Answer:
Between the surface water and the bottom of the pool, the transfer of thermal energy is done by conduction.
Explanation:
The waters on the surface of the pool receive thermal energy from the sun, through the irradiation process. However, when we enter the pool, we realize that the waters at the bottom of the pool are colder than the waters on the surface. This is because the hot water is less dense, that is, lighter than cold water, so the water on the surface of the pool that has been heated by the sun, cannot descend to the bottom of the pool and transfer thermal energy through the process. convection.
In this case, the transfer of thermal energy in the waters of the pool is taking place through the conduction process. Although this process is associated with solid materials, it occurs in the pools very slowly. This process occurs when the heat of the sun heats the water atoms on the surface of the pool, causing these atoms to become agitated and start to bump into each other, transferring heat to each other each time they touch each other. This transfer happens from the surface to the bottom of the pool.
Answer:
Cooperative federalism
Explanation:
Cooperative federalism is also called marble-cake federalism.
It is a flexible arrangement where federal and state governments work jointly on various programmes.
An example of cooperative federalism is hen the national government provides tax revenue to state governments to construct interstate highways. The state government is closer to the project and will more effectively monitor progress.
They can be involved in coordination of the construction and maintenance of the roads.
Answer:
Slavery and Many travelers lost their way.
Explanation:
The target of The western Expansion was the ex-Louisiana territory that's previously owned by France before being bought by United States.
Many states fight over whether the new western territory should be considered as slaves states (where slavery is allowed) or free states (where slavery is illegal.
On top of that, the navigation technology among settlers were still somewhat primitive. So, when they embarked on a journey from Eastern States to Western states, many of them actually lost their way and ended up settling in Midwest or Southern part of United States.
