Sulfur trioxide

Carbon monoxide

Explanation:

  Molecule A is SO₃

  Molecule B is CO

SO₃ is sulfur trioxide formed usually by the reaction of SO₂ with oxygen. The bond type between the molecule is a covalent bond because two non-metals with low electronegativity differences are involved.

Here three oxygen atoms are attached to one sulfur atom.

CO is carbon monoxide. A poisonous gas with a wide range of industrial use. A covalent bond exists between the two atoms.

What is the impulse that a car with a mass of 6kg experiences when its velocity changes from 23m/s to 6m/s?
Elena L [17]
A. 
Impulse is calculated through the equation,

             I = mΔv

where I is impulse, m is mass and Δv is change is velocity. Substituting the known values,

            I = (6 kg)(23 m/s - 6 m/s) 
            I = 102 kg m/s

<em>Answer: 102 kg m/s</em>

B. 
Impulse in this item is calculated by multiplying the force by the time.
    

    I = Force / time = (29 kg m/s²)(7 s) = 203 kg m/s

<em>Answer: 203 kg m/s</em>

C. 
To answer this item, we have to multiply the mass and the velocity to get the impulse and divide the answer by the time to get the force.

        F = m(v)/t

Substituting,
  
        F = (0.1 kg)(-5.69 m/s)/0.64 s 
         F = -0.89 N

<em>Answer: -0.89 N</em>

If the masses of objects increase and their distance from each other remains the same, then the force of gravity between the two
skelet666 [1.2K]

Answer:

the formula for the force of gravity depends  inversely of the distance and directly of the masses.

F_{G} =G\frac{M_{1} M_{2}}{R^{2}}

This means that if the masses increase and their distance remains the same the force will increase proportionally.
