My answer will be that the valence of the Carbon atom is (+4) and that of each Oxygen atom is (-2). The CO2 molecule is formed by covalent bonds, in other words: C (+4) + O2 (-4) = 0.

What is the other name for the planetary accretion model?
Ivanshal [37]

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

Two ice skaters stand facing each other. The first skater has a mass of 100 kg and the second has a mass of 50 kg. They push eac
olga_2 [115]

The second skater accelerates at 6 m/s^2 to the right.

  • Let the first skater be F.
  • Let the second skater be S.

<u>Given the following data:</u>

  • Mass of F = 100 kg
  • Mass of S = 50 kg
  • Acceleration of F = 3 m/s^2

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;

Force = Mass × acceleration

Substituting the given values, we have;

Force = 100 × 3

<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:

Acceleration = \frac{300}{50}

<em>Acceleration of S </em><em>=</em><em> 6 </em>m/s^2<em />

Therefore, the acceleration of the second ice skater is 6 m/s^2 to the right.
