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.

When waves traveling in the same medium meet, a new
wave may be produced. Use the slider to create the resulting
wave with the largest amplitude.
Answer:
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅
Explanation:
When several waves travel in the same direction, the process of adding them can take place.
y_total = ∑ [tex]y_{i}[/tex]
where
y_{i} = A_{i} sin (k x - w t + Ф)
with fi the phase of each wave
To produce the largest possible result, all waves must come with the same phase
y_total = (A₁ + A₂ + A₃ + A₄ + A₅) sin (k x - wt)
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅

6. To which of these abrasive disks can you
apply a water-coolant?
(A) Concrete
(B) Metal
Answer: its B
Explanation:
Metal abrasive disks are used as a water coolant. These are used mostly to slice stones and metals. Grit discs have several advantages over various kinds of discs. They have such a relatively fast cutting speed. The grit disc sander is not a hefty instrument that can be easily held when operating on a scaffold.
Steel cutting fluids are abrasive or peening mediums composed of iron particles. They are typically offered in two sizes (shot and grit) that suit various industrial applications. Since these grains are made from smashed steel shot, they have sharp edges and broken parts.Therefore, the answer is "Option B".

does a atom power a star
Answer: yes
Explanation: All atoms larger than hydrogen and helium have been made within the thermonuclear furnace of a star, powered by nuclear fusion. This is the process in which smaller atoms, i.e., hydrogen and helium, are smashed together to form larger elements, such as carbon.
A bird sitting on a hinged perch takes off from the perch, pushing the perch
in the opposite direction. The momentum of the perch
Answer:
The momentum of the perch is equal to it's own momentum gather to take off
Explanation:
According to the Newton third law of motion which state that: in every action, there will be an equal and opposite reaction.
This is the law that helps us to walk, paddle boats e.t.c.
And momentum is always conserved. Therefore, the momentum of the perch is equal to it's own momentum gather to take off

Answer:
The correct answer is A!
Explanation:
Plz answer both thanks:)
Answer:
Acceleration.
Explanation:
F = m x a
The 'a' in formula above is acceleration.
Force is simply defined as the product of mass and acceleration. Mathematically, it is expressed as
Force(F) = Mass(m) x acceleration (a)
F = m x a

The diagram shows the schematic symbol of a transistor.
Which is the correct label for the part of the transistor
marked with an X?
Х
base
outlet
gate controller
electrical supply
Answer:
base
Explanation:
In the schematic symbol of a transistor, the arrow in the symbol indicates the direction of flow. There are three terminals namely, emitter, collector and base.
When you apply 0.7V from base to emitter you will turn the transistor ON and allow a current to flow from collector to emitter.
With the x in the picture the base must be indicated because all other answers do not make sense.
The correct label for the part of the transistor marked with an X is base.
What is transistor?A transistor is a semiconductor device used to amplify the electrical signals and power. The transistor is one of the important part of modern electronics. It is consist of semiconductor material, have three terminals for connection.

a baseball player throws 4 balls every 20 seconds. what is his throw frequency
Answer:
Frequency, f = 0.2 Hz
Explanation:
We have,
A baseball player throws 4 balls every 20 seconds.
It is required to find the frequency of the baseball.
Frequency of an object is defined as the number of times an event occurs. It is given by number of throws per unit time. It can be given by :
[tex]f=\dfrac{4}{20}\\\\f=0.2\ Hz[/tex]
So, the frequency of his throw is 0.2 Hz.
How far would a baseball travel in 0.5 s if it is thrown at a speed of 20 m/s?

Explanation:
20 ÷ 2 = 10
This is because since it is only half a second, it will only travel half of the distance that is shown in meters per second.

Two speakers create identical 240 Hz sound waves. A person is 1.47 m from Speaker 1. What is the MINIMUM distance to Speaker 2 for there to be destructive interference at that spot? (Hint: v= lambda f=343 m/s) (Unit = m)
Answer: 2.90 metres
Explanation:
Distance of speaker 2 =?
Distance of speaker 1 = 1.47m
Velocity = 343
f = 240Hz
For constructive interference to occur:
Difference in distance or path = wavelength
For minimum distance, n = 1
Distance 2 - distance 1 = nλ
Recall λ = v/f
V = Velocity ; f = frequency
Distance 2 - distance 1 = v/f
Distance 2 - 1.47 = (343/240)
Distance 2 = 1.429 + 1.47
Distance 2 = 2.899 meters
Minimum Distance of speaker 2 for their to be constructive interference = 2.90meters
Answer:
The answer would be 0.755415
