Answer:
The oxidation state of the carbon is +4.
Explanation:
Calcium is in group 2 of the periodic table, therefore, its oxidation state is +2.
The oxidation state of the oxygen is -2.
As the compound is neutral, the sum of the oxidation states of all atoms must be 0.
Oxidation State Ca + Oxidation State C + (Oxidation State O)×3 = 0
+2 + x + (-2)×3 = 0
2 + x - 6 = 0
x = 6 -2
x = 4
Hence, the oxidation state of the carbon is +4.

Answer:
Velocity
Explanation:
The change of velocity rate it's the definition of acceleration.
While increasing or decreasing velocity, it means that an acceleration it's happening.
Using some math:

This can be read as "the acceleration it's equal to te variation of velocity with respect to time"
