Kinetic energy is equal to half of an objects mass multiplied by the velocity squared.
B the metals in the core are very heavy
Answer:
Pressure
Surface
Flow
Fluency
Explanation:
*Surface
The surface tension is the force with which the surface molecules of a liquid are attracted to bring them inside and thus decrease the surface area.
*Flow
It is defined as resistance to flow. The viscosity of a liquid depends on the intermolecular forces:
-The higher the intermolecular forces of a liquid, its molecules have a greater difficulty moving between them, therefore the substance is more viscous.
-Liquids that are made up of long, flexible molecules that can bend and tangle with each other are more viscous.
* Pressure
if the molecules of the liquid have a greater intensity of intermolecular force, then they will be trapped in the liquid and will have less facility to pass into the gas phase.
on the contrary to lower intensity of intermolecular force, then the molecules can escape more easily to the gaseous state.
*Fluency
This property allows liquids to easily pass through a hole regardless of size, as long as this hole is at a lower or the same level of the container where the liquid is stored.
This property indicates the deformability of a liquid which is very wide without requiring mechanical stress.
c) migration
Push factors are the reasons why people leave an area. Pull factors are the reasons why people move to a particular area.
