The ultimate fate of a star depends on its mass.
A massive star ends with a violent explosion called a supernova.
The matter ejected in a supernova explosion becomes a glowing supernova remnant.
Toward the end of its life, a massive supergiant star
has a central iron core, surrounded by a shell where
silicon is being fused to iron, surrounded by a shell
where oxygen is being fused, surrounded by a shell where
carbon is being fused, surrounded by a shell where helium is
being fused, surrounded by a shell where hydrogen is
being fused.
Newton’s first law, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Or in our case an object at rest will stay at rest until an outside force interferes.
Answer:
V = -0.3 m/sec.
Explanation:
5.0 x 0.12 + 2.0 x v = 0. Which means that V = -0.3 m/sec.
The -ve sign shows it moves in the opposite direction.
