Canadian nuclear reactors use heavy water moderators in which elastic collisions occur between the neutrons and deuterons of mas
ASHA 777 [7]
M*U + 0 = m*v'1 + 2m*v'2 
the zero means deuteron has no velocity
<span>where v'1 and v'2 are the post-collision velocities. 
</span>The equatio becomes
<span>U = v'1 + 2v'2</span>
<span>U = v'2- v'1 </span>
<span>v'2 = U + v'1 </span>

<span>U = v'1 + 2(U + v'1) = 2U + 3v'1 </span>
<span>U = -3V </span>
<span>V = -U / 3 </span>
<span>The speed ratio is 1/3 </span>

<span>B) Since KE is proportional to the square of the speed, if the speed is 1/3, then KE is 1/9 </span>

<span>C) (1/3)ⁿ = 1/729 </span>
<span>3ⁿ = 729 </span>
<span>n = 6 </span>
