The correct answer is option C, Planetesimal assembly
Accretion is the assembling of particle to form a massive object by virtue of gravitational attraction. Most of the celestial objects are formed by the accretion process. Planetesimals is an important step in the formation process of planet which involves the accumulation of dust and ice particles. Thus Planetary assembly work on the same principal of planetary accretion model and hence it can be stated as another name of planetary accretion model
The ocean surface currents circulate counter clockwise direction in the southern hermisphere duebto the coroilis effect.
The second skater accelerates at 6
to the right.
- Let the first skater be F.
- Let the second skater be S.
<u>Given the following data:</u>
- Acceleration of F = 3

To find the acceleration of the second ice skater, we would apply Newton's Second Law of Motion:
Mathematically, Newton's Second Law of Motion is given by this formula;
× 
Substituting the given values, we have;
× 
<em>Force </em><em>= </em><em>300 Newton</em>
<u>Note:</u> The same force is acting on the two ice skaters and the second ice skater would be pushed in the opposite direction (right).
Now, we would find the acceleration of the second ice skater:

<em>Acceleration of S </em><em>=</em><em> 6 </em>
<em />
Therefore, the acceleration of the second ice skater is 6
to the right.
