Spring constant is a scalar quantity because it only has magnitude and no direction. It is represented by a single positive value that determines the stiffness of the spring and is measured in units of force per length (N/m).
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
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.
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.
Yes, you can multiply a vector by a scalar. The scalar will multiply each component of the vector by the same value, resulting in a new vector with each component scaled by that value.
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
A scalar times a vector is a vector.

Constant, perhaps scalar constant. Since you could have a constant vector or other object, as well.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.

An earthquake is neither a scalar nor a vector. It is an event.
