Answer:

Bicycle

Explanation:

A compound machine is a machine which is a combination of simple machines.

Simple machines are like the pulley, inclined plane or a screw.

Suppose a bicycle is considered, it has more than one simple machine combined together, for it to work. Wheel and axle is one of them and the beam which is pivoted at a fixed hinge is another simple machine in it.

The pedals of the bicycle function as the lever.

Using the interactive map, available at ejatlas.org, identify two separate environmental justice issues ongoing anywhere in the
NeTakaya

Answer:

Explanation:

1) The specific issue is the emission of the CO2 gases into the atmosphere and conflicts over coal extraction as leaving the oil in the soil.

2)Land acquisition conflicts and the Agro fuels industries and biomass energy plants are causing more environmental problems.

EJOCT project is meant for considering the causes of climate debt and ecological debt and designed many projects under the clean development mechanism allowing rich countries to offset their emissions by reducing emissions.

Large parts of the global justice movement united around a push for the concept of climate debt in copenhagen climate summit.In the people's summit in Bolivia in 2010, climate debt was considered as the over consumption of the Earth's atmosphere and climate system to absorb green house gases by the developed countries. The map shows the spatial mal distribution of climate change sources and its impacts.

Yes the methods the Summits are taking are correct and can reduce the emission of CO2 gases. The methods they were implementing are supportable to the environment.If the people follow those methods the climate debt can be minimised.I have taken this topic as the emission of CO2 gases is the main problem all the world.Due to this the melting of Ice and Global warming are occuring.This was the main problem to solve all over the world as the no. of Industries and vehicles and population is increasing.These movements are an appropriate way to change and improve the environment in which people have to live.

A point charge of 4 µC is located at the center of a sphere with a radius of 25 cm. Find the electric flux through the surface o
givi [52]

Answer:

Ф = 4.5176x10⁵ N . m² / C

Explanation:

In this case, we need to use two expressions in order to calculate the electric flux of the sphere.

First the Electric flux is calculated using this expression:

Ф = E * A  (1)

Where:

E: Electric field

A: Area of the sphere

To get the electric field E, we use this expression:

E = K * q / r²    (2)

If we replace (2) into (1) we have the following:

Ф = K * q * A / r²    (3)

Finally, we need to know the expression to get the area of a sphere which is the following:

A = 4πr²   (4)

Replacing into (3):}

Ф = K * Q * 4πr² / r²       discarting r²:

Ф = K * Q * 4π   (5)

Now, all we need to do is replace the given values and solve for the electric flux of the sphere:

Ф = 8.98755x10⁹ * 4x10⁻⁶ * 4 * π

<h2>Ф = 4.5176x10⁵ N . m² / C</h2>

Hope this helps
