The force of gravity on earth, no matter the object is approximately 9.8 m/ s2 . The reason the crumpled paper hits the ground first is because of air resistance. A crumpled piece of paper has less surface area than an piece of paper that is not crumpled. More surface area means more air resistance.

Find the statement about Fusion that is false.
stiks02 [169]

Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.

Fusion could be the world's answer to clean unlimited amounts of energy.

Fusion is extremely difficult to contain and maintain here on earth.

Explanation:

Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.

The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.

  • As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
  • it is known that nuclear fusion produces far more energy than fission reaction.
  • It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
  • The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.
