A
absorption
В.
reflected
C.
refraction
O D.
scattering
Answer:
B absorption
Explanation:
because absorption is the transfer of energy carried by light waves to particles of matter
the sand, salt, and water from each other?
(1) Evaporate the water, then filter out the salt.
(2) Evaporate the water, then filter out the sand.
(3) Filter out the salt, then evaporate the water.
(4) Filter out the sand, then evaporate the water.
Answer is (4).
Explanation:
The given mixture contains an insoluble solid and an aqueous solution of salt. The insoluble solid is sand.
First we have to separate insoluble solid. Sand can be separated by doing filtration. When we filter the mixture sand can be seen as the residue on the filter paper.
After filtering the mixture, we should collect the filtrate. Filtrate is the salt solution. By doing evaporation we can get the solid salt.
First and second choices are wrong because after evaporating water filtrationcannot be done and salt and sand will be mixed together.
Salt cannot befiltered out because the salt is soluble and it is inaqueous medium. Hence, third choice is wrong
B) divergent
C) thrust
D) transform
The thrust is not the type of plate boundary.
The outer surface of the earth has been said to be composed of tectonic plates. The tectonic plates give rise to the shape of the zigzag puzzle. The puzzled plate boundaries are present in varying forms based on their shape.
The plate boundaries can be convergent. In this type of boundary, the earth's crust has been coming towards each other. They have been found between the Indian Plate and the Eurasian Plate.
The divergent plate boundary arises in the form of the earth crust moving away from each other. This will give rise to the mountain ranges.
The transform type of plate boundary has been formed when the tectonic plates slide over each other. This type of boundary has resulted in the San Andreas Fault.
The thrust is not the type of plate boundary.

The total amount of energy in the cooler remains the same. The warm soda transfers its heat energy to the ice, causing the soda to cool and the ice to melt. The cooler, soda, and water from the melted ice eventually reach a thermal equilibrium where they have the same temperature.
In the scenario where a student puts a warm can of soda in a cooler filled with ice, the amount of thermal energy in the cooler's system changes due to the process of heat transfer. This process follows the second law of thermodynamics which stipulates that heat tends to flow from hotter objects to colder objects until they reach equilibrium.
In this case, the warmer soda will transfer its heat to the colder ice. During this process, the ice will absorb the heat without a rise in temperature until all of it has melted. This is because this absorbed energy is used to break the bonds holding the ice molecules together in a solid state, causing a phase change to liquid water.
Simultaneously, the soda can's temperature drops as it loses heat to the ice. Eventually, everything in the cooler—the soda, the melted ice water, and the air within—will reach the same temperature, marking the achievement of thermal equilibrium. Therefore, the total amount of energy in the cooler remains the same, it's just transferred (not lost or gained). The energy initially within the can of soda is transferred to the ice, and the overall rise in the cooler’s temperature represent this energy transfer.
