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:
Sugar can’t enter cells directly
Explanation:
So when blood sugar level rises, cells in the pancreas signal for the release of insulin into the bloodstream. The insulin attaches to the sugars and signals cells to let it enter with the attached sugar. Insulin is known as the key that unlocks cells.

Answer:
632.8 nm is the wavelength (in air) of red light from a helium neon laser.
Old temperature = 283 K.
New temp = 323 K.
(323/283) x (325 kPa) = 371 kPa.
Answer:
Explanation:
From the question, using the expression:
where;
This is a combined intensity of 4 speakers.
Thus, the intensity of 3 speakers = 
= 2.372 W/m²
Thus;
