Answer:

<h3>When the surface area is less the pressure exerted by the object is more. However, when the surface area is large, the points of contact between the object and the pressure. Thus, less pressure is exerted by the body on the surface.</h3><h3 />

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 1.25 x 10-4 C charge is moving5200 m/s at 37.0° to a magnetic fieldof 8.49 x 10-4 T. What is the magneticforce on the charge?

juin [17]

0.0003321 Newtons

Explanation

We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation to find the force

$\begin{gathered} F=qvBsinθ \\ where\text{ F is the magnetic force} \\ q\text{ is the charge} \\ v\text{ is the velocity of the charge} \\ Bis\text{ the magnetic field} \\ \theta\text{ is the angle} \end{gathered}$

Step 1

Let

$\begin{gathered} q=1.25*10^{-4\text{ }}C \\ v=5200\frac{m}{s} \\ \theta=37\text{ \degree} \\ B=8.49*10^{-4}T \end{gathered}$

now, replace

$\begin{gathered} F=qvBs\imaginaryI n\theta \\ F=1.25*10^{-4}\text{ C*5200 }\frac{m}{s}*8.49*10^{-4}Tsin(37) \\ F=0.0003321\text{ Newtons} \\ \end{gathered}$

so, the answer is

0.0003321 Newtons

In billiards, the 0.165 kg cue ball is hit toward the 0.155 kg eight ball, which is stationary. The cue ball travels at 5.8 m/s

Damm [24]

Answer:

another ball velocity = 3.92 m/s and with 30° clockwise from initial direction

Explanation:

given data

mass m1 = 0.165 kg

mass m2 = 0.155 kg

before collision velocity v1 = 5.8 m/s

before collision velocity v2 = 0

angle = 35.0° from initial direction

after collision 1st ball velocity v3 = 3.2 m/s

to find out

after collision another ball velocity v4

solution

we consider here ball move in x axis and after collision 1st ball move upside of x axis with angle 35 degree and other ball move downside with x axis with angle θ

so from conservation of momentum we say

m1v1 = m1v3cos35 + m2v4cosθ with x axis .............1

m1v3sin35 = m2v4sinθ with y axis .............2

so from 1 equation

0.165 × 5.8 = 0.165(3.2)cos35 + 0.155(v4)cosθ

v4 cosθ = 3.38 .................3

form 2 equation

0.165(3.2)sin35 = 0.155(v4)sinθ

v4 sinθ = 1.95 ......................4

so magnitude of another ball velocity is square and adding equation 3 and 4

another ball velocity = √(3.39²+1.96²)

another ball velocity = 3.92 m/s

and direction is tanθ = 1.96/3.39

θ = 30° clockwise from initial direction

A 2.75 kg block is pulled across a flat, frictionless floor with a 5.11 N force directed 53.8° above horizontal. What is the tot

Softa [21]

Answer:

F = 3.01 N

Explanation:

Given that,

Mass of a block, m = 2.75 kg

Force applied to the block, F = 5.11 N

It is directed 53.8° above horizontal.

We need to find the total force acting on the block. The force acting on it is given by :

$F=F\cos\theta\\\\F=5.11\times \cos53.8\\F=3.01\ N$

So, 3.01 N of force is acting on the block.

A motor exerts a 280 N force and does 1220 J

finlep [7]

We know that:

Work = Force × Distance

Solving for Distance:

Distance = Work / Force
Distance = 1220 J / 280 N

<h3> Distance = 4.36 m </h3>
