The answer is; The sun will turn into a red giant
This occurs as the hydrogen fuel in the fusion core of the sun begins to deplete. When the hydrogen fuel is depleted, the star begins to collapse on itself due to gravity. This pressure causes the heavier helium to begin fusing in the area around the core. The stars begin to heat up again producing enough energy to push out the outer shells of the star. This causes the star to expand. The outer shells become less hot hence the decrease in luminosity of red giants.
I would say B. A stable home and varied activities
A simple machine can make work easier by reduce the amount of energy needed to perform a task, therefore, B. <span>it magnifies the potential energy so that the kinetic energy is greater</span> is the correct answer.
Explanation:
4 Fe + 3 O₂ → 2 Fe₂O₃
On the left side, there are 4 Fe atoms and 6 O atoms.
On the right side, there are 4 Fe atoms and 6 O atoms.
The reaction is balanced.
Kinetic Energy = (1/2)mv² = 0.5×1627×16² = 208256J
