Answer:
Chain reaction is possible by neutron
Explanation:
Nuclear reaction is mainly two types,
⇒ Nuclear Fission : heavy atom split into two light atom.
Ex. Uranium, thorium
⇒ Nuclear fusion : lighter atom combine together
Ex. Hydrogen to helium
In fusion reaction the large amount of energy is produced as compare to fission reaction.
Sun gets brighter by fusion reaction.
In case of uranium fission reaction is possible by colliding neutron.
Answer:

Explanation:
One of the first propulsion characteristics given in the example is that all engines are equal.
In this way if we have 4 engines running at the same time, it means that its capacity is 100%.
Under this premise, if 100% is found, the Jet is capable of reaching a speed of 8.7m / s ^ 2.
However, the question is, what would happen if 2.4 "Engines" now work.
To do this then we make a simple equivalence,
If 4 engines is the equivalent of 100%, when would it be 2.4 engines?

In this way it would mean that the body could be driven to 60% of its total.
So

ANSWER i believe it's A. wax, which is made up of atoms that share electrons equally
(And don't forget that an object going around a curve at a constant speed is also accelerating.)
I believe there are two reasons:
1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.
2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".
