which component of the Star Wars movies is possible according to our current understanding of physics?
Lena [83]

The movie Star Wars<span> is a space opera interstellar epic which uses science and technology in its settings and storylines, although its main focus is not necessarily on science.</span>

Many elements in the films appear to defy simple laws of physics.<span>
One of which is the falling of spaceships when they are hit by a laser beam. Experts said, this is one good example because without gravity in space, ships should travel in the direction of the impact instead of dropping like a stone.</span>

<h3><u>Explanation;</u></h3>
  • <em><u>Nuclear fusion are nuclear reactions in which two or more atomic nuclei fuse or join to generate different atomic nuclei together with subatomic particles, such as protons or neutrons. </u></em>
  • Additionally,<em><u> nuclear fusion reactions yields lots energy.</u></em> The energy produced is usually more than the energy consumed by the reaction.
  • <em><u>Fusion power  is a form of power generation in which energy generated using fusion reactions is used to produce heat that is used in generation of electricity.</u></em> Energy from nuclear fusion reactions is not coupled by production of wastes.

The intensity of most of the cyclonic storm reduces after hitting land. Explain giving suitable reasons.
yulyashka [42]

The intensity of most cyclones reduces after hitting land because land takes away the heat and moisture of tropical ocean water. In order to survive, cyclone storms need evaporation from the warm sea surface. Intensity also decreases because of greater fiction on land, compared to the sea surface.
