Answer:
Pollution is a really big problem in our planet and it must be stopped immediately. It must be stopped before our planet goes extinct. There are three main reasons, in my opinion, why pollution should be stopped. We can’t keep living in some of the conditions our planet is on because of us and what we do to it.
The first reason why we should stop pollution is that pollution is destroying the environment we live in. Power stations produce nearly 10 billion tons of carbon dioxide per year. Carbon dioxide is a big contribution for pollution. Carbon dioxide affects our climate in many different ways. The way it works is that basically certain 'greenhouse gases' can't escape from our atmosphere because they get trapped. CO2 is what plants need to create oxygen. But when there is too much carbon dioxide being admitted into our environment from burning fossil fuels, cars etc, and we are cutting down trees for paper, it is imbalanced. Pollution is the introduction of harmful contaminants into an environment that causes instability, disorder, harm or discomfort to living organisms and ecosystems.In 1987, the U.S. released 1.2 million tons of toxic chemicals into our atmosphere, 670,000 tons into our soil, and 250,000 tons into our water. 40% of America’s rivers and 46% of America’s lakes are too polluted for fishing, swimming, or aquatic life. This shows that water pollution, air pollution, and ground pollution are common
The second reason why we should stop pollution is that it also affects us humans. Pollution also affects human life and that is a big problem. According to the US-EPA, emissions from power plants contribute to over 2,800 lung cancer deaths and 38,200 heart attacks annually in the US. The risk of cancer from breathing diesel gas is about ten times more than ingesting all other toxic air pollutants combined, with diesel emissions contributing to over 70% of the cancer risk from air pollution in the USA. both developing and developed nations, fossil fuel consumption- mostly by industry, vehicles and power plants, releases air pollutants such as particulate matter, sulfur dioxide, nitrogen dioxide, and ground-level ozone. According to the World Health Organization, indoor air pollution from the burning of coal or biomass fuels like wood jeopardizes perhaps half of humanity. Air pollution causes 2 million deaths per year, mostly from heart disease and respiratory disorders like infections and lung cancer.
The third reason why we should stop pollution is that if we do, we can live longer on this planet. If we dont stop pollution and global warming, something really bad will happen to every. Our existance, humans, won’t be over if we do the right thing if we all help the environment. Modern humans have been on Earth for 200,000 years and in those years, humans have destroyed the planet so quick. We can live longer and extend our existance on this planet so that our children’s children’s can live in a planet without worries.
In conclusion, pollution must be stopped immediately and once in for all. This is our only home and we must protect it and take care of it as much as we can. pollution must be stopped before we ruin our planet. We can live anywhere else, therefore we must try to save it.

