The drift speed of an electron in a metal is in the order of ??

The drift speed of an electron in a metal is of the order of

Assertion: The drift speed of electrons in metals is of the order of few mm / s and charge of an electron is very small (1.6 xx 10^(-19) C) . Yet a large amount of current is obtained. Reason: At room temperature, the thermal speed of electron is very high ( 10^7 times the drift speed). Which one of the following statements is correct?

What is the drift speed of electrons ?

How does the drift speed of electrons in a metallic conductor vary, when applied potential difference is decreased keeping temperature constant?

A wire of length l and area A is connected to an ideal battery . The drift speed of electrons is v. If the wire is twisted to half its length, what will be the new drift speed ?
