D because it includes both acceleration and direction.

The relationship between the pressure applied to a gas and the volume of the gas is inverse. An increase in pressure reduces the volume of the gas. <span />
Answer:
True
Explanation:
An atom's valance electrons are those electrons that have the highest energy. Atoms tend to be stable and nonreactive if they have the highestvalence electrons. In the periodic table, the number of valence electrons in each element decreases from left to right across each period.
Answer: The incident ray and the reflected ray and the normal will be parallel to each other.
Explanation:
The normal is perpendicular to the surface of the mirror or the reflective surface.
According to the law of reflection which state that:
The angle of incidence is always equal to the angle of reflection on a smooth surface.
If a light ray is incident on a reflective surface along the normal. The angle of incidence will be at 90 degrees which will be perpendicular to the surface of the mirror, the reflected ray will bounce back likewise at the same angle which will be perpendicular to the reflective surface.
Both the incident ray and the reflected ray and the normal will be parallel to each other.
