Germanium to which 1024 m-3 Ga atoms have been added is an extrinsic semiconductor at room temperature, and virtually all the Ga

Svetlanka [38]

Answer:

Electrical Conductivity is 3200 $(\Omega m)^{-1}$

Solution:

As per the question:

$N_{A} = 10^{24}\ m^{- 3}\ Ga\ atoms$

Mobility of electrons, $\mu_{e} = 0.26\ m^{2}/ Vs$

Mobility of holes, $\mu_{h} = 0.020\ m^{2}/ Vs$

Charge, Q = $1.6\times 10^{- 19}\ C$

Now,

The formula for the conductivity is given by:

$\sigma = N_{A}Q\mu_{h}$

$\sigma = 10^{24}\times 1.6\times 10^{- 19}\times 0.020} = 3200(\Omega m)^{-1}$

What three things might influence a slide when conditions are right? What types of material can make up a flow?

Diano4ka-milaya [45]

The three things that can affect a condition to enforce a slide is friction, weight, and slope of an area. Solutions that can make flow easily are those that can create less friction depending on the condition of an environment where it is present. Some of these materials are water, oil, and dense liquids.
