Answer:

$\Delta v = 0.123 m/s$

Explanation:

As per the law of uncertainty we know that

$\Delta p \times \Delta x = \frac{h}{4\pi}$

now we know that

$\Delta x = 0.70 nm$

$m = 6.10 \times 10^{-25}$

also we have

$h = 6.626 \times 10^{-34} J.s$

now we will have

$m\Delta v \times \Delta x = \frac{h}{4\pi}$

$(6.10 \times 10^{-25})\Delta v \times (0.70 \times 10^{-9}) = \frac{6.626 \times 10^{-34}}{4\pi}$

$\Delta v= 0.123 m/s$

DochEvi [55]

Answer:

$Resistivity (rho) = Resistance (G) * Area (\pi r^2) / Length (nm)$

Explanation:

if rho is the resistivity, then according to the proper equation re-arrangement the resistance is G. Then, Area can be calculated by radius and dividing their product by the length of channel.

Answer:

the fractional loss per pass =0.053

the decay time of the cavity =11 ns

Explanation:

laser is an acronym for Light Amplification by Stimulated Emission of Radiation and it has lot of military applications : basically ranging from target acquisition, fire control, and training. It is also being used in LIDAR communications, radar systems , laser guided landing systems, laser pointers, holography, photography, guidance systems, scanning machines, metal working, and medicine.

the fractional loss per pass= $\alpha l - ln(R_1R_2)^ \frac {1}{2}$
