal ball is less than the density of water, it will float. However, if the density of the metal ball is greater than the density of water, it will sink.

The buoyant force acting on the metal ball is determined by the difference between the weight of the water displaced by the ball and the weight of the ball itself. If the buoyant force is greater than the weight of the ball, it will float. Conversely, if the buoyant force is less than the weight of the ball, it will sink.

The relationship between the density of the metal ball, the density of water, and the buoyant force can be expressed using the following formula: ``` F = gV = 1,3 * 10 * 0,3 = 0,39 ``` Where F represents the buoyant force, g is the acceleration due to gravity, and V is the volume of the water displaced by the ball.

The density of the metal ball can be calculated using the formula: ``` m = F / g = 0,39 / 10 = 0, 039 = 39 ``` Where m represents the density of the metal ball.

Therefore, if the density of the metal ball is less than the density of water, it will float; if it is greater, it will sink.

In conclusion, whether a metal ball with air inside can float in water depends on the relative densities of the ball and water. If the ball's density is less than that of water, it will float; if it is greater, it will sink.
