In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
If line BE is the bisector of segment AC, it means that BE divides AC into two equal segments. Therefore, if AB is 7, then AC must be twice that length, making AC equal to 14.
There is no special term "ac" in math, as far as I know. However, in physics, "AC" means "alternating current".
The answer will depend on what ac is: it is not an abbreviation of any standard unit of length.The answer will depend on what ac is: it is not an abbreviation of any standard unit of length.The answer will depend on what ac is: it is not an abbreviation of any standard unit of length.The answer will depend on what ac is: it is not an abbreviation of any standard unit of length.
