The main offenders in terms of greenhouse gas emissions are?
Mandarinka [93]

The main offenders in terms of greenhouse gas emissions are Asia and Oceania.

<h3>Explanation</h3>

Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.

Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. Whereas Oceania is a geographic region that includes Australasia, Melanesia, Micronesia and Polynesia.  

Asia includes: Bangladesh, China, India, Indonesia, Iraq, Mongolia, Philippines, Sri Lanka and Vietnam. Asia has three main financial centers: Hong Kong, Tokyo and Singapore.

Oceania countries are: Australia, Fiji, Kiribati, Marshall Islands, Micronesia, Nauru, New Zealand, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu

Currently, most of factories that exist in the world are established within Asian and Oceanian region because they have good supply of cheap labours. For example, China was initially one of the lowest labour cost countries known.  They produce the largest amount of pollutant which contain CO2 that contributed greatly to the greenhouse effects.

Hope it helps

A 1380 kg car starts from rest at the
Ulleksa [173]

Answer: 72200

Explanation:

First you must find the height for this is on an inclined hill using:

h=Lsin(angle) —> 28.0sin(11.0) = 5.34

Now you would just use the PE equation (mgh) because you are finding ME and when you starting from the top KE=0, showing that what ever answer you get from PE would equal the same for ME.

Using mgh:

m=1380

g=9.80

h=5.34

(1380)(9.8)(5.34)

=72218.16

*Rounding to the 3rd=72200

Hope this helps :)

A railroad car moves under a grain elevator at a constant speed of 3.20 m/s. Grain drops into the car at the rate of 240 kg/min.
dedylja [7]

Answer:

F = 768 N                  

Explanation:

It is given that,

Speed of the elevator, v = 3.2 m/s

Grain drops into the car at the rate of 240 kg/min, \dfrac{dm}{dt}=240\ kg/min = 4\ kg/s

We need to find the magnitude of force needed to keep the car moving constant speed. The relation between the momentum and the force is given by :

F=\dfrac{dp}{dt}

F=m\dfrac{dv}{dt}+v\dfrac{dm}{dt}

Since, the speed is constant,

F=m\dfrac{dv}{dt}

F=v\dfrac{dm}{dt}

F=3.2\times 240

F = 768 N

So, the magnitude of force need to keep the car is 768 N. Hence, this is the required solution.
