Distillation is a process in many laboratories for the purpose of
separating and/or purifying components of a liquid mixture. The distillation apparatus used consists of
three major parts: <span>distillation flask - to heat the mixture and volatilize the components,
a condenser to cool the vapors back to liquid state, and a collection vessel. The apparatus is typically made of glass and
therefore subject to breakage.</span> <span>All components of the distillation apparatus
should be protected to a stable stand or rack to avoid it from falling over.</span>

<h2>Answer: Neptune
</h2>
The dwarf planet Pluton, <u>has the most eccentric orbit</u> (more elliptical and elongated) of all the planets, and as a consequence its orbit is "intersected" by the orbit of Neptune.
However, <u>despite this intersection, there is no collision risk between these two bodies</u>, since the orbit of Pluto is located in an orbital plane different from that of the other planets and therefore different from that of Neptune, its nearest neighbor. In addition, the orbit of Pluton is inclined 
on the the ecliptic plane (plane where the other planets move around the Sun).
Below are the choices that can be found from other source:
a. 0.3 AU
<span>b. 3.8 AU </span>
<span>c. 30 AU </span>
<span>d. 3 million AU
</span>
Answer is c. 30 AU.

<em><u>Newton's First Law ,</u></em>
F = ma
a = m/F
a = 68 / 59
a = 1.15 m/s2
