The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity—it is the magnitude of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, meters per second, etc.).

Answer:
The answer is false. First part correct, second incorrect.
Explanation:
The affirmation “The polarity of an oxygen-hydrogen bond is higher than the polarity of a nitrogen-hydrogen bond” is correct: Oxygen is more electronegative than Nitrogen (3.5 O, and 3 N), then when they form a covalent bond with Hydrogen, OH-bond polarity is higher than NH-bond polarity. Nevertheless, the consequence is that alcohols (that have OH characteristic group) are more soluble in water (polar solvent) than amines (NH group). Then, second part of the affirmation is incorrect.

False
