What is the density of a mass of 85g occupies a volume of 110cm3?
10 cm is not a volume10 cm3 is a volume.85g / 10 cm3 gives a density of 8.5There are some brass alloys and some bronze alloys that have a density of 8.5Brass is an alloy of zinc and copper (and often other metals).Bronze is an alloy of copper and tin (and often other metals)Many other alloys may also have such a density.
What metal has a density of 10.5 per cm3?
There is no metal with that density. The closest would be the beta allotrope of the radioactive metalloid polonium (element 84) : 9.38 g/cm3. Other close matches would be Bismuth - 9.76 g/cm3 Lutetium - 9.84 g/cm3 Thulium - 9.32 g/cm3
How many watts does a standing fan uses?
Very few, really - 50 - 60 would be typical.
How do you work out density of an alloy given its make up?
If you are given its makeup you should be able to make up a list of its constituent metals or elements and the weight fraction of each. Then find the densities of each. Multiply the fraction of each times its density to get the 'weight' of that element in a unit weight the alloy. Add up these 'weights' to get the weight of a unit of the alloy.
What property or properties of non- metals would not be useful when creating a piece of jewelry?
Non-metals tend to be brittle, which makes them less suitable for jewelry that requires durability and the ability to withstand everyday wear. Additionally, many non-metals lack luster and shine, making them less visually appealing for decorative purposes. Their lower density and strength compared to metals can also limit their use in jewelry that needs to maintain structural integrity.
Is low density a metal or nonmetal?
Low density is a physical property that describes how closely packed the particles are in a substance. It is not related to whether a substance is a metal or nonmetal. Metals and nonmetals can exhibit low density depending on their atomic structure and arrangement.
What is the density of a metal nut?
The density of a metal nut can vary depending on the type of metal it is made from. Common metals like steel have a density of around 7.85 g/cm^3, while lighter metals like aluminum have a density of about 2.7 g/cm^3. To determine the exact density of a specific metal nut, you would need to know its material composition.
Would 1.4 sink or float?
Assuming that the medium in which it is floating/sinking in is water, It would sink since its density is higher than that of water (1.0gcm^-3)
What is radar made out of?
Various metals, plastics, foam, and paint. It is the materials found in the typical electronics one would see in a common electronics store.

If you had a object with a density of 1.12 gcm3 would it sink or float in a container of salt water that has a density of 1.35 gmL why?
The object would float in the salt water. This is because the object's density (1.12 g/cm3) is less than the density of the salt water (1.35 g/mL), making it less dense than the surrounding medium and causing it to float.
Compared to a bar of pure gold what is the density of a pure gold ring?
The density of a pure gold ring would be slightly lower than a bar of pure gold because pure gold rings often contain other metals like copper or silver in their alloy. The addition of these metals decreases the overall density of the ring compared to pure gold.
In which of the following would refraction occur?
Refraction occurs when light passes through a medium with a different density, such as air to water or air to glass.
What is the density anomaly?
Density anomaly refers to a situation where a substance does not follow the typical trend of increasing or decreasing in density with a change in temperature. For example, water has a density anomaly where it reaches its maximum density at 4 degrees Celsius, causing it to behave differently from most other substances.
How do you separate aluminium from iron without a magnet?
One way would be to find a liquid that is chemically inert to both metals and has a density between that of iron and that of aluminium. In such a liquid, the aluminium would float and the iron would sink.
What does the term density and refractive index mean?
The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
What would cause a change in the speed of a mechanical wave?
A change in the medium through which the wave is traveling, like a change in material or temperature, can affect the speed of a mechanical wave. Additionally, a change in the tension or density of the medium can also impact the wave speed.
