Question 

EXPLAIN AIR POLLUTION WITH ITS MEASURES ,EFFECTS etc IN DETAIL.​

Answers

Answer 1

Answer:

Explanation:

Air Pollution is the release of pollutants such as gases, particles, biological molecules, etc. into the air that is harmful to human health and the environment.”

Effects of Air Pollution:

The hazardous effects of air pollution on the environment include:

Diseases

Air pollution has resulted in several respiratory disorders and heart diseases among humans. The cases of lung cancer have increased in the last few decades. Children living near polluted areas are more prone to pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution.

Global Warming

Due to the emission of greenhouse gases, there is an imbalance in the gaseous composition of the air. This has led to an increase in the temperature of the earth. This increase in earth’s temperature is known as global warming. This has resulted in the melting of glaciers and an increase in sea levels. Many areas are submerged underwater.

Acid Rain

The burning of fossil fuels releases harmful gases such as nitrogen oxides and sulphur oxides in the air. The water droplets combine with these pollutants, become acidic and fall as acid rain which damages human, animal and plant life.

Ozone Layer Depletion

The release of chlorofluorocarbons, halons, and hydro chlorofluorocarbons in the atmosphere is the major cause of depletion of the ozone layer. The depleting ozone layer does not prevent the harmful ultraviolet rays coming from the sun and causes skin diseases and eye problems among individuals.

Effect on Animals

The air pollutants suspend on the water bodies and affect the aquatic life. Pollution also compels the animals to leave their habitat and shift to a new place. This renders them stray and has also led to the extinction of a large number of animal species.

Measures:

Following are the measures one should adopt, to control air pollution:

Avoid Using Vehicles

People should avoid using vehicles for shorter distances. Rather, they should prefer public modes of transport to travel from one place to another. This not only prevents pollution, but also conserves energy.

Energy Conservation

A large number of fossil fuels are burnt to generate electricity. Therefore, do not forget to switch off the electrical appliances when not in use. Thus, you can save the environment at the individual level. Use of energy-efficient devices such CFLs also controls pollution to a greater level.

Use of Clean Energy Resources

The use of solar, wind and geothermal energies reduce air pollution at a larger level. Various countries, including India, have implemented the use of these resources as a step towards a cleaner environment

Answer 2

Explanation:

[tex]\huge{\color{black}{\fbox{\color{pink}{\colorbox{pink}{\color{red}{Answer ✨☑️}}}}}}[/tex]

Air pollution refers to any physical, chemical or biological change in the air. It is the contamination of air by harmful gases, dust and smoke which affects plants, animals and humans drastically. There is a certain percentage of gases present in the atmosphere.

effects

Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects.

The question is incomplete and the full version can be found online.

Answer: Ruby’s purpose in life

Explanation:

The idea that sewing is Ruby´s ministry refers to her purpose in life because that word applies to a calling some people feel to follow a certain path to achieve a specific purpose in life, most likely connected to religious beliefs.

It doesn´t mean that Ruby acts this way because it´s what´s expected of her. Furthermore, saying that Ruby chooses to treat her customers fairly would be incorrect, because her not even charging them is beyond fair treatment. And saying that Ruby’s actions are led by a desire to share her profits would be incorrect, because she wants to help others by not charging for her service, not by giving them money.

Assume that your firm wants to choose between two project options:
Project A: Br. 500,000 invested today will yield an expected income stream of Br150, 000 per year for 5 years, starting in Year 1.
Project B: an initial investment of Br 400,000 is expected to produce this revenue stream: Year 1 = 0, Year 2 = Br 50,000, Year 3 = Br 200,000, Year 4 = Br300, 000, and Year 5 = Br200, 000. Assume that a required rate of return for your company is 10% and that inflation is expected to remain steady at 3% for the life of the project. Which is the better investment? Why?

Answers

Answer: Project B should be chosen as it has a higher NPV of $70,314.97

Explanation:

You need to find the Net Present Value of both projects. The better investment is the one with a higher Net Present Value.

As there will be inflation, this needs to be included in the required return:

= 10% + 3%

= 13%

This will be the rate for discounting.

Project A:

Net Present Value = Present value of cash inflows - Cash invested

Present value of cash inflows:

This is a constant inflow so is an annuity. Present value will be:

= Amount * Present value interest factor of annuity, 5 years, 13%

= 150,000 * 3.5172

= $527,580

Net Present value = 527,580 - 500,000

= $27,580

Project B:

Net Present Value = Present value of cash inflows - Cash invested

= 50,000 / (1 + 13%)² + 200,000 / 1.13³ + 300,000 / 1.13⁴ + 200,000 / 1.13⁵ - 400,000

= 470,314.97 - 400,000

= $70,314.97

Project B should be chosen as it has higher NPV.

The following week, the trainer instructs him to walk a mile and then run a mile until he completes 5 miles. Each week, the training regimen gets harder. By the end of the month, Joshua is running 5 miles without stopping. By the end of the second month, Joshua is running the distance of a half-marathon (approx. 13 miles).

A variable-ratio schedule

Explanation:

The case shown in the question above can be considered an example of a variable-ratio schedule, which is a type of reinforcement scheme in operant conditioning, where a response is observed in the elaboration of an unpredictable number of responses stimulated through repetitive training, or that is, this type of reinforcement scheme encourages the performance of a specific and desired behavior, through various "trainings" with variable responses, until the desired behavior is achieved.

In the case above, the desired behavior was Joshua's ability to run the equivalent of a half marathon. This behavior was stimulated with several trainings that allowed Joshua to run different amounts of kilometers, until he could run the desired amount.
