Answer:
|F| = 393750 N
Explanation:
Given that,
Total mass of the train, m = 750000 kg
Initial speed, u = 84 m/s
Final speed, v = 42 m/s
Time, t = 80 s
We need to find the net force acting on the train. The formula for force is given by :
F = ma
So, the magnitude of net force is 393750 N.
The attractive force that keeps the nucleus together is called nucleus force.
<span>The nucleus becomes increasingly more stable upon the addition of nucleons up to iron-56.
</span>So, as the size of the nucleus increase more iron 56 are needed.
Iron-56<span> (</span><span>56Fe</span><span>) is the most common isotope of </span><span>iron.</span>
