Example 2: The conductivity of n-side in the Ge PN junction is 10 s/m and for the
p-side is 10's/m. Find the built in potential for the junction at 300°K?
where n; = 2.5 x 1019mm = 0.36 m2/v. s and
0.36 mº/v. s and p = 0.16 mº/v. s. I hope you answer me​

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
