The band gab of semi conductor?

Physics
1 answer:
Lerok [7]3 years ago
8 0

Answer:

Properties of semiconductors are determined by the energy gap between valence and conduction bands. To understand, what is semiconductor, we have to define these terms. In solid-state physics, the energy gap or the band gap is an energy range between valence band and conduction band where electron states are forbidden.

What is the electric field 3.9 m from the center of the terminal of a Van de Graaff with a 6.60 mC charge, noting that the field
earnstyle [38]

Answer:

the electric field is  3.91 x 10⁶ N/C

Explanation:

Given the data in the question;

Electric field at a point due to point charge is;

E = kq/r²

where k is the constant, r is the distance from centre of terminal to point where electric field is, q is the excess charge placed on the centre of terminal of Van de Graff,a generator

Now, given that r = 3.9 m, k = 9.0 x 10⁹ Nm²/C², q = 6.60 mC = 6.60 x 10⁻³ C

so we substitute into the formula

E = [(9.0 x 10⁹ Nm²/C²)( 6.60 x 10⁻³ C)] / ( 3.9 )²

E = 59400000 / 15.21

E = 3.91 x 10⁶ N/C

Therefore, the electric field is  3.91 x 10⁶ N/C

notsponge [240]

Answer:

18.032m/s, 16.59m

Explanation:

Used to find the distance traveled

y=1/2gt^2, where y= vertical distance, g=acceleration due to gravity, and t=time

y=1/2*9.8*1.84^2

y=16.59m distance

Used to solve the final velocity before hitting the ground

vf=vo+at where vf=final velocity, vo=initial velocity, a=acceleeration, t=time

vf=0+9.8*1.84

vf=18.032m/s
