Answer: because the plane of coot is hot
Explanation:
Answer:
P-waves travel through liquids and solid while S-waves only travel through solids.
Explanation:
Scientists are able to use the fact that P-waves travel through both solids and liquids and waves travel through only solids to determine what makes the different layers of the Earth.
Answer:
The final energy of the system is 168 J
Explanation:
Heat energy released to the surroundings,
Work done, W = 222 J
The initial internal energy,
The change in internal energy is given by the formula,
The final energy of the system is 168 J
Answer:
I think That All the atoms of a given element are identical in that they have the same number of protons
Explanation:
Answer:
A. polymerization
Explanation:
Synthetic plastics are made by linking many simple carbon molecules together to form much larger molecules. This process is called polymerization.
Synthetic or artifical giant molecules consists of synthetic polymers such as plastics, elastomers etc. They are made up of simple monomers which links to form the complex and giant structure.
Monomers are the simplest unit of polymers. Polymers have very great sizes. The size mkaes their structure quite complex. This makes the molecules more disposed in a regular pattern with respect to one another.
The complexity of structure and the attendant effects accounts for the properties and uses that makes synthetic molecules very unique. For example, plastics can be extruded as sheets, pipes and or moulded into other objects.
