the magnetic field in the core of a solenoid is directly proportional to the product of the current flowing around the solenoid and the number of turns per unit length of the solenoid. This, result is exact in the limit in which the length of the solenoid is very much greater than its diameter.

The drift velocity is the average velocity that a particle, such as an electron, attains in a material due to an electric field. It can also be referred to as axial drift velocity. In general, an electron will propagate randomly in a conductor at the Fermi velocity.

When a conductor is subjected to an electric field E, each electron experiences a force
F = - eE, and free electron acquires an
acceleration, a= F/m = - eE/m ... (i)
where, m = mass of electron, e = electronic charge and E = electric field.
Free electron starts accelerating and gains velocity and collide with atoms and molecules of the conductor. The average time difference between two consecutive collisions is known as relaxation time of electron and
{tex}\overline { \tau } = \frac { \tau _ { 1 } + \tau _ { 2 } + \ldots + \tau _ { n } } { n }{/tex} ...(ii)
where, {tex}\tau_{1}, \; \tau_{2}.... \; \tau_{n}{/tex} are the average time difference between 1st, 2nd, ...nth collisions.
{tex}\therefore{/tex} v1, v2, ... vn, are velocities gained by electron in 1st, 2nd, ..., nth collisions with initial thermal velocities u1, u2, ..., un, respectively.
{tex}\therefore \quad { v } _ { 1 } = { u } _ { 1 } + { a } \tau _ { 1 }{/tex}
Similarly,
{tex}\mathop {{v_2}}\limits_ \vdots = \mathop {{u_2}}\limits_ \vdots + \mathop {a{\tau _2}}\limits_ \vdots {/tex}
{tex}{v_n} = {u_n} + a{\tau _2}{/tex}
The drift speed vd may be defined as
{tex}v _ { d } = \frac { v _ { 1 } + v _ { 2 } + \ldots + v _ { n } } { n }{/tex}
{tex}v _ { d } = \frac { \left( u _ { 1 } + u _ { 2 } + \ldots + u _ { n } \right) + a \left( \tau _ { 1 } + \tau _ { 2 } + \ldots + \tau _ { n } \right) } { n }{/tex}
{tex} { v } _ { d } = \frac { \left( { u } _ { 1 } + { u } _ { 2 } + \ldots + { u } _ { n } \right) } { n } + \frac { { a } \left( \tau _ { 1 } + \tau _ { 2 } + \ldots + \tau _ { n } \right) } { n }{/tex}
{tex}v _ { d } = 0 + { a } \tau{/tex} [{tex}\because{/tex} Average thermal velocity in n collisions = 0]
{tex}{ v } _ { d } = - ( e { E } / m ) \tau{/tex} [from Eq. (i)]
This is the required expression of drift speed of free electrons in a conductor in a presence of voltage source.

P=mv

Ramakant Kushwaha 1 day, 13 hours ago

Mementum is the product of mass and velocity

Nitish Yadav 1 day, 23 hours ago

Momentum = mass • velocity In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as p = m • v where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity. The units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s. While the kg•m/s is the standard metric unit of momentum, there are a variety of other units that are acceptable (though not conventional) units of momentum. Examples include kg•mi/hr, kg•km/hr, and g•cm/s. In each of these examples, a mass unit is multiplied by a velocity unit to provide a momentum unit. This is consistent with the equation for momentum.
