Answer:
6 atm.
Explanation:
Let the mass of both be m
Then moles of He = m/ 4
Moles of Ne = m/ 20
mole fraction of He = Moles of He/ Total moles = m/4/ (m/4 + m/20) = 0.25 m/0.3m = 0.83
Pressure of He = Mole fraction×total pressure = 0.83 × 6 atm = 5 atm

Explanation:
X-ray emission from the central degrees of the Milky Way Bright X-ray emission traces the coherent edge brightened shell-like feature, dubbed the northern chimney, located north of Sgr A* and characterized by a diameter of about 160 pc. On the opposite side, the southern chimney appears as a bright linear feature. Bright X-ray emission is observed at high latitude

Explanation:
The motion of ballistic pendulum is modelled by the appropriate use of the Principle of Energy Conservation:
The final velocity of the system formed by the ballistic pendulum and the bullet is:
Initial velocity of the bullet can be calculated from the expression derived of the Principle of Momentum:
We don't know the change in velocity, so can't answer.
