A is the answer! I’m pretty sure hopefully i helped!!
Answer:

Explanation:
Hello,
Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

Nevertheless, since we've got a angled force, it becomes:

In this case,
accounts for the formed angle, so the horizontal acceleration turns out into:

Explanation:
The boiling point of a substance is affected by the nature of bonding in the molecule as well as the nature of intermolecular forces between molecules of the substance.
2-methylpropane has only pure covalent and nonpolar C-C and C-H bonds. As a result of this, the molecule is nonpolar and the only intermolecular forces present are weak dispersion forces. Therefore, 2-methylpropane has a very low boiling point.
As for 2-iodo-2-methylpropane, there is a polar C-I bond. This now implies that the intermolecular forces present are both dispersion forces and dipole interaction. As a result of the presence of stronger dipole interaction between 2-iodo-2-methylpropane molecules, the compound has a higher boiling point than 2-methylpropane.