The average woodpecker smashes its beak against a hard surface more than 10,000 times a day. Any human who jolted their head like this would likely end up with a concussion. This traumatic brain injury is caused by a blow to the skull. So why doesn’t the constant hammering turn woodpeckers’ brains into mush? For years, it was assumed that woodpeckers had some kind of cushioning in their heads to protect their brains during pecking. Many scientists suggested that spongy bone in the birds’ skulls absorbed and lessened the shock of each impact (see Myth Buster: Hard Headed). This idea was repeated in scientific articles, textbooks, and informative plaques at zoos. Even though the concept “is often presented like a clear-cut fact, there haven’t been any real tests to prove it,” says Sam Van Wassenbergh. He’s a biologist who studies biomechanics, or how living things move, at the University of Antwerp in Belgium.SHOCK ABSORBER: Van Wassenbergh uses a spring-loaded hammer to show why a shock-absorbing skull would make a woodpecker less efficient at pecking. When you think about it, says Van Wassenbergh, the shock-absorbing skull idea doesn’t make much sense. Woodpecker drills into the wood in search of insects to eat. When the bird’s head accelerates forward, the movement generates kinetic energy. This energy of motion is transferred to the tree when the bird slams its beak against the trunk. If a woodpecker’s skull had to cushion, it would absorb some of this energy and decrease the force of the peck. Why would a bird that survives by pecking evolve to do it less effectively? Van Wassenbergh and his team decided to see what was really going on. First, the researchers recorded videos of woodpeckers’ heads in motion. To capture this rapid movement, the scientists needed special high-speed cameras. Each peck lasts only a fraction of a second! Van Wassenbergh’s team recorded videos of six woodpeckers from three species and analyzed the footage. The researchers used a computer to track three points on each bird’s head: one on the skull and two on the beak. The scientists hypothesized that if the birds’ skulls had shock absorbers, the footage would show a “squishing” of the space between the skull and beak—like when a spring compresses. But that didn’t happen. Instead, the birds’ heads moved as one stiff unit, like a hammer. Next, the team wanted to demonstrate why this adaptation would be helpful to the birds. Using computer models, the scientists simulated woodpecker skulls with and without shock absorbers. Then the researchers compared the force of the pecks. “The pecking performance was greatly reduced in the skull with a shock absorber,” says Maja Mielke, a biologist who worked on the study. With shock absorbers, says Mielke, “the poor birds would need to pound even harder to reach the same results.” For a woodpecker, having a shock-absorbing skull would simply be a waste of energy. Science World originally published this diagram in our May 10, 2021, issue. It was based on scientists’ beliefs about woodpecker anatomy at the time. Here it is again—updated based on new research. MYTH: The skull is made of spongy bone that cushions and protects the brain from impactBUSTED! The skull is hard enough to protect the bird from injury, but it doesn’t cushion The eyes have a special membrane that protects them from flying splinters and wood dust.MYTH: Neck muscles are strong and stiff enough to absorb the shock of each peck BUSTED! Stiff neck muscles do not absorb shock—in fact, they help increase the force of each peck.MYTH: The tongue wraps completely around the outside of the skull, providing an additional level of cushioning, and can extend to probe for food inside holes made by the birdBUSTED! The tongue does not provide any observable cushioning. The beak is connected to the skull with thick bone that prevents jolts and vibrations. NEW RESEARCH SHOWS: The woodpecker’s brain is small, which helps prevent concussions that might occur in a larger animal. If woodpeckers’ skulls don’t absorb shock, then why doesn’t constant pecking damage the birds’ brains? To answer this question, the researchers calculated how harmful the blows from pecking actually are. It turns out the hits aren’t that dangerous because the birds’ brains are so small. “Small masses can tolerate stronger impact forces without being damaged,” says Mielke.
Answer:
The topic of the story is about how woodpeckers can peck without causing damage to their brains.
"The average woodpecker smashes its beak against a hard surface more than 10,000 times a day."
"This traumatic brain injury is caused by a blow to the skull."
"So why doesn’t the constant hammering turn woodpeckers’ brains into mush?"
The conclusion of the story is that woodpeckers don't get brain damage from pecking because their brains are small, which allows them to handle the force of the pecks.
"Small masses can tolerate stronger impact forces without being damaged,"
"The hits aren’t that dangerous because the birds’ brains are so small."
"To answer this question, the researchers calculated how harmful the blows from pecking actually are."

With his knowledge, in 1763, he repaired a "Newcomen" engine owned by the university. However, while repairing it, he was impressed by its waste of steam, and came upon a solution, the separate condenser. It was his first invention, and he created it in 1769. In 1765, he produced his first working model of the 'Watt' engine (with separate chambers for piston and steam). (i rly hope this helps no need to mark branliest if it doesnt)

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Answer:
1. plasmas
2. special physical forces.
3. solids.
you are most welcome! :D
Answer:
Refer to the explanation.
Explanation:
1.) Plasma is a lot like gases, but the atoms are different because they are made up of free electrons and ions of the element.
In a gas, the atoms or molecules are mostly neutral and not ionized. However, in plasma, the gas is ionized, meaning some or all of the atoms have gained or lost electrons, resulting in the presence of free electrons and ions. These free electrons and ions make plasma distinct from gases and give it unique properties, such as the ability to conduct electricity and respond to magnetic fields.2.) Elements and compounds can move from one phase to another phase when special conditions or factors (such as temperature, pressure, or the addition/removal of heat energy) are present.
The phase of a substance refers to its physical state, such as solid, liquid, or gas. The transition between these phases can occur under specific conditions. Generally, substances change phase when certain thresholds of temperature and pressure are reached, but other factors can also play a role. For example, when a solid is heated to a certain temperature (its melting point), it can transition to a liquid phase, and further heating can turn it into a gas. Similarly, changing pressure can cause phase transitions, such as when a gas is compressed to a certain pressure, causing it to condense into a liquid.3.) The atoms inside of a solid are not allowed to move around too much.
In a solid, the atoms or molecules are tightly packed and held together by strong intermolecular forces. This close arrangement and strong bonding restrict the movement of atoms or molecules, keeping them relatively fixed in their positions. While atoms in a solid can still vibrate around their equilibrium positions, they generally do not have enough energy to move freely throughout the substance like in liquids or gases. This lack of mobility gives solids their characteristic rigidity and shape.
The rover Spirit is a robotic probe that NASA has placed on Mars. The
gravitational attraction of Mars is approximately 62% less than that of Earth. Compared to its measurements on Earth, on Mars the probe has
-the same weight and the same mass.
-a larger weight, but smaller mass.
-a smaller mass and larger weight.
- a smaller weight and the same mass.
Answer:
D) a smaller weight and the same mass is the answer
Explanation:
The rover Spirit is having a smaller weight and the same mass on Mars because of the Strength of Gravity on Mars
The Strength of Gravity depends on the mass of the object as gravity is directly proportional to mass which means more mass more gravity and vice versa
Another example of an object-to-gravity relation is SUN as Sun is the biggest object in the solar system it has the greatest Gravitational pull which is keeping the planets in the solar system intact and in their paths

