Answer:
a) 6.8 Volt
b) 1.21Цm
Explanation:
We are given from the question that
The zero -bias depletion layer width(
) is 0.4Цm
The built in voltage φj is 0.85V
Now to calculate the reverse voltage(
) that would be required to triple the depletion - layer width.
The depletion - layer width (
) of the diode has the formula

For three times of
we have

=> 
=> 
Substituting value of φj
We have

= 6.8 V
The required bias voltage
is 6.8 V

Answer:
Drag or air resistance
Explanation:
The force of friction caused by a moving fluid is called drag. When that fluid is air, it's also known as air resistance.
