Answer:
Hence wavelength of the photons produced by the laser is
Explanation:
Given
Efficiency of laser - 30%
As we know
h = plank's constant
c = speed of light
eV0 = band gap
Hence wavelength of the photons produced by the laser is
Answer:
first step here is to substitute the 3 of your two equations into the second;
3 Ne^(-Q_v/k(1293)) = Ne^(-Q_v/k(1566))
Since 'N' is a constant, we can remove it from both sides.
We also want to combine our two Q_v values, so we can solve for Q_v, so we should put them both on the same side:
3 = e^(-Q_v/k(1293)) / e^(-Q_v/k(1566))
3 = e^(-Q_v/k(1293) + Q_v/k(1566) ) (index laws)
ln (3) = -Q_v/k(1293) + Q_v/k(1566) (log laws)
ln (3) = -0.13Q_v / k(1566) (addition of fractions)
Q_v = ln (3)* k * 1566 / -0.13 (rearranging the equation)
Now, as long as you know Boltzmann's constant it's just a matter of substituting it for k and plugging everything into a calculator.
Answer:
It adhears well underwater.
Explanation:
Once you cut the tape and place it on the leak, it stops the water almost immediatly. It had a rubber backside so underwater it holds well.
Answer:
(B) dimensions, tolerances, materials, and finishes of a component.
Explanation:
An engineering drawing :
An engineering drawing is a technical drawing which draws the actual component .
An engineering drawing shows
1. Materials
2.Dimensions
3.Tolerance
4.Finishes of a component
Engineering drawing does not shows any information about the cost of component.
So the option B is correct.
