Essay on our village our trees wikipedia

Answer. all this r the answer of that question

Step-by-step explanation:

height of the tree is 15√3 m.

width of the river is 15m.

Answer:

Height of tree=15[tex]\sqrt{3}[/tex]m     Distance of Bank from Tree=15m

Step-by-step explanation:

A.T.Q

tan 60°=h/x

h=[tex]\sqrt{3} x[/tex]

Now when Akshat shifts from initial point to the point from where angle seen was 30°

tan 30°=h/x+30

1/[tex]\sqrt{3}[/tex]= [tex]\sqrt{3}[/tex]x/x+30

which gives x= Distance of bank from tree=15m

Height of tree= [tex]\sqrt{3} x[/tex] = 15[tex]\sqrt{3}[/tex]m

Answer:

Explanation:

First of all, planting trees should be given massive attention. Above all, a tree is the source of oxygen. Unfortunately, due to construction, many trees have been cut down. This certainly reduces the amount of oxygen in the environment. Growing more trees means more oxygen. Hence, growing more trees would mean better life quality.

Similarly, people must give attention to forest conservation. Forests are vital for the Environment. However, deforestation certainly reduces the area of forests around the World. The government must launch programs to conserve the forests. The government must make harming forests a criminal offense.

Soil conservation is yet another important way to save the Environment. For this, there must be control of landslides, floods, and soil erosion. Furthermore, there should also be afforestation and tree plantation to conserve the soil. Also, terrace farming and using natural fertilizers are some more ways.

Subject – To give Topmost priority to Soil conservation

Respected Sir,

I am so glad that today I got the opportunity to write a letter to you. I want to convey my message to you that we are facing many challenges regarding our soil and environment because of soil erosion, deforestation, an increase in pollution, etc.

These challenges cause many problems like desertification, loss of infertility of soil, land sliding, loss in the water holding capacity of the soil, less production of crops, vegetables and fruits and also people become homeless, etc.

It is our responsibility to stop all these activities regarding our soil. As you are head of the country and your party has the majority in parliament, so you can make act against it. And ask people to follow that act and get a good result. Also, you have many followers so you can challenge people and aware them of the same.

I humbly request you to Do something to protect the mother of all mothers “the Soil”. If the soil is healthy we will be healthy too.

Hope you look into the matter and try to keep our environment in a good state. I am waiting for your support.

Yours sincerely

The chemical compound sulphur dioxide has the formula

S

O

2

SO2

. It's a poisonous gas that gives out the odour of burned matches. It is generated as a by-product of copper extraction and the combustion of sulphur-contaminated fossil fuels, and it is released naturally by volcanic activity. The odour of sulphur dioxide is similar to that of nitric acid.

Answer:

i) The products obtained are- Carbon and Magnesium Oxide.

ii) The products obtained are- Sulfur and Magnesium Oxide.

Explanation:

(i) The reaction of magnesium with carbon dioxide is redox. Magnesium is oxidized and carbon is reduced. It is highly exothermic. After the reaction is over, we obtain carbon in granules and white magnesium oxide.

[tex]2Mg + CO_{2}[/tex] → [tex]2MgO + C+[/tex]Δ

(ii) The reaction of magnesium with sulfur dioxide is redox. Magnesium gets oxidized and sulfur gets reduced. It is also very exothermic. After the reaction is over, magnesium oxide and sulfur are obtained.

[tex]2Mg + SO_{2}[/tex] → [tex]2MgO+S+[/tex]Δ
