The first five attributes of light are as follows. It has both particle and wave characteristics. Light has been proven to be both a particle and a wave according to quantum physics. The speed of light is greatest in a vacuum because there are no physical constraints on its movement.
Light is a kind of electromagnetic radiation that helps the human eye see or makes things visible. The term "radiation that is visible to the human eye" may also be used to describe it. Photons, which are little energy packets, are present in light.
Light is an electromagnetic wave. Light travels in a straight line. Light is a transverse wave, hence it may pass through any substance. Light's velocity changes as it transitions from one medium to another.

Choose 2 reservoirs depicted in the diagram above and describe how phosphorus moves from one to the other
Phosphorus repositories are tracked down fundamentally in soil and sedimentary rocks, in light of the fact that dissimilar to different supplements that cycle through the biosphere, phosphorus can't be tracked down in that frame of mind in the vaporous state.
Phosphorus moves in a cycle through rocks, water, soil and silt, and creatures. Over the long haul, downpours and enduring reason rocks to deliver phosphate particles and different minerals. This inorganic phosphate is then appropriated in soils and water. Phosphorus can be tracked down on earth in water, soil, and dregs. Dissimilar to the mixtures of other matter cycles phosphorus can't be tracked down in the air in the vaporous state. This is on the grounds that phosphorus is typically fluid at ordinary temperatures and tensions. It is basically going through water, soil, and silt.

A geologist is studying three layers of sedimentary rock in an area. The layers have not shifted from their original positions. The geologist records the relative ages of the rocks. The bottom layer is listed as the oldest. The top layer is listed as the youngest. What did the geologist use to determine the relative ages of the rocks?.
To determine the relative ages of the rocks, the geologist use: the law of superposition. The correct answer is option C.
What is the law of superposition?Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
An example would be that the silt back-fill of an underground drain would form sometime after the ground immediately above it. Other examples of non-vertical superposition would be modifications to standing structures such as the creation of new doors and windows in a wall.

Glaciers can carve out large valleys through mountains.
How do glaciers change the earth's surface?Glaciers move slowly over land and, as part of the cryosphere, interacts with the earth's surface through weathering, erosion and deposition.
Although moving and working slowly, glaciers are major forces of erosion. It can take glaciers years to scratch a bedrock but it can also carve out huge valleys hundreds of kilometers long over thousands of years.
Valley glaciers is a type of glacier which forms when snow and ice buildup in a mountain valley and the high mountains keep the glaciers from spreading out in all directions, and gravity pulls this glacier downhill.

The sediment load that travels in solution is dissolved load.
For particles to be a dissolved load in a stream, they must be smaller and less dense. Pebbles are about -6 mm in size and pebbles are 6-256 mm Sand grains are usually 0.125-2 mm in size, but their average density is high
With minerals, this is different because some minerals are larger and some seem. be smaller. Minerals have the property of dissolving during chemical reactions. Unlike dissolved load, the size of the particle transported as suspended load is determined by the velocity of the flow. As the flow moves faster, it can carry larger and larger particles. The larger the particle size the stream can carry, the higher the qualification of the stream.

agglomeration ap human geography
There is a city center and an area that the city borders. The term "agglomeration" refers to the coexistence of suburban and urban areas.
A city region's built-up area is called an agglomeration, and it can be found both inside and beyond the city center. This AP® Human geography review will cover the definition and significance of agglomeration. Agglomeration, as a complex word that denotes a collection of various objects that are only loosely related, can be said to be. Therefore, Human includes both the central city region and the surrounding territories at the same time. Actually, the phrase means "continuous urbanized area" in French (which fits). In essence, we might think about how things truly suits for various towns and nations as well. Agglomeration basically happens when things are close to one another. A territory cannot be widely dispersed and still be an agglomeration. For instance, it may be a Human that supports other firms that are close to one another.

Your cardiovascular system is progressively revved up during a warmup by increasing body temperature and boosting blood flow to your muscles. Warming up may also help to lessen the possibility of injury and muscle pain. After exercising, cooling down enables a gradual return to pre-exercise blood pressure and heart rate.
Your blood vessels will expand during a decent warm-up before an exercise, supplying your muscles with plenty of oxygen. Additionally, it boosts the temperature of your muscles for maximum flexibility and performance.

It restricts freedom.
It may ignore societal needs.
It slows down innovative developments.
It causes black markets to explode.
It offers no competition.
Explanation:
1. It restricts freedom.
Due to the fact that this type of economic system is tied to communist countries, it is no surprise that it also takes the freedom away from the people and puts full control in the hands of the government alone. People can not choose their careers based on their skills and interests; rather, it is based upon what the government forces them to do. All jobs are aligned with needs at a time, and people have little freedom of choice. This major downside to a command economy can lead to discontented citizens.
2. It may ignore societal needs.
Command economy often ignores the needs of the society for its betterment. Workers will not be given the options on where they can work or where they can move.
3. It slows down innovative developments.
Unlike a free market that encourages change and innovation, a command economy does not offer this advantage. Since the government controls the market, it does not make innovation a priority or does not encourage it all in all. This is because it controls all aspects of production and leaves no room for people to make it better, leading to a workforce that is less motivated to create higher-quality products or services.
4. It causes black markets to explode.
Because of restrictions by the government, some products and services are not offered in the command economy, so they would be offered on black markets.
5. It offers no competition.
Competition on the market is one of the main forces of improvement, but in a command economy, there is little competition. The government owns all the industries and does not encourage competition or actually exerts effort to eliminate it. The benefits gained from competition are not seen in this type of market.
