18.) CCC Energy and Matter Photovoltaic power from solar panels and biomass
gogolik [260]

Answer:

See Explanation

Explanation:

Renewable energy sources refers to those energy sources that can never be depleted. This means that they can be used severally without getting exhausted. Solar, biomass, wind and hydroelectric power are all renewable energy sources.

Hence, from the perspective described above, we can say that wind is a form of solar energy because wind is formed when the air is heated by the sun.

Hydroelectric power is driven by the water cycle. This water cycle somehow depends on the sun to run efficiently. So, hydroelectric power can also be considered to be a form of  solar energy.

Vanyuwa [196]

Explanation:

Given

mass (m) = 44 kg

velocity (v) = 31 m/s

Now

Kinetic energy

= 1/2 mv²

= 1/2 * 44 * 31²

= 0.5 * 44 * 961

= 21142 joule

Hope it will help you :)
