I am not sure what exactly you mean by "reactive power" (I guess you mean electrical reactive power), but power is the ratio of energy for a period of time. So that makes power (and reactive power as well) a scalar, since you can describe it with only one number. The fact that electrical reactive power is drawn on a XY plane, should not confuse you.
What else can I help you with?
What is gyroscopic planes?
The plane in which the reactive gyroscipic couple acts is called the gyroscopic plane
What is meant by the term power overlap?
Like, Power Redundancy?
Are there gears in power drills?
Yes there are. There are sliding gears inside power drills.
What is the unit of power in british engineering system and us system?
horse power
What are the features of capability maturity model?
The capability maturity model focus on process improvement, measured and controlled, characterized for the organization and is proactive, and projects. This project is often reactive, unpredictable, and this also used for appraisal program and administrative services.
Is power a vector or scalar?
vector
Area is scaler or vector quantity?
Well it is technically a vector because it has a magnitude and a direction on zero degrees. Reactive power will have a direction of either + or - 90 degrees and apparent power will be the vector sum of the real and reactive power.
Is power scalar quantity?
Power can be scalar or vector, e.g d/dt torque = vector power; d/dt mcV = mcA a vector power.
What is a scalar times a vector?
A scalar times a vector is a vector.
Is power a vector quantity or a scalar quantity?
vector, power= work/time and work= force * distance, force is vector.
Is inertia is a scalar or vector?
vector
Can you add a scalar to a vector?
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Is power momentum a vector or scalar?
Power momentum is a scalar quantity, as it is a measure of the rate at which work is done or energy is transferred. It does not have a direction associated with it, unlike vector quantities such as velocity or force.
Is power a vector quantity?
No, power is not a vector quantity. It is a scalar quantity that represents the rate at which work is done or energy is transferred.
Is time a scalar or a vector?
Scalar
Multiplying or dividing vectors by scalars results in what?
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the scalar.
Is power vector or scalar?
Power is the time derivative of energy, E. Energy can be scalar or vector. Thus power can be scalar or vector. Energy is a quaternion and consists of a scalar or real part Er and a vector part Ev. Energy E=Er + Ev, for example E= FR = -F.R + FxR = -FRCos(x) + FRsin(x). The real part is a scalar called "Energy" and the vector part is called "Torque" but has the same units Joules. Energy is defined by the units. P=dE/dt = d(Er + Ev)/dt = dEr/dt + dEv/dt = Pr + Pv. Power can be a scalar or a vector or both.