Your friend Lisa comes to you saying, “I want to borrow $7,000 for a new car and the auto dealership came back to me with this offer. I don’t understand what this all means. And...why will I end up paying $8,119.78?” How would you respond to Lisa so that she understands the conditions of the loan offer?
The total amount you'll end up paying is $8,119.78, which is more than the amount you're borrowing. This is because the interest on the loan adds up over time.
What are the conditions of the loan provider?They are offering you a loan of $7,000 with an interest rate of 6.5%. The loan term is 48 months, which means you have four years to repay the loan.
Based on these terms, your monthly payments will be $170.41.
However, the total amount you'll end up paying is $8,119.78, which is more than the amount you're borrowing. This is because the interest on the loan adds up over time.
To put it simply, the dealership is lending you $7,000, but they are also charging you 6.5% interest on the amount you borrow. This means that for every month you keep the loan, you'll pay some interest, which adds up over time. By the end of the 48-month loan term, you'll have paid back the $7,000 you borrowed, plus the additional $1,119.78 in interest.
So, before you decide to accept the loan offer, it's important to understand the total cost of the loan and whether the monthly payments fit into your budget. You may also want to shop around and compare loan offers from different lenders to find the best deal for you.
Therefore, you'll have paid back the $7,000 you borrowed, plus the additional $1,119.78 in interest. which is greater than the borrowed.

A ball bounces on the ground. How do the ball and the ground act on each other?(1 point)
A. The ball exerts a stronger force than the ground but in the same direction.
B. The ball and the ground exert forces on each other with equal magnitude and in the same direction.
C. The ball and the ground exert forces on each other with equal magnitude but in opposite directions.
D. The ball exerts a stronger force than the ground and in the opposite direction.
If a ball bounces on the ground, Then the ball and the ground exert forces on each other with an equal magnitude but in opposite directions. The correct option is C.
What is Newton's third law of motion?Newton's third law of motion, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
In other words, forces always occur in pairs. When you push on a wall, for example, the wall pushes back on you with an equal force in the opposite direction. This is why you don't fall through the wall when you push on it.
This law applies to all objects, regardless of their size or speed. It is one of the fundamental principles of physics and is used to explain many everyday phenomena, such as why a balloon moves forward when air is expelled from it or why a boat moves forward when it pushes water backward.
Newton's third law of motion is important in many fields of science and engineering, including mechanics, aerodynamics, and rocket science. It plays a key role in the design and operation of many machines and devices, from cars and airplanes to rockets and satellites.
Here in the Question,
When a ball bounces on the ground, the ball exerts a downward force on the ground due to its weight. This force causes the ball to compress and deform slightly as it collides with the ground. At the same time, the ground exerts an equal and opposite force on the ball, known as the normal force. This force pushes the ball upward and causes it to rebound from the ground.
According to Newton's third law of motion, for every action, there is an equal and opposite reaction.
So, the force exerted by the ball on the ground is equal in magnitude but opposite in direction to the force exerted by the ground on the ball. This is why the ball bounces back up into the air after colliding with the ground.
Therefore, the ball and the ground act on each other with equal and opposite forces.
