How can a beach ball can float on water?
A beach ball can float on water because it is less dense than the water, due to the air trapped inside the ball. The buoyant force exerted by the water on the beach ball is greater than the force of gravity pulling it down, allowing the ball to float on the surface of the water.
When will a ball filling with water sink?
The ball will sink when the weight of the water inside the ball plus the weight of the ball is greater than the weight of the amount of water that would fit inside the ball.
Why does a beach ball float when placed in water?
A beach ball floats in water because it is less dense than the water. The air inside the beach ball provides buoyancy, which helps it stay afloat. The buoyant force exerted by the water on the beach ball is greater than the force of gravity pulling it down, allowing it to float.
What forces act on a ball sinking in water?
The main forces acting on a ball sinking in water are gravity, buoyancy, and drag. Gravity pulls the ball downward, buoyancy pushes the ball upward due to water displacement, and drag resists the ball's motion through the water, slowing it down.
What is the speed of a falling ball with the specific gravity of 3.4 in water?
The Specific Gravity of 3.4 water units means that the ball weighs 3.4 Kilograms. (Water has the Specific Gravity of 1.0, which means that 1Litre of water weighs 1 Kilogram) However, this has no bearing on the speed of the ball unless we know the height from which the ball is dropped (I.E how far it has to fall) and at what point in time the measurement of the balls speed is required. The ball will take approximately 1.2 seconds to reach its terminal velocity (the speed at which it can no longer accelerate), in which time it will have travelled (without a calculator) about 5 metres. It is only at this point that the balls final speed can be calculated Hope this helps, but cant do more without knowing more variables.
Can the gravity inside a space station be controlled?
The larger the object, the more 'space' is displaced, and thus, the greater the gravity. The Moon displaces less 'space' than the Earth, so the Moon has less gravity. The space station displaces very little space AND its' shape does not lend itself to taking advantage of the spacial displacement, so it doesn't result in very much gravity. Stand in a swimming pool and hold a beach ball under the water: the pressure of the water on the ball is a simulation of gravity. Hold a tennis ball under the water: far less pressure, yes? Now, hold something with the exact same collective mass as the beach ball (lets say one of those 'noodle' things the kids play with) and you'll have far less pressure on it than on the beach ball. Why? It has the same mass as the beach ball, so why isn't there the same amount of pressure (gravity) on it? Because the 'shape' of it does not lend itself to take advantage of the gravitational pressure. Gravity can, however, be simulated with inertia. If the ship spins... centripical force and all that.
What force makes a golf ball sink in water?
Gravity.
Why does a ball full of air float and not one that is not inflated?
A ball filled with air floats because the air trapped inside it creates buoyancy, which pushes against the force of gravity. An uninflated ball does not have this air-filled buoyant force, so it sinks in water.
What is the diameter of 150kg metallic ball if specific gravity is 12?
First, you have to calculate the ball's volume. Just divide the mass by the specific gravity. Then use the formula for the volume of a sphere. Solve for r (radius). The diameter is twice the radius.
What force is causing the ball to sink?
The force causing the ball to sink is gravity. Gravity pulls objects towards the center of the Earth, which causes the ball to accelerate downward until it reaches the bottom of the water.
Will a tennis ball float or sink?
A tennis ball will float in water because it is less dense than water. The air inside the ball helps to keep it buoyant on the surface of the water.
Why does a bastetball go flat if you leave it out on a winter day?
The air molecules inside the basketball become less active as they cool off and don't bounce off each other or the inside of the ball as much, which lets gravity, and the materials the ball is made of, determine the shape of the ball to a greater extent. Gravity pulls all the parts of the ball straight down tending to make it flat against the ground that is supporting it, and the rubber and plastic of the ball tend to keep it round, but smaller than when the air inside is pushing against it.
