Answer:

A. They are extremely difficult to extinguish because fuel obviously is abundant and oxygen can enter easily, even through joints in surrounding rock.

Coal bed fires refers to spontaneous combustion which are triggered by human activity (mining), lightning, wildfires etc.

This usually happen underground when the coal beds are exposed to oxygen as a result of mining activities or human induced fires or combustion.

For this assignment, you will conduct research and evaluate how various roads that have been built in rainforests impact people
Karo-lina-s [1.5K]

i.

There are many foods and products that we consume that come from rainforests. In terms of food, we can identify items such as banana, citrus, cassava, avocado, cashews, Brazil nuts, vanilla, sugar, coffee, tea and cocoa. In terms of products, many ingredients for medicine come from the plants of the rainforest, as well as materials such as rubber, oils, gums, and resins.

ii.

Transportation within the rainforest can help the people who live there. Roads can allow them to access schools, hospitals, markets and other communities. This can make their lives happier and safer. However, roads might be negative for the animals and indigenous communities that live in the area, as they can disrupt their environment and way of life.

Roads and means of transportation are usually positive for tourism, as these allow tourists to reach more places easily.

ii.

Deforestation on rainforests and other natural environments can have a devastating effect on the whole world. First, it leads to the loss of many animal and plant species, decreasing the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. Deforestation also has a negative effect on climate change, as trees are able to absorbe an enormous amount of greenhouse gas emissions. Without them,  the greenhouse effect is amplified, worsening climate change.

Find the coordinates of the centroid of the triangle with the given vertices (5, 5), T(11,−3), U(−1, 1)
pentagon [3]

Answer:

Centroid = (5, 1)

Explanation:

Given:

S(5, 5), T(11,−3), U(−1, 1)

Required:

Coordinates of the centroid of the triangle

SOLUTION:

Formula for centroid for coordinates to find the centroid of a triangle = (\frac{x_1 + x_2 + x_3}{3}, \frac{y_1 + y_2 + y_3}{3})

Where,

(5, 5) = (x_1, y_1)

(11,−3) = (x_2, y_2)

(-1, 1) = (x_3, y_3)

Plug in the values into the formula:

(\frac{5 + 11 + (-1)}{3}, \frac{5 + (-3) + 1}{3})

(\frac{15}{3}, \frac{3}{3})

Centroid = (5, 1)
