An object floats for three reasons. One, it is less dense than the solution it is floating in. Such as a piece of wood. Two, the object contains something that is less dense than what it is floating in. Such as a baloon. Three, the shape of the object is such that it does not have enough weight to displace enough of the solution to envelop the object. Such as with any seagoing vessell.
What else can I help you with?
What does the weight of an object that floats have the same value as?
The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
What are the archemedes principle?
The bouyant force on an object is equal to the weight of the fluid the object displaces.
A rectangular barge 7 m long and 2 m wide floats in fresh water how much deeper does it float when its load is a 400 kg horse?
Consider the following - a submerged object displaces its volume, but a floating object displaces its weight. You also know (or can assume) the load is evenly distributed. So you can take the weight of the load (the horse) and apportion the displacement evenly across the boat. Now you are better prepared to calculate the answer.
What happens to the body when the upthrust is less than the weight of the object'?
An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.
Is an object neutrally buoyant when it displaces an amount of water less than its own weight?
No, it sinks
If you know the weight of an object that floats you know the what?
If you know the weight of an object that floats, you can determine the buoyant force acting on it, which is equal to the weight of the fluid it displaces. This information allows you to calculate the object's density, as it will be equal to the density of the fluid it displaces.
Does an object that floats displace water?
Yes. A floating object displaces its own mass in water.
Partially submerged object floats when?
A partially submerged object floats when the weight of the water it displaces is equal to its own weight, creating a balance that allows it to remain buoyant. This is known as Archimedes' principle. If the object's weight is greater than the weight of the water it displaces, it will sink, and if the object's weight is less, it will float completely above the water.
What factors affect an objects ability to sink or float?
the water that it displaces (the amount of water it takes up in the water) is a factor. If the weight of an object is lighter than the weight of the amount of water it displaces, then, it floats. If the weight is higher than the weight of the water it displaces, then the object sinks.
What happends if the weight of an object is greather than the weight of the water?
I assume you mean "What happens if the weight of an object is greater than the weight of the water it displaces." If so, the answer is simple, it sinks. If an objects weighs less than the weight of the water it displaces, it floats.
When an object floats the buoyant force is what the weight of the object?
When an object floats, the buoyant force acting on it is equal to the weight of the fluid that the object displaces. This principle is known as Archimedes' principle. The buoyant force is able to counteract the weight of the object, allowing it to float.
What is the true about an object that floats in water?
An object that floats in water is less dense than the water it displaces. This means that the weight of the water it displaces is greater than the weight of the object itself, causing it to float. Objects that float have a density less than 1 g/cm3.
If an object floats the volume of the displaced water is equal to the volume of the whole object?
Yes, according to Archimedes' principle, when an object floats in a fluid, the weight of the object is equal to the weight of the fluid it displaces. This means that the volume of the displaced water is equal to the volume of the object.
Would an object of 3.7 cm float why or why not?
Floats when it displaces its weight of water; sinks when it's displaced water weighs less than the object. Huh?
What will happen if the weight of an object is greater than the weight of the water that it displaces?
If the weight of an object is greater than the weight of the water it displaces, the object will sink. This is because the buoyant force exerted by the water on the object is not enough to counteract the object's weight, resulting in it sinking in the water.
If the weight of an object is greater than the weight of the water that it displaces what will happen?
The object will sink because its weight is greater than the weight of the water it displaces. According to Archimedes' principle, the buoyant force acting on an object is equal to the weight of the fluid displaced, so if the object weighs more than the water it displaces, it will not be able to float.
Why the forces in a floating are balanced?
In a floating object, the weight of the object is balanced by the buoyant force exerted by the fluid it displaces. This equilibrium occurs because the weight of the object is equal to the weight of the fluid it displaces, resulting in a net force of zero and causing the object to float.
