At what temperature the semiconductor behaves like conductor?​
hammer [34]

Answer:

A semiconductor acts like an ideal insulator at absolute zero temperature that is at zero kelvin. It is because the free electrons in the valence band of semiconductors will not carry enough thermal energy to overcome the forbidden energy gap at absolute zero.

A cardinal (Richmondena cardinalis) of mass 4.00×10−2 kg and a baseball of mass 0.146 kg have the same kinetic energy. What is t
sp2606 [1]

Answer:

0.5232

Explanation:

the cardinal and the baseball has the same kinetic energy

\frac{1}{2} m_{c} v_{c} ^{2}  = \frac{1}{2} m_{b} v_{b} ^{2}

m_{c}v_{c}^{2} = m_{b}v_{b}^{2}

[4.0X 10^{-2} ]v_{c} ^{2} = [0.146]v_{b} ^{2}

\frac{v_{c} }{v_{b} } = \sqrt{\frac{0.146}{4.0 X 10^{-2} } }

\frac{v_{c} }{v_{b} } = 1.910

Ratio of momentum

\frac{p_{c}}{p_{b}}  = \frac{m_{c}v_{c}}{m_{b}v_{b}} = \frac{ (4.0 X 10^{-2} )(1.910v_{b} )}{0.146v_{b} }

\frac{p_{c}}{p_{b}} = \frac{4.0 X  10 ^{-2} X 1.910 }{0.146}  = 0.5232
