The difference between velocity and relative velocity is that velocity is measured with respect to a reference point which is relative to a different point. While relative velocity is measured in a frame where an object is either at rest or moving with respect to the absolute frame.
<h3><u>Answer</u>;</h3>
C. An object can have acceleration with negative velocity.
<h3><u>Explanation</u>;</h3>
- Acceleration is a measure of the change in velocity over time. The change in velocity is measured in meter per second (m/s), and time interval is measured in second (s).
- Therefore, acceleration measures the change in meters per second every second [(m/s)/s], namely meters per second per second or meters per second squared (m/s2).
- If an object has zero acceleration, its velocity doesn’t have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity.

By comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.
<h3>What is melting point?</h3>
The melting point is the point at which the solid would change to liquid. The boiling point is the point at which a liquid would change to gas. Now we know that the melting and the boiling point of a signature of a compound and can be used to identify a pure substance.
Hence, by comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.
