What is the percentage of asbestos is considered dangerous?
Items with greater than 1 percent of asbestos minerals are considered to contain asbestos.
What factors detremine the order of items in a news bulletin?
news values are key here. the news item that has most of the news elements should be placed first. it is assumed that the most important news items will come first.
An order is placed for n items each costing p dollars and twice as many items each costing 9 dollars more. Write a simplified expression for the total cost of the order?
The expression is np + 2n(p+9). This can be simplified into 3np + 18n.
What are side tables used for?
Side tables are usually used in living or family rooms as accent pieces. They are usually placed beside seats and are used to hold items such as lamps.
Which statement is true about the population proportion of defective pieces in the 2000 items?
The statement that the proportion of defective pieces is not less than 0 nor greater than 1.
Would greater density float or sink?
greater density items wood tend to sink, they are heavier then items of less density with same displacement size
Why does an egg sink in fresh water but floats in salt water?
Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.

What Items float on water?
Ones that have a density lower than 1g/cm3.
What else besides an egg float in salt water and sinks in fresh water?
It depends entirely on the amount of salt in the water. Pure water has a density of 1 kg/L. Any item that is less dense than 1 kgL, will float. Items with a greater density will sink. As you increase the salinity of water, the density of the salt adds to the water's density. The Dead Sea, for example, has a high saline level (31%) and it's density is 1.24kg/L. An average sized person can easily float in these waters.
What items will float in water?
Ones with less density than water. No matter what the mass is, as long as it is less dense than water, it will float.

Would a ship will float more in salt water or fresh water?
The more salt in water the more buoyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea.The density of the salt water is greater than the density of an object. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the item doesn't float in freshwater.We call the amount of mass in a given amount of space the density. For instance, we could measure the mass of fresh water (like water from a stream) in a container. We could then determine the density if fresh water. However, if we filled the same container with salt water, it would have more mass because the ocean water has the mass of pure water plus the mass of the salt.Since there is more mass in the same volume, ocean water has a greater density then fresh water.For something to float, it must have a density less than in what it is floating. This means that steam, which is less dense than air, rises (or floats) in the air.It may seem odd that an enormous ship can float when steel is denser than water. However, if you look at the entire ship you see that there are many places filled with things less dense than water, like air. This means that the density of the entire ship is less dense than that of water and it floats.
What floats best on water?
Shapes that float best on water include, anything that is light,and it also depends on the items/ object's density.
How does water sink and float?
Water in water sinks/floats depending mostly on salinity and temperature, note that these two items effect the density of water.
If an object sinks in water what is its density as compared to the density of the water?
If the water is denser than the object it will definitely float. However a denser object will not always sink. The idea of something "sinking" depends on what action you are talking about. It is obviously true that very heavy boats do not "sink" but float happily on the surface of water. (Imagine a simple aluminum row boat where aluminum is almost three times the density of water.) If the boat is submerged however, it stays submerged. The operative principle of physics says that the boat displaces a volume of water with a weight equal to the weight of the boat that is floating, so obviously boats are shaped the way they are to displace enough water to keep them above the surface. So, the simple answer is that an object with a density greater than water will not float to the surface if it is submerged but an object with a density less than water will float to the surface. If you wish to consider complexities beyond merely the density, then you can include the phenomenon of surface tension in keeping small objects floating even if they are more dense than water. That is a small force relevant for small objects and a topic of such complexity that it is not likely to be part of the answer to the question that was posed.
Does hot water need salt to make something float?
It would depend on the item of course... it would take an awful lot of salt to make a bar of steel float. Likewise, a sealed empty bottle might float on either cold or hot water. However, water will expand when heated, thus reducing the density of the water. Salt will increase the density of the water. It is possible to find some items that would float in cold water, but not in boiling water without compensating with something like salt.
