Answer:
4) how charged the object creating the field is and the distance between the two charged objects
Answer:
2:a-heterogenous
b-homogenous
c-heterogenous
d-heterogenous with water
3:Filtration is used to separate insoluble particles from a solution
Distillation is used to separate liquids with close but different boiling points e.g water and ethanol
Explanation:
2: homogenous mixtures form a uniform layer meaning that a mixture containing more than one layer is heterogenous
Answer:
I think is b
Explanation:
if im wrong, heres some information:
mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.[1] While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia.
A range of values is given for the density of gasoline and corn syrup could be because these substances changes their volumes along with the changes in temperature which will result to a change in density as well. Hope this answers the question.
An everyday item that is made of a metal would be simple utensils like a fork. Forks are made of stainless steel which is made of multiple types of metals. A property of metals is that they are generally solid at room temperature and they are hard. This is a necessary property as if the fork was soft, or not even solid, it would be almost impossible to use.
Nonmetals are species that gain electrons and form ions, and are often electronegative elements. A common nonmetal is oxygen or nitrogen gas that makes up a large percentage of the atmosphere. Nonmetals are generally nonconductors, which means they do not conduct heat or electricity well. This is a necessary property because if the air was a good conductor, all electricity would be unstable and many electronics would simply short circuit or catch on fire.
Metalloids are materials that fall between metals and nonmetals in terms of properties. A common metalloid would be boron which can be found in various types of glass. In this form it has the solid property of a metal and the nonconducting property of a nonmetal. If glass were not solid, it would not be able to hold its form, and if glass were a good conductor of heat or electricity, it would make glass materials more dangerous to work with.
