Explanation:
A formula that represents how atoms are linked or joined together is known as a structural formula.
For example, the model given in the image (in question) represents arrangement of all the atoms. Therefore, it is a structural formula.
Whereas a chemical formula represents a compound along with ratio of compounds.
A space filling model and a ball-stick model is a three dimensional model. In space filling model atoms are represented by spheres whereas in ball stick model atoms are represented by ball and bonds are represented by stick.

Hope this helps and pls mark as BRAINLIEST :)
Answer:
See below
Explanation:
F = ma
F = 12 * 9 = 108 N
108 N needed <u> add 30 N more east </u>
As momentum / time = force
so; time = 100÷15
so your answer is 6.7 !!
