The alteration of matter refers to the change in the state or form in which a substance exists. Performing different physical processes on a binder paper such as cutting squeezing, folding soaking, drying shredding and so on are different ways of altering the binder paper.
The state or form of a material can be chanhed from one form or state to another. When a binder paper is squeezed or folded, it's initial state has been altered, cutting or shredding the paper also changes alters it's previous state and so on.
Therefore, the change in the physical state or condition of the binder highlights alteration of the paper.

A The action of his foot striking the ball and the reaction of the ball against his foot.
B The mass of the ball being accelerated from rest by the kicker.
C Air friction slowing the ball as it is flying through the goal posts.
D All of these.
Answer:
The moment the ball leaves the foot, it stops accelerating, and from this point forward only two forces are exerted upon it: the friction with the air, which slows the ball's motion, and gravity, which pulls it down. As the ball moves, it slows and falls down.

Which is a dominant trait that Mendel observed in pea plants?
bumpy pods
short height
yellow seeds
white flowers
A dominant trait that Mendel observed in pea plants are yellow seeds. Yellow seed color dominates over green seed color in peas. Green seeded plant crosses with heterozygous yellow seeded plant.
What is yellow seed ?A content strategy and development company called Yellow Seed works with a variety of brands, agencies, platforms, and formats.
Yellow is the dominant trait and green is recessive for seed color, whereas green is the dominant trait and yellow is recessive for fruit (pod) color. Question: A monohybrid cross was made by crossing a pea plant that produces yellow seeds with a pea plant that produces green seeds.
Either the green color seed trait or the yellow color seed trait is present in the parent plants. One of these features is often dominant over the other, meaning that it is always manifested when inherited. As a result of the dominant nature of the yellow seed color trait, all the progeny exhibit it.
Thus, A dominant trait that Mendel observed in pea plants are yellow seeds.

Which statement most likely describes the relationship between ethylene and polyethylene?
Answer:
Ethylene use falls into two main categories: 1) as a monomer, from which longer carbon chains are constructed, and 2) as a starting material for other two-carbon compounds. The first of these is the single largest use of ethylene, consuming about one-half of the annual output. Polymerization (the repetitive joining of many small molecules into larger ones) of ethylene gives polyethylene, a polymer having many uses, particularly in the production of packaging films, wire coatings, and squeeze bottles. When polymerization is carried out at high pressures and temperatures, the product is called low-density polyethylene and has properties different from the high-density polyethylene formed by polymerization under Ziegler-Natta catalytic conditions (see industrial polymers).

Name two elements that have the same properties as potassium (K)
I know one is calcium
Answer:
sodium and rubidium have the same properties with potassium. this is because sodium, potassium, and rubidium are in the same column that is they are all in group one of periodic table. all are alkali metals hence have the same properties.
Explanation:
The two elements that have the same properties as potassium ( K ) are sodium and rubidium.
What is element ?A chemical element is a species of atoms, including the pure material made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.
Fire, Earth, Water, and Air. Earth, water, air, and fire were the four elements that the ancient Greeks thought made up everything.
Potassium ( K ) and lithium ( Li ) are two elements that share qualities with sodium, since they belong to the same chemical family. The fact that potassium and sodium both have one valence electron and can produce +1 ions explains why their chemical characteristics are similar.
Thus, The two elements that have the same properties as potassium ( K ) are sodium and rubidium.

How does solar radiation affect the thermosphere?
God bless all! :)
Answer:
Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation. ... Radiation causes the atmosphere particles in this layer to become electrically charged particles, enabling radio waves to be refracted and thus be received beyond the horizon.
Explanation:
Answer: How does solar radiation affect the thermosphere?
Explanation: During periods of high solar activity, the X-ray and ultraviolet radiation from the Sun increase, and the thermosphere swells as it sops up this increase in energy from the Sun. As the Sun approaches solar minimum, the thermosphere cools and shrinks as the intensity of the X-ray and ultraviolet radiation decreases.
Explain how ocean currents affect climate
Long-distance transportation of warmed or cooled water is possible with horizontal currents traveling northward or southward.
What is climate?Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of weather factors over a period of time that can range from a few months to many millions of years. Temperature, humidity, air pressure, wind, the precipitation are a few of the meteorological factors that are frequently measured.
Long-distance transportation of warmed or cooled water is possible with horizontal currents traveling northward or southward. The evacuated warm water increases the air's temperature, whereas the cold water is cooled the air, as well as the land surface in which the blows.
Therefore, long-distance transportation of warmed or cooled water is possible with horizontal currents traveling northward or southward.

Lab-Motion
Answer:
this is what I put, I should also mention I got 100% so I doubt its wrong
Explanation:
Newton's second law is a quantitative description of the changes that a force can produce in the motion of a body. "It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it". The momentum of a body is equal to the product of its mass and its velocity. I can include this information in the report or a more detailed version that can make up about 60% of Newton's second law explanation.
