No real object is massless. Even a balloon has the mass of the balloon plus the mass of the entrained gas.
But if the buoyancy of the entrained gas (hydrogen, helium) allows the balloon to float away, then it will displace no water. Even so, it still has mass.

∙ 10y agoIf a balloon has no mass, then it has no weight, and doesn't need to displace
any water in order to float on the surface. So, unless someone comes along
and sits on it, the balloon displaces no water, whose weight is likewise zero.

A man first swims in seawater then in river water.Compare the weight of seawater and the riverwater displaced by him?
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
What relation do you find between the weight of the floating body and the waight of water that is displaced?
They are equal.When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down.Note - relation between volume(v) mass(m) and density(d) : d = m/v
The upward buoyant force on a body immersed in a fluid is equal to what?
The upward buoyant force is simply equivalent to the weight of an amount of the fluid that would occupy the same space (same volume). The total upward force on the body, if freely floating, would be found by subtracting the downward force of the body's own weight. So for example, the buoyant force on a balloon filled with air submerged in water would be equal to the weight of the same-size balloon filled with water suspended in air.
How does buoyancy make things float?
Not entirely. A vessel will float provided its displaced weight is such that there is ample freeboard remaining. If there is no freeboard, there will be nothing to prevent the water from coming inboard and sinking the vessel. On a small boat, buoyancy bags will prevent the boat from sinking to the bottom of the sea, even if filled with water.
Why does ships float on water?
because the force of the water (thrust) is holding the weight of the ship as the ship weight is evenly balanced so no side of the ship is too heavy when compared to the other side my name is Farahan Ali and Charlee cowee
What is the weight of water displaced by the nearly massless 1 liter balloon?
Whatever the actual weight of the balloon is, if you just set it on the water, then it displaces an amount of water whose weight is equal to the balloon's weight, and then it sits there and stops displacing. Just like any other floating object. If you force the balloon completely underwater by 'helping' it with added force, then it displaces 1 liter of water, which weighs 9.8 newtons (2.205 pounds).
How can you measure the volume of air inside a ballon?
Probably the simplest way would be to fill a container having a known volume (say, a 5 gallon bucket) with water right to the top, weigh it, then push the balloon under the water. The water displaced by the balloon will spill out. (Your hand will displace water too, which screws things up, so use something like a stick to push the balloon all the way in.) Now take the balloon out of the water and weigh the bucket again. The difference between the earlier weight and the final weight is the weight of the water that the balloon displaced. The density of water is 1 gram per cubic centimeter (cc), so (to a very good approximation) the volume of air in your balloon in cc is the same as the weight of the displaced water in grams.
Buoyant force of a rock submerged in water compared to the weight of the water displaced by the rock?
The buoyant force is equal to the weight of the displaced water.
What is the bouyancy of air?
Bouyant force was described by Archimedes to be equal to the force due to gravity of the substance displaced by the object. So in the case of a balloon in water the bouyant force is equal to the force of weight of the water that the balloon displaces otherwise known as the (volume of the balloon)*(density of water)*gravity. Hope that helps
What is the relationship between buoyant force and the volume of water displaced?
Buoyant force is equal to the weight of the water displaced.
Is it true that If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater?
the weight of the displaced water is equal to the weight of the object
The volume of the displaced water is equal to the volume of the portion of the object that's above the surface of the water?
This statement is not correct. The weight of the water displaced by a body in it, is equal to the buoyancy force that the body will experience. In the case the body floats on the surface of water, the weight of the water displaced by the body is equal to the weight of the body.
Why does a ship floats on water answer based on archemedis principel?
Weight of ship = weight of (displaced) water.
What is Archimedes princible?
Archimedes principle states that : The force of buoyancy is equal to the weight of the displaced water. If the weight of the water displaced is less than the weight of the object , the object will sink. Otherwise the object will float , with the weight of the water displace equal to the weight of the object.
How does the buoyant force on a fully submerged object compare with the weight of the water displaced?
The buoyant force on any object in water is equal to the weight of the displaced water, regardless of how much of the object is submerged.

How does the weight of water displaced compare to buoyant force?
They are equal.
