What else can I help you with?
Is the density of warm water greater than cold water?
Yes, cold water is dencer indeed
Is buoyant force on the lump of gold greater than less than or equal to the gold's weight?
The buoyant force on the lump of gold is less than its weight. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the submerged object. Since gold is denser than most fluids, the weight of the gold will exceed the weight of the fluid it displaces, resulting in a buoyant force that is less than the weight of the gold itself.
Why do scissors sink?
Scissors sink because they are made of metal, which is denser than water. When an object is denser than the fluid it is placed in, it displaces less water than its weight, resulting in a net downward force. This causes the scissors to overcome the buoyant force provided by the water, leading them to sink.
How is density used in real life?
Density has its connection with buoyancy.The ability of an object to "float" when it is placed in a fluid is called buoyant force. If an object is less dense than the fluid in which it is placed, it will "float" on the fluid. If it is more dense than the fluid, it will "sink." For example: Metal ships can float because their total density is less than that of the water that they float on.
A block of wood of mass 3.5 kg floats in waterCalculate the buoyant force on the block?
mass of the block is 3.5kg so block is floats on the water then we are say density of the body less than the water there is only along normal force acting the body buoyant force=mass*gravity B=3.5*9.8 B=34.8Kg/m/sec^2. thank you
Why is air more buoyant than water?
Air is more buoyant than water because it has a lower density. The density of an object determines its buoyancy - objects with lower density than the fluid they are in will float. Air is less dense than water, so objects are more likely to float in air than in water.
Are PFDs more buoyant in deep water than in shallower water?
yes
Why do objects seem to be lighter in water than in air?
Objects are more buoyant in water than in air.
Why do chlorine dispensers float?
Because they are more buoyant than the water.
Why does a ship sink lower in hot water than in cold?
The ships go lower in hot water because it is less dense than the cold water. The molecules in the cold water are more stationary than in warn water when they are moving faster so it is not as solid.
Why are you more buoyant in a swimming pool or a lake than on land?
Buoyancy is a force exerted by a fluid that opposes the weight of an object immersed in it. In water, the buoyant force counteracts the gravitational force acting on your body, making you feel lighter and more buoyant. This is why you may feel more buoyant in a swimming pool or a lake compared to on land.
Which fluid produces greater buoyancy air or water?
Water produces greater buoyancy than air because water is denser than air. This means that an object will displace more water and experience a greater buoyant force when submerged in water compared to when surrounded by air.
Why do ship sink deeper in fresh water than in salt water?
Any thing from people to ships are more buoyant in freshwater than in saltwater. Buoyancy is determined by the downward and upward force of an object. Also, saltwater weighs more than freshwater, so objects are more buoyant in the heavier water.
Why do ships sink deeper in fresh water than in salt water?
Any thing from people to ships are more buoyant in freshwater than in saltwater. Buoyancy is determined by the downward and upward force of an object. Also, saltwater weighs more than freshwater, so objects are more buoyant in the heavier water.
Why can you lift heavy objects in water easily than to air?
You can lift heavy objects more easily in water than in air because water provides more buoyant force than air due to its higher density. This buoyant force counteracts the weight of the object, making it feel lighter in water.
Will sea water or river water provide more buoyant force?
Sea water will provide more buoyant force than river water because seawater is denser due to its higher salinity. The higher density of seawater results in greater buoyant force acting on objects floating in it compared to river water.
Why does buoyancy force change in the fluid temperature high temperature less buoyancy low temperature high buoyancy now why is that?
Buoyant force is directly proportional to the mass of the liquid that is displaced by an object that is submerged in it. The mass of a certain volume of a liquid is directly proportional to the density of that liquid. The more dense the liquid is, the greater is the buoyant force. For water that is over 4 degrees Centigrade in temperature, the warmer the water, the less dense is the water. In other words, warm (summer) water is less buoyant than is cold (winter) water, because the density of warmer water is less than is the density of cooler water. Similarly, salt water is more buoyant than fresh water, because the density (in grams per cubic centimeter, or pounds per cubic yard) of salt water is greater than is the density of fresh water.
