<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:
0.89534 kgm²
Explanation:
= Final angular velocity = 12.9 rad/s
= Initial angular velocity = 5.5 rad/s
= Initial moment of inertia = 2.1 kgm²
= Final moment of inertia
As there is no external torque the angular momentum is conserved
The final moment of inertia is 0.89534 kgm²
Rubbing the balloon on you hair, the hair causes electrons to be added to the balloon. Hence, the balloon would have excesses electrons.
Hence charge on the balloon is negative.
The effect of the silk is to remove electrons, so when the glass rod is rubbed with silk, the silk remove electrons from the glass rod. Hence, since the rod has lossed electrons, it would then be positively charged.
Hence charge on the glass is positive.
Answer:
If the distance between two charged particles is doubled, the force between them changes by a factor of
