After the emulsion is made, fuel droplet containing water droplets increase its temperature inside the engine, because of that, water droplets explode causing water rapid evaporation that break down fuel droplet, in consequence, smaller fuel droplets are generated. This makes the temperature of the flame during the combustion decrease, and that is why the reduction of NOx is accomplished by this method
.
In the case above, the sum of forces on node 2 (upper-left) is said to be zero.
<h3>What is net
force?</h3>
If any object is said to be falling at constant speed. The net force is often known to be zero.
in the case above, you see that 2 and 3 node is falling down therefore, node 1 and 4 will be zero.
So, In the case above, the sum of forces on node 2 (upper-left) is said to be zero.

Answer:
Nuclear attack(tornado, tsunami)
Explanation:
Well, at those attacks, when being on surface can be dangerous. So, any kind of disturbed oxygen (eg with some gas attack). Also when there is an air strike for example.
