It is pretty close to 0. I am sitting at a desk. However, I am also sitting on the planet earth which is revolving on its axis as well as rotating around the sun (approximately); the sun is rotating along with our arm of the Milky Way Galaxy, the Milky Way Galaxy is moving through space towards the Andromeda Galaxy and our local cluster is headed towards ... . My head starts spinning when I think of all the calculations required. Besides, what fixed frame of reference can I use to measure all these movements?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
In direct current the charge carries always flow in the same direction, while in alternating current they change direction repeatedly, meaning overall there is no net direction.
The induced current is maximum when the axis of the conductor, its velocity, and the magnetic field lines are all mutually perpendicular.
the flowing in the conductor is related as given by the relation... I=Vena v=drift velocity of electron e=charge on electron n=concentration of electron in the current carrying conductor . a=area
The individual electrons will move back and forth, as they do when there is no current. You would have to do very careful statistics to notice that there are slightly more electrons moving in one direction than in the other: the drift velocity (average velocity due to current) of the electrons is typically a fraction of a millimeter per second.

mass multiplied by velocity gives momentum.

A current of air with its velocity directed downwards or in a direction below the horizontal. Mathematically v.n < 0 where v is the velocity vector and n is the upward normal at the surface.
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
Acceleration increases the velocity. There are two physics formulas that you can use to see more how they interact. The first is a formula for determining your current velocity at a given moment t, knowing your initial velocity and your current acceleration. v = v0 + at (v0 is v-naught. The zero is usually written as a subscript.) You can solve this equation for a to get a formula for acceleration as well. a = (v-v0)/t So, basically, at any given interval t, the acceleration has been added onto the current velocity that many times.
The relation between electric current and drift velocity is that they both happen to involve electrons moving opposite of the electric field. The electric field must also have a conductor.
If the current is alternating, then it has the properties of a wave in the conductor, such as frequency, wavelength, amplitude, phase, group velocity etc.
it is an instrument to determine the velocity of flow at required point in a flowing stream.
velocity
An object's nature is to adhere to it's current state (by state I mean velocity). With no force applied, nothing will cause it to change its velocity.
