I WANT TO KNOW SOLVING PROCESS

Answer #1

The mean time between collisions in iron is 5.0×10?15 s .
What electron current is driven through a 1.9-mm-diameter iron
wire by a 0.070 V/m electric field?
Express your answer using two significant figures.

1. The electron drift speed in a 3.00-mm-diameter gold wire is
6.00 × 10−5 m/s. How long does it take 1 mole of electrons to flow
through a cross-section of the wire?

2 Drift Velocity The average velocity of electrons in a material
with a scattering time τ is vd = eE me τ. The scattering time also
determines the resistivity of the material: ρ = me ne2τ . Here, n
is the free electron density of the material — the number of free
electrons per cubic meter. (a) Estimate the free electron density
in copper. There is one free electron per copper atom. The mass
density of copper is 8.92 g/cm3...

A 10.0 cm long wire has a 1.50mm diameter and is made of a newly
discovered metal called Oaktonium. This metal has 9.3x10^29 free
electrons per cubie meter and these electrons have a mean time
between collisions of 3.2 x 10^-14 s. The wire is connected to a
1.0 V battery.
Calculate the current through the wire.
I know the answer is 1.481465 x 10^4. I just don't know
how to get that. Need the steps

An electron moving parallel to a uniform electric field
increases its speed from 2.5×107 m/s to
4.5×107 m/s over a distance of 1.4 cm. What is the
electric field strength?

An electron with an initial velocity magnitude of 4 x 10^6 m/s
is at the origin and comes to rest over a distance of 2 centimeters
by a parallel plate capacitor electric field. Find the potential
difference between the origin and the location at which the
electron is at rest.

An electron has an initial speed of 6.64 106 m/s in a uniform

(c) How long does it take the electron...

An electron has an initial velocity of 2×106 m/s in the +x
direction. It enters a uniform electric field E = 410 N/C which is
in the +y direction. By how much, and in what direction, is the
electron deflected after traveling 9 cm in the +x direction in the
field ?

An electron moves at a speed of 19000 m/s in a circular path of
radius 2.2 cm in a solenoid. The magnetic field of the solenoid is
perpendicular to the plane of the electron’s path. The permeability
