<span>When an atom undergoes decay its nucleus becomes unstable because it does not have a balance of neurons and protons. This means the atoms try to find a confirmation in which it is stable. In doing so, it is possible that the atom changes its element, and it frees a huge amount of energy in order to balance itself. This is the base of radioactivity.</span>

Answer:

Explanation:
Given that:
- mass of 1 skier,

- inclination of hill,

- length of inclined slope,

- time taken to reach the top of hill,

- coefficient of friction,

<em>Now, force normal to the inclined plane:</em>



<em>Frictional force:</em>



<em>The component of weight along the inclined plane:</em>



<em>Now the total force required along the inclination to move at the top of hill:</em>



<em>Hence the work done:</em>



<em>Now power:</em>



<u>So, power required for 30 such bodies:</u>
