While many people might scoff at the very concept, light pollution is fast becoming a serious problem. Light pollution most comm

only occurs when the beam of a high-wattage fixture is aimed toward the sky. When a spotlight is used to illuminate statues or buildings, for example, some of the light falls on its intended target, while the rest of the light beam is left to scatter into thin air. The result is an effect called urban sky glow, which is essentially a giant shroud of misdirected light that hangs over a city in the night sky. While some may find this phenomenon picturesque when seen from an airplane, it is the reason why only the very brightest stars are visible to citizens of urban environments. As light pollution continues to increase, it is entirely possible that future generations of city dwellers will not be able to see any stars at all.
Humans are not the only victims of light pollution; some wildlife species are adversely affected as well. Nocturnal animals such as owls and bats are driven from their own habitats when excessively bright lighting is introduced to these areas. As the growing amount of light pollution causes the habitats of nocturnal creatures to shrink, they will have a more difficult time finding food and breeding successfully. This will inevitably result in a serious population decline unless something is done to keep light pollution in check.

Light pollution is a prime example of how most humans habitually consume energy without any consideration of the consequences. It is time that we stop turning a blind eye to the state of the world around us. Working to reduce light pollution is the perfect place to start. Is it truly necessary to have 50 spotlights illuminating trees on a corporate lawn? Is it essential for a restaurant that closes at midnight to have a flashing neon sign operating around the clock? Was the new outlet mall's grand opening only a success because of the 2-megawatt searchlights that hurtled their beams at the stars? Nothing is gained from such blatant waste of light energy.

What is the purpose of this essay?


A.to make readers aware of the potential harm caused by light pollution and persuade them to take measures to control it

B.to inform readers about nocturnal animals facing extinction and persuade readers to take steps to protect those species

C.to create interest in environmental science and encourage students to take it up as a career or a life concern

D.to convince readers of the need to reduce the consumption of electrical energy and suggest strategies for doing so

While none of the answers is what I consider the main idea of this essay, I believe that C is the best possible answer. Each of the paragraphs discusses how particular groups are impacted by the use of lights in urban areas. 
hope this helped :)

Answer:

A. to make readers aware of the potential harm caused by light pollution and persuade them to take measures to control it

Explanation:

The text above is an informative text that aims to show the damage that light pollution can cause in the urban environment and in the wild environment. The text shows that this type of pollution is caused by a waste of energy, which in addition to preventing us from contemplating a starry sky, has a negative impact on wildlife and nature in general. The text also shows that there is a need for us humans to take steps to remedy this situation and reduce or even end visual pollution.

For this reason, we can say that the purpose of this text is to make readers aware of the possible damage caused by light pollution and to convince them to take steps to control it.

A greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.

<h3>What is kinetic energy?</h3>

It should be noted that kinetic energy simply means a form of energy of an object due to motion.

In this case, a greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.

Lapatulllka [165]

There are different variations in population size.  The best reason why the simulation of the sampling distribution is not approximately normal is that The sample size was not sufficiently large.

<h3>What takes place if a sample size is not big enough? </h3>
  • When a sample size taken by a person or a researcher  is not big or inadequate for the alpha level and also analyses that one have chosen to do,  it will limit the study statistical power.

Due to the above, the ability to know a statistical effect in one's sample if the effect are present in the population is greatly reduces.

See full options below

Which of the following would be the best reason why the simulation of the sampling distribution is not approximately normal?

A The samples were not selected at random.

B The sample size was not sufficiently large.

с The population distribution was approximately normal.

D The samples were selected without replacement.

E The sample means were less than the population mean.
