some massive black dwarfs may eventually produce <u>supernova explosions. </u>These will occur if pycnonuclear (density-based) fusion processes much of the star to iron, which would lower the Chandrasekhar limit for some black dwarfs below their actual mass.
I barely do my own homework lol
Answer:
Its probably D (the sound energy)
Answer:

Explanation:
Given:
- mass of nerf projectile,

- velocity of nerf projectile,

- mass of the gun,

Now in this case the collision can be assumed to be perfectly elastic.
<u>For an elastic collision:</u>

where:
recoil velocity of the gun
