<span>The density of the energy that is transported under the waves under the ocean surface is about five times higher compared to the wind energy 20 meter (about 65 feet) above. In other words, the amount of energy in a single wave is very high. However it turns out that when they tried to make the high power of the waves to power things in a house it only made it past the first few stages there were very few that made it to some stages. This started taking place in around 2001. hope this helped if not let me know and i could explain more:)

Answer:
a) 
b) 
Explanation:
Given that:
- mass of rod,

- length of the rod,

<u>(a)</u>
<u>Moment of inertia of rod about its center and perpendicular to the rod is given as:</u>



(b)
<u>Moment of inertia on bending the rod to V-shape of 60 degree angle and axis being perpendicular to the plane of V at the vertex.</u>
<em>We treat it as two rod with axis of rotation at the end and perpendicular to the plane of rotation. </em>
<em>So, the mass and the length of the rod will become half of initial value.</em>
