Measuring human impact and comparing it with the biophysical world's carrying capacity is known as Ecological footprint.

<h3>What is Ecological footprint?</h3>

The Global Footprint Network promotes the ecological footprint as a way to assess how much nature is needed to sustain a certain number of people or an economy. Through an ecological accounting system, it monitors this demand. The accounts compare the biologically productive areas used by people for consumption to the biologically productive areas available in a region or throughout the world (biocapacity, the productive area that can regenerate what people demand from nature). It measures the effects of humans on the environment, to put it briefly.

A ball rolls from x=3.85m to x=22.1m in 5 seconds. What was its average velocity

Vadim26 [7]

Answer:

Average Velocity = 3.65 m/s

Explanation:

Average Velocity $=\frac{Total Displacement}{Total Time}$ $=\frac{22.1-3.85}{5}=\frac{18.25}{5}=3.65$

Step one:

given data

Force applied = 22.4 N

distance = 10 meters

<u>Required:</u>

the work done

Step two:

The expression for the work done is

WD= force*distance

substitute

WD= 22.4*10

The chart below shows the amount of coal mined in four different states of USA in the year 2005.

ozzi

The correct answer is <span>Montana.

In fact, we see from the table that Montana is the state with the largest amount of coal mined in 2005: 120 billion tons, while all the other states have a smaller amount of coal mined (37, 68 and 78, for West Virginia, Wyoming and Illinois, respectively).</span>

2. Two people, one on Earth and the other on the Moon, try and lift 200 kg blocks. Which person

Art [367]

Answer:

The person on Earth will have to exert more force to lift their block

Explanation:

The mass of the blocks to be lifted = 200 kg

The location of the first person = On Earth

The location of the second person = On the Moon

The force a person will have to exert to lift the block = The weight of the block = The gravitational force, F, on the block which is given as follows;

$F = \dfrac{G \times M_1}{R^2} \times m_2$

Where;

$\dfrac{G \times M_1}{R^2}$ = The acceleration due to gravity on the Earth or the Moon, depending on the location of the block

m₂ = The mass of the block

Therefore, given that the acceleration due to gravity on the Earth is larger than the acceleration due to gravity on the Moon, the weight of the block on the Earth is larger than the weight of the block on the Moon, and the person on Earth have to exert more force to lift the heavier weight of the block on Earth than the person on the Moon will have to exert to lift the same block as the block has a lower weight on the Moon due to lower acceleration due to gravity on the Moon.

I need help find how much tension is in the string????

Nikitich [7]

Answer:

When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.

Image result for I need help find how much tension is in the string???? And can you explain how you got it after you get the answer plz????

Hence, in such a case the tension will be equal to the centrifugal force.

Formula for tension = centrifugal force = mv2/r.

So the formula of tension will be = centripetal force – force of gravity = mv2/r – mg = m(v2/r-g)

The formula of tension will be = centripetal force + force of gravity = mv2/r + mg = m(v2/r+g)
