Why does an object that is more dense the liquid it is floating float?
An object that is more dense than the liquid it is floating in will sink because of buoyancy. The buoyant force acting on an object is equal to the weight of the fluid displaced by the object. If the object is more dense than the liquid, the weight of the object is greater than the buoyant force, causing it to sink.
How much more does an object weigh after it has been submerged out of water?
Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.
How do you calculate find the density of an object that floats?
If you can determine the volume fractions of the object that are above and below the water, then you can find the density of the object by multiplying the density of the fluid it floats in by the fraction of the volume that is below the surface of the liquid. Another, more complex way is to weigh the object alone then attach it to one arm of a balance to weigh the object when it is floating. As it floats it will displace an amount of liquid equal in weight to the total object. The decrease in weight will be proportional to the fraction of the object that is submerged. As an example: If an object weighed 100 grams out in the air but only required 20 grams to counterbalance its weight when it is floating, and the fluid it was floating in was water, then the density of the object would be (1 g/cubic centimeter)·(100-20)/100 = 0.8 g/cubic centimeter.
Is volume of liquid displaced by a floating cork more or less than the volume of the cork?
If the cork is floating, then part of it is underwater and part of it is abovewater. The part that's above water is not displacing water, so the volumedisplaced is less than the total volume of the cork.Here's a mantra that will, come in very handy if you memorize it and thenfile it away until you need it:"A sinking object displaces its volume.A floating object displaces its weight." I can't think of any way that an object in water could displace morethanits volume.
How does the sound of an object change when it is underwater, is it louder or softer compared to when it is in the air?
When an object is underwater, the sound it produces is louder compared to when it is in the air. This is because sound travels faster and more efficiently in water than in air, resulting in a louder sound underwater.
What planet makes an object weigh the most?
jupiter is the planet which makes the object's weigh more
Why do some things float and some dont?
A floating object has a density less than what it is floating in. If an object has more density than the medium it is placed in, the medium will be unable to hold the object. The object will, therefore, sink.

An object that is more dense than the liquid it is floating in will sink because of buoyancy. The buoyant force acting on an object is equal to the weight of the fluid displaced by the object.

Does water weigh more when an object is placed in it?
no

Does a hot or cold object weigh more?
wow what a question!! well i don't know but hot air rises so cold would probably weigh more..

Do larger object weighs more than smaller object?
Not necessarily. Weight is the force of gravity acting on an object, so it depends on the mass of the object. A larger object may weigh more than a smaller object if it has more mass, but size alone does not determine weight.
How underwater leaves are different from floating leaves?
Underwater leaves typically have thin, delicate structures, lack a waxy coating, and have less prominent veins compared to floating leaves. Floating leaves are typically thicker, have a waxy coating to repel water, and often have more pronounced veins to support them on the water surface. Additionally, the photosynthetic adaptations and gas exchange mechanisms differ between the two types of leaves.
Do people float more easily in salt water or fresh water?
An object floats because the amount of water it displaces weighs more than the object floating. If the fluid in which something is floating weighs more than water the object will float higher. When salt disolves in water it makes the water heavier, causing the object to float higher. The floating object can be a boat, a piece of wood or a person, it doesn't really matter. The principles of physics are applied equally.
